Example Questions

Example Question #1 : Use A Model To Represent The Shapes Of Land In An Area

In what way(s) can you represent the shapes and kinds of land in an area in a realistic way?

Possible Answers:

Build a model, sketch a drawing, or make a map

You can use your body to make the shape of the land

There is no way to represent the shape of the land

Create a song and dance about landforms in your area

Correct answer:

Build a model, sketch a drawing, or make a map

Explanation:

The most realistic and reasonable answer choice for representing the shapes and kinds of land in an area would be to build a model, sketch a drawing, or make a map. These activities would be good representations of the earth. A model can be made out of clay or loose materials to look three-dimensional, a map is an accurate way to show people the land, and a drawing can be a great interpretation of how you see the shapes.

Example Question #2 : Use A Model To Represent The Shapes Of Land In An Area

Maps show where things are located. You can map the shapes and kinds of land in any area.

Possible Answers:

True

False

Correct answer:

True

Explanation:

This statement is true. A map does show where things are and can help people locate places and landforms. Maps can represent mountains, deserts, valleys, and other landforms. Different kinds of maps even are three-dimensional and have texture to help you feel what the landforms are like.

Example Question #3 : Use A Model To Represent The Shapes Of Land In An Area

Which material would be the best to use to create a model of a mountain?

Possible Answers:

Water

Dirt

Modeling clay

Sand

Correct answer:

Modeling clay

Explanation:

The best material to use to create a model of a mountain needs to be something moldable, sturdy, and able to hold its shape. Modeling clay would meet all of these characteristics. The clay could be pressed into a mountain shape. It could even be painted or have other materials added to it to make it look more realistic.

Example Question #4 : Use A Model To Represent The Shapes Of Land In An Area

What does the term landform mean? Example: We were each assigned a landform, and we have to make a model. I was assigned a volcano and am so excited!

Possible Answers:

A human-made structure

A form that must be filled out to purchase a home

A cover that is placed over different parts of the land for protection

A natural feature of the Earth's surface

Correct answer:

A natural feature of the Earth's surface

Explanation:

The term landform is used in both science and geography. A landform is a naturally made feature of the Earth's surface. In the example, the student was assigned a volcano as a landform. Other landform examples include mountains, hills, valleys, and canyons.

Example Question #5 : Use A Model To Represent The Shapes Of Land In An Area

What is a characteristic of Earth’s landforms?

Possible Answers:

There are no characteristics of landforms that we know of.

All landforms are nearly identical, there is very little difference between them.

Landforms were all made by humans and planned.

Each landform was created through natural processes over time.

Correct answer:

Each landform was created through natural processes over time.

Explanation:

A characteristic that all of Earth's landforms have in common is that they were created over time through natural processes. Landforms are changed Earth due to the process of weathering and erosion. As the Earth is changed, existing landforms change, and new landforms are created.

Example Question #6 : Use A Model To Represent The Shapes Of Land In An Area

LeBron has to make a model of the shapes of the land in his area. He gets modeling clay, dirt, grass, rocks, and a tray. Which item should he choose to help make his model accurate?

 

Possible Answers:

A drawing his brother made

A globe

A photo of Mount Everest

A detailed local map

Correct answer:

A detailed local map

Explanation:

Maps are a perfect way to show the shapes of the land that is in an area. By mapping the land, people can see the shape, size, and how the surrounding bodies of water are shaped as well. If the map is local and, detailed LeBron can use this as a plan to follow when making the model.

 

Example Question #7 : Use A Model To Represent The Shapes Of Land In An Area

Dejah's class is creating models to represent the shapes of landforms in different areas. She was assigned to a mountain.

Which material(s) would be the best to use to represent a mountain?

Possible Answers:

Water, rocks, sticks, and ice

Leaves, mud, sticks, and sand

Ice, dirt, water, and leaves

Rocks, dirt, sand, and water

Correct answer:

Rocks, dirt, sand, and water

Explanation:

The best materials to select would be rocks, dirt, sand, and water. Mountains are usually tall, jagged, and rough. They are solids and have a defined structure. Dejah could wet the dirt and sand and form it into a mountain shape like she would with a sandcastle. Then she can place rocks on the outside to demonstrate the texture of a mountain.

 

Example Question #8 : Use A Model To Represent The Shapes Of Land In An Area

Maps do not show the shape of landforms or land in an area, so they are not useful when making a model.

 

Possible Answers:

True

False

Correct answer:

False

Explanation:

Maps are a perfect way to show the shapes and kinds of land or landforms that are in an area. By mapping the land, people can see the shape, size, and how the surrounding bodies of water are shaped as well. Making a map is a clear way to demonstrate details about the land.

 

Example Question #9 : Use A Model To Represent The Shapes Of Land In An Area

Which answer choice is NOT a landform?

Possible Answers:

Skyscraper

Canyon

Mountain

Volcano

Correct answer:

Skyscraper

Explanation:

Three of the listed answer choices are naturally occurring landforms that would be mapped or could be modeled; a mountain, volcano, and canyon. These are all formed naturally from rocks and earth over many years through weathering and erosion. A skyscraper is a human-made building that is not a landform or naturally occurring.

Example Question #61 : Earth And Space Science

What is NOT a characteristic of Earth’s landforms?

Possible Answers:

Landforms can be modeled and mapped.

Landforms were all made by humans and planned.

Landforms can be found all over the world.

Landforms were created by weathering and erosion.

Correct answer:

Landforms were all made by humans and planned.

Explanation:

Characteristics that all of Earth's landforms have in common is that they were created over time through natural processes, they are due to the process of weathering and erosion, and found all over the world. As the Earth is changed, existing landforms change, and new landforms are created. Landforms were NOT all made by humans and planned.
