- A water-movement model includes these reservoirs: ocean, clouds, land surface, rivers, and groundwater. Arrows show: ocean → clouds (evaporation), clouds → land surface (precipitation), land surface → rivers (runoff), and land surface → groundwater (infiltration). The model links evaporation to Sun's energy and links precipitation/runoff/infiltration to gravity. It also states: "Energy enables movement but does not create water."
Which statement is not supported by the model?
Answer: Because energy is present, the total amount of water on Earth increases as it moves between reservoirs
This question tests understanding of using models to explain how energy moves water through Earth's systems. The Sun provides energy for evaporation, moving water from ocean to atmosphere, while gravity pulls water downward as precipitation and infiltration. Gravity pulls water downward through soil and rock layers during infiltration, moving it from the land surface into groundwater storage. To check which statement contradicts the model, identify what the model explicitly states: "Energy enables movement but does not create water." A common misconception is thinking energy can create new matter, but energy only moves existing water between locations. Water movement in Earth's systems depends on both energy sources working together in the cycle. The total amount of water on Earth remains constant as it moves between reservoirs.
- A student draws a water-movement model with arrows and labels:
- Ocean → Clouds (evaporation) driven by Sun's energy
- Clouds → Land surface (precipitation) driven by gravity
- Land surface → Rivers (runoff) driven by gravity
- Rivers → Ocean (river flow) driven by gravity
- Land surface → Groundwater (infiltration/percolation) driven by gravity
The student also writes: "Energy enables movement but does not create water."
Which energy source mainly drives the movement of water from the ocean to the clouds in this model?
Answer: Sun's energy, because it provides energy for evaporation from the ocean
This skill involves using models to explain how energy moves water through Earth's water cycle. The Sun provides energy for evaporation, which transforms liquid water into water vapor that rises into the atmosphere. Gravity pulls water downward as precipitation (rain, snow), runoff across land surfaces, and infiltration into groundwater. To check your understanding, identify the direction of water movement: upward movement requires the Sun's energy, while downward movement is driven by gravity. A common misconception is thinking gravity can pull water upward or that the Sun directly moves liquid water downhill. In reality, water movement depends on both energy sources working together—the Sun lifts water up through evaporation, and gravity brings it back down through various pathways.
- A water-movement model shows this sequence of arrows:
Ocean → clouds (evaporation) → land surface (precipitation) → rivers (runoff) → ocean (river flow)
It also includes land surface → groundwater (infiltration) → rivers (groundwater flow).
The model identifies Sun's energy and gravity as the energy sources. Which statement best explains how the two energy sources work together in the model?
Remember: energy enables movement but does not create water.
Answer: Sun's energy mainly drives evaporation into the atmosphere, and gravity mainly drives water moving downward as precipitation, runoff, and groundwater flow.
This question requires using models to explain how energy moves water through the complete water cycle sequence. The Sun provides energy for evaporation, heating ocean water so it transforms to water vapor and rises into the atmosphere to form clouds. Gravity pulls water downward as precipitation (clouds to land), runoff (land to rivers), river flow (rivers to ocean), infiltration (land to groundwater), and groundwater flow (groundwater to rivers). To understand how both energy sources work together, trace the complete cycle: Sun energy lifts water up, gravity brings it down through multiple pathways. A misconception is thinking one energy source alone could drive the entire cycle or that energy creates water. Water movement depends on both energy sources working as partners - the Sun provides upward movement through evaporation, while gravity provides all downward movements, creating a continuous cycle.
- A student draws a water-movement model with reservoirs labeled ocean, clouds, land surface, rivers, and groundwater. Arrows show: ocean → clouds (evaporation), clouds → land surface (rain), land surface → rivers (runoff), rivers → ocean, and land surface → groundwater (infiltration). The student adds energy labels: "gravity drives evaporation" and "Sun's energy drives runoff downhill." Which claim about the energy sources is incorrect?
Answer: Sun's energy drives runoff downhill from land to rivers
Models help us understand how energy moves water through Earth's systems. The Sun provides energy that heats water, causing it to evaporate from oceans and other surfaces into the atmosphere. Gravity pulls water downward as precipitation falls from clouds, as runoff flows across land, and as groundwater seeps through soil. To identify which energy source drives a specific movement, check the direction: upward movement (like evaporation) requires the Sun's energy to overcome gravity, while downward movement relies on gravity's pull. A common misconception is confusing which energy source drives which movement—the Sun doesn't drive downhill flow, and gravity doesn't drive evaporation. Water movement in Earth's systems depends on both energy sources working together: the Sun lifts water into the atmosphere through evaporation, and gravity returns it to Earth's surface and oceans. Understanding these distinct roles helps us correctly interpret water cycle models.
- Use this labeled water-movement model:
- Ocean → Clouds: evaporation (Sun's energy)
- Clouds → Land surface: precipitation (gravity)
- Land surface → Rivers: runoff (gravity)
- Rivers → Ocean: river flow (gravity)
- Land surface → Groundwater: infiltration/percolation (gravity)
- Groundwater → Rivers: discharge (gravity)
Model note: "Energy enables movement but does not create water."
Prediction scenario: For one month, there is much less incoming Sun's energy (cooler temperatures and less sunlight), but gravity is unchanged.
Which change is most likely according to the model?
Answer: Less evaporation from the ocean to the clouds, so less water moves into clouds
Using models helps us understand how energy sources drive the movement of water in the water cycle. The Sun provides the energy needed for evaporation, turning liquid water into vapor that moves into the atmosphere. Gravity pulls water downward, causing precipitation to fall from clouds, runoff to flow over land, and groundwater to percolate into the soil. To check which energy source is at work, look at the direction of water movement: upward movements often rely on the Sun's energy, while downward movements are driven by gravity. A common misconception is that the Sun directly causes water to fall as rain, but actually, the Sun's role is in evaporation, while gravity handles the downward pull. Overall, the water cycle relies on both the Sun's energy and gravity working together to keep water moving continuously. Without either, parts of the cycle would stop, showing how interconnected these energy sources are.
- Use this water-movement model (arrows show movement) with energy sources labeled:
- Ocean → Clouds: evaporation (Sun's energy)
- Clouds → Land surface: precipitation (gravity)
- Land surface → Rivers: runoff (gravity)
- Rivers → Ocean: river flow (gravity)
- Land surface → Groundwater: infiltration/percolation (gravity)
- Groundwater → Rivers: discharge (gravity)
Statement included on the model: "Energy enables movement but does not create water."
Which comparison correctly matches each pathway to its main driving energy source?
Answer: Ocean → Clouds is driven mainly by Sun's energy; Land surface → Rivers is driven mainly by gravity
Using models helps us understand how energy sources drive the movement of water in the water cycle.

- A student builds a model with reservoirs ocean, clouds, land surface, rivers, and groundwater. The model includes arrows for: ocean → clouds (evaporation), clouds → land surface (precipitation), land surface → rivers (runoff), rivers → ocean (river flow), and land surface → groundwater (infiltration). The student correctly notes: "Energy enables movement but does not create water."
Which pairing of pathways is driven mainly by gravity in this model?
Answer: Runoff and infiltration
This question tests understanding of using models to explain how energy moves water through Earth's systems. The Sun provides energy for evaporation, which moves water upward into the atmosphere. Gravity pulls water downward as precipitation, runoff (surface water flowing downhill), infiltration (water soaking downward into soil), and river flow. To check which pathways share the same energy source, identify the movement direction: both runoff and infiltration involve downward movement driven by gravity. A common misconception is thinking the Sun drives all water movement, but gravity is responsible for all downward pathways. Water movement in Earth's systems depends on both energy sources working together in the cycle. Runoff and infiltration are both gravity-driven processes that move water downward from the land surface.
- Use this model of water movement and energy sources:
- Ocean → Clouds (evaporation) driven by Sun's energy
- Clouds → Land surface (precipitation) driven by gravity
- Land surface → Rivers (runoff) driven by gravity
- Rivers → Ocean driven by gravity
- Land surface → Groundwater driven by gravity
The model states: "Energy enables movement but does not create water."
If the amount of Sun's energy reaching Earth's surface decreased for a long time, which water movement would be most directly reduced first?
Answer: Evaporation from the ocean to form water vapor in clouds
This skill requires using models to explain how energy moves water between Earth's reservoirs. The Sun provides thermal energy for evaporation, converting liquid water into water vapor that rises from oceans to the atmosphere. Gravity pulls water downward through precipitation, runoff, river flow, and infiltration into groundwater. To predict impacts, identify which movements depend on each energy source: reduced solar energy would directly decrease evaporation rates since less heat means less water vapor formation. Students often think gravity-driven processes would be affected first, but these continue as long as water exists above ground level. The water cycle demonstrates how both energy sources work together—without sufficient solar energy for evaporation, less water would enter the atmosphere, eventually reducing all subsequent movements.

The model states: "Energy enables movement but does not create water."
Prediction: If the amount of Sun's energy reaching Earth's surface decreased for a long time, which water-movement pathway would most directly decrease first?
Answer: Ocean → clouds (evaporation), because less solar energy means less evaporation
This skill involves using models to explain how energy moves water through Earth's water cycle. The Sun provides energy for evaporation and atmospheric movement, directly heating water to change it from liquid to vapor. Gravity pulls water downward as precipitation, runoff, and groundwater flow, but gravity's strength doesn't change with sunlight levels. To check which process would be most affected by reduced solar energy, identify which movements directly depend on heat: evaporation requires the Sun's energy to transform liquid water to vapor. A common misconception is thinking less sunlight would weaken gravity, but gravity is constant regardless of solar energy. Water movement depends on both energy sources working together in the cycle, but evaporation is the process most directly dependent on solar energy input.
- Two pathways in a water-movement model are labeled: Pathway 1: ocean → clouds (evaporation). Pathway 2: land surface → rivers → ocean (runoff and river flow). The model identifies Sun's energy and gravity as the drivers. Which comparison correctly matches each pathway to its main energy source?
Answer: Pathway 1: Sun's energy; Pathway 2: gravity
Models help us understand how energy moves water through Earth's systems. The Sun provides energy that heats water, causing it to evaporate from oceans and other surfaces into the atmosphere. Gravity pulls water downward as precipitation falls from clouds, as runoff flows across land, and as groundwater seeps through soil. To identify which energy source drives a specific movement, check the direction: upward movement (like evaporation) requires the Sun's energy to overcome gravity, while downward movement relies on gravity's pull. A common misconception is thinking all pathways use the same energy source—ocean to clouds requires solar energy for evaporation, while land to ocean relies on gravity for downhill flow. Water movement in Earth's systems depends on both energy sources working together: the Sun lifts water into the atmosphere through evaporation, and gravity returns it to Earth's surface and oceans. Each pathway in the water cycle has a primary energy driver based on whether water moves up or down.
- A water-movement model includes reservoirs: ocean, clouds, land surface, rivers, and groundwater.

The model states: "Energy enables movement but does not create water."
Which claim about water movement is supported by the model?
Answer: Sun's energy mainly drives evaporation, and gravity mainly drives runoff and infiltration
This skill involves using models to explain how energy moves water through Earth's water cycle. The Sun provides energy for evaporation and atmospheric movement, heating water until molecules escape as vapor. Gravity pulls water downward as precipitation, runoff, and groundwater flow, moving water from higher to lower elevations like from land to rivers. To check which energy drives each process, identify the movement direction: upward movements like evaporation need the Sun's energy, while downward movements like runoff and infiltration use gravity. A common misconception is thinking water vapor rises because gravity pulls it up, but vapor rises because solar energy gives molecules enough energy to overcome gravity. Water movement depends on both energy sources working together in the cycle, with distinct roles for each.
- A student draws a water-movement model with these labeled reservoirs: ocean, clouds, land surface, rivers, groundwater. The arrows are:
- Ocean → Clouds (evaporation)
- Clouds → Land surface (precipitation)
- Land surface → Rivers (runoff)
- Rivers → Ocean (river flow)
- Land surface → Groundwater (infiltration)
The student labels Sun's energy as the driver for evaporation and labels gravity as the driver for precipitation and runoff. Which statement is supported by this model?
Answer: Runoff from land to rivers is mainly driven by gravity pulling water downhill
Using models helps us understand how energy sources drive the movement of water in Earth's systems. The Sun supplies the energy that causes water to evaporate from surfaces like oceans and lakes, turning it into vapor that rises into the atmosphere. Gravity acts to pull water back down to Earth in forms such as rain or snow, and it also drives the flow of water over land as runoff and through the ground as groundwater. To check which energy source is at work, look at the direction of water movement: upward movements like evaporation are typically powered by the Sun's heat, while downward or downhill flows are influenced by gravity. A common misconception is that the Sun directly causes water to fall as precipitation, but actually, the Sun's role is in lifting water up, while gravity handles the downward pull. In the water cycle, both the Sun's energy and gravity are essential, working together to keep water circulating through various reservoirs on Earth. Without either, the cycle would not function as it does, demonstrating their interdependent roles in moving water globally.
- A student summarizes a water-movement model with energy sources:
- Sun's energy drives ocean → clouds (evaporation).
- Gravity drives clouds → land surface (precipitation), land surface → rivers (runoff), rivers → ocean (river flow), and land surface → groundwater (infiltration).
The model includes the statement: "Energy enables movement but does not create water."
Which claim is supported by the model?
Answer: Water can move from clouds to the land surface because gravity pulls it downward
This skill focuses on using models to explain how energy moves water between Earth's reservoirs. The Sun provides thermal energy that drives evaporation, transforming liquid water into water vapor that rises from oceans to clouds. Gravity pulls water downward as precipitation from clouds to land, as well as during runoff and infiltration processes. To evaluate claims, check if they match the model's energy sources and movement directions—gravity indeed pulls precipitation downward from clouds to land surface. A key misconception is thinking energy sources create new water, when actually they only enable movement of existing water molecules. The water cycle demonstrates how solar energy and gravity work together to continuously move Earth's fixed water supply between different reservoirs.
- Consider this water-movement model (arrows show pathways):
- Ocean → Clouds (evaporation) driven by Sun's energy
- Clouds → Land surface (precipitation) driven by gravity
- Land surface → Rivers (runoff) driven by gravity
- Rivers → Ocean driven by gravity
- Land surface → Groundwater driven by gravity
The model notes: "Energy enables movement but does not create water."
Which comparison correctly matches each pathway to its main driving energy source?
Answer: Evaporation (ocean → clouds) is driven by Sun's energy; runoff (land → rivers) is driven by gravity
This skill focuses on using models to explain how energy moves water between Earth's reservoirs. The Sun provides thermal energy that causes evaporation, transforming liquid water into water vapor that rises from oceans to form clouds. Gravity pulls water downward during precipitation, runoff from land to rivers, and infiltration into groundwater systems. When analyzing water movement, match the direction to the energy source: upward movement (like evaporation) requires the Sun's energy, while downward movement (like runoff) is driven by gravity. Many students mistakenly think gravity powers evaporation or that the Sun moves water downhill. The water cycle demonstrates how these two energy sources work in complementary ways—the Sun provides energy to lift water up, and gravity provides the force to bring it back down.
- A model includes reservoirs ocean, clouds, land surface, rivers, and groundwater. Arrows show ocean → clouds (evaporation), clouds → land surface (rain), land surface → rivers (runoff), and rivers → ocean. A student claims: "Because water is always moving in a cycle, it cannot stay in one reservoir." Which statement best evaluates the claim using the model and the idea that energy enables movement but does not create water?
Answer: The claim is not supported; water can be stored in reservoirs like the ocean or groundwater before moving again
Models help us understand how energy moves water through Earth's systems. The Sun provides energy that heats water, causing it to evaporate from oceans and other surfaces into the atmosphere. Gravity pulls water downward as precipitation falls from clouds, as runoff flows across land, and as groundwater seeps through soil. To identify which energy source drives a specific movement, check the direction: upward movement (like evaporation) requires the Sun's energy to overcome gravity, while downward movement relies on gravity's pull. A common misconception is thinking water must always be actively moving—water can be stored in reservoirs like oceans, lakes, or underground aquifers for varying periods before moving again. Water movement in Earth's systems depends on both energy sources working together: the Sun lifts water into the atmosphere through evaporation, and gravity returns it to Earth's surface and oceans. The water cycle includes both movement between reservoirs and storage within them.
- Refer to this model (reservoirs: ocean, clouds, land surface, rivers, groundwater). Arrows and labels:
- Ocean → Clouds: evaporation (Sun's energy)
- Clouds → Land surface: precipitation (gravity)
- Land surface → Rivers: runoff (gravity)
- Land surface → Groundwater: infiltration (gravity)
- Groundwater → Rivers: discharge (gravity)
- Rivers → Ocean: river flow (gravity)
Model note: "Energy enables movement but does not create water."
A student points to the arrow Land surface → Rivers and says, "That arrow happens mainly because the Sun pushes water across the ground."
Which evaluation best fits the model?
Answer: Incorrect; runoff is mainly driven by gravity pulling water downhill on the land surface
Using models helps us understand how energy sources drive the movement of water in the water cycle. The Sun provides the energy needed for evaporation, turning liquid water into vapor that moves into the atmosphere. Gravity pulls water downward, causing precipitation to fall from clouds, runoff to flow over land, and groundwater to percolate into the soil. To check which energy source is at work, look at the direction of water movement: upward movements often rely on the Sun's energy, while downward movements are driven by gravity. A common misconception is that the Sun directly causes water to fall as rain, but actually, the Sun's role is in evaporation, while gravity handles the downward pull. Overall, the water cycle relies on both the Sun's energy and gravity working together to keep water moving continuously.

- Land surface → Rivers (runoff) driven by gravity
- Rivers → Ocean driven by gravity
- Land surface → Groundwater driven by gravity
The model includes: "Energy enables movement but does not create water."
Which statement set includes 2 statements that are supported by the model?
Answer: Evaporation is driven by Sun's energy; precipitation is driven by gravity
This skill focuses on using models to explain how energy moves water through Earth's water cycle. The Sun provides energy for evaporation, heating ocean water until it transforms into water vapor that rises to form clouds. Gravity pulls water downward during precipitation from clouds to land surface, as well as during runoff, river flow, and infiltration. To verify statements, check if they correctly match each pathway with its energy source according to the model. A common misconception is thinking all water movement depends on just one energy source, when actually the Sun drives upward movement while gravity drives downward movement. The water cycle operates through this partnership: solar energy lifts water up through evaporation, and gravity returns it to Earth through various downward pathways.
- A student's model includes reservoirs (ocean, clouds, land surface, rivers, groundwater) and arrows:
- Ocean → Clouds labeled "evaporation"
- Clouds → Land surface labeled "precipitation"
- Land surface → Rivers labeled "runoff"
- Land surface → Groundwater labeled "infiltration"
The student tries to label the energy sources but makes one mistake:
- Evaporation: gravity
- Precipitation: gravity
- Runoff: gravity
- Infiltration: gravity
The student also writes: "Energy enables movement but does not create water."
Which pathway has the energy source labeled incorrectly?
Answer: Ocean → Clouds (evaporation)
This skill involves using models to explain how energy moves water through different pathways in the water cycle. The Sun provides energy for evaporation, which requires heat to change liquid water into water vapor that rises into the atmosphere. Gravity pulls water downward in all other pathways: precipitation from clouds, runoff across land, river flow, and infiltration into groundwater. To identify incorrect labels, check if the movement direction matches the energy source—upward movement needs the Sun's energy, not gravity. A common error is labeling evaporation as gravity-driven, when actually gravity cannot pull water upward against its own force. Understanding these energy sources helps explain why water continuously cycles between Earth's reservoirs through predictable pathways.
- A model shows these reservoirs and arrows (with energy sources labeled): ocean, clouds, land surface, rivers, groundwater.
