Middle School Earth and Space Science › Trace Water Cycle
Use the water-cycle model. The arrows show multiple possible pathways, so there is no single correct route.
Model (arrows show possible moves):
- Ocean → Atmosphere
- Ocean → Surface water
- Atmosphere → Surface water
- Atmosphere → Ice
- Surface water → Atmosphere
- Surface water → Groundwater
- Groundwater → Surface water
- Groundwater → Ocean
- Ice → Surface water
Which route includes groundwater movement (passes through groundwater) and follows the arrows?
Ocean → Groundwater → Atmosphere → Surface water
Atmosphere → Ice → Surface water → Groundwater
Surface water → Groundwater → Ocean → Atmosphere
Ice → Groundwater → Surface water → Atmosphere
Explanation
Tracing water through the water cycle involves following the possible paths a water droplet can take from one reservoir to another. Water moves among various reservoirs such as oceans, atmosphere, surface water, groundwater, and ice. There are multiple pathways possible because arrows in the model show different directions water can flow. To check if a path is possible, follow the arrows step by step from the starting point to see if each move is allowed. A common misconception is that water follows a single fixed path, but in reality, it can take various routes depending on conditions. The water cycle is dynamic, allowing water to cycle through different reservoirs in flexible ways. It is not a single loop but a network of interconnected paths.
Use the water-cycle model below. The arrows show that water can move between reservoirs in more than one way, and the cycle has no single correct route.
Model (arrows show possible moves):
- Ocean → Atmosphere
- Ocean → Surface water
- Atmosphere → Surface water
- Atmosphere → Ice
- Surface water → Atmosphere
- Surface water → Groundwater
- Groundwater → Surface water
- Groundwater → Ocean
- Ice → Surface water
A water droplet is currently in surface water (a river). Which path could the droplet take next and then after that, following the arrows?
Surface water → Ice → Atmosphere
Surface water → Atmosphere → Groundwater
Surface water → Groundwater → Ocean
Surface water → Ocean → Ice

The water cycle is dynamic, allowing water to cycle through different reservoirs in flexible ways. It is not a single loop but a network of interconnected paths.
Refer to the model. Because the arrows branch, water can follow many different paths and may stay in reservoirs for different lengths of time; the cycle has no single correct route.

Explanation
Tracing water through the water cycle involves following the possible movements of water from one location to another based on a model's arrows. Water moves among many reservoirs, such as the ocean, atmosphere, surface water, groundwater, and ice. Multiple pathways are possible because water can take different routes depending on the available connections. To check a path, follow the arrows step by step to ensure each move is directly linked by an arrow in the model. A common misconception is that water follows a single fixed path, but in reality, it can branch and loop in various ways. The water cycle is dynamic, allowing water to revisit reservoirs or skip others entirely. Overall, it is flexible and not confined to a single loop, reflecting the natural variability in water movement.
Refer to the water-cycle model. The arrows show alternative routes, so different droplets can follow different paths and there is no single correct sequence.
Model (arrows show possible moves):
- Ocean → Atmosphere
- Ocean → Surface water
- Atmosphere → Surface water
- Atmosphere → Ice
- Surface water → Atmosphere
- Surface water → Groundwater
- Groundwater → Surface water
- Groundwater → Ocean
- Ice → Surface water
Which statement about water movement is supported by the model? (Select ONE.)
Water can move from surface water into groundwater and later return to surface water.
Water must always move from the ocean to the atmosphere before it can reach surface water.
Water disappears after it leaves the atmosphere because the model has no arrow back to the ocean.
Once water enters groundwater, it cannot return to surface water.

Look at the water-cycle model. The branching arrows show that water can take different routes and does not have a single starting or ending point.

- Groundwater → Surface water
- Groundwater → Ocean
- Ice → Surface water
A student says: “If a droplet enters the ice reservoir, it will stay there forever because ice is the end of the cycle.” Which response best matches the model?
The claim is supported because the only real cycle is ocean → ocean, and ice is outside the cycle.
The claim is not supported because the model shows ice can move to surface water, so ice is not a permanent endpoint.
The claim matches the model because ice has no arrow leaving it.
The claim is supported because water only moves through the cycle when humans pump it out of ice.
