CP 2 Review

1. 1. The photograph shows several sand dunes in a desert. How were these sand dunes formed?

• A. Glaciers dragged the sand into piles thousands of years ago.

• B. Wind and rains brought the sand in from all around the desert

• C. The sand was built up into layers of sedimentary rock.

• D. The sand was carried by rivers and collected in the desert.

2. Heavy, soaking rains over long periods of time are the most common causes of landslides. The picture below shows a recent landslide in a mountain area. After looking at the picture, what observation about landslides can you make?

• A. A landslide is an example of weathering. Landslides occur when Earth's surface is broken down into smaller pieces of rock and soil.

• B. A landslide is an example of weathering. Landslides occur when pieces of rock and soil completely disappear from Earth's surface.

• C. A landslide is an example of erosion. Landslides add new features to Earth's surface made from rock and soil

• D. A landslide is an example of erosion. Landslides build up piles of piles of rock and soil on Earth's surface.

3. Earth's surface is always changing to create new landforms over time. Rock can be broken down into smaller pieces through many different processes. The diagram below shows the process of the breakdown of rock and the carrying away of the loose sediments. What are two likely ways that rock on the mountain is broken down?

• A. The rock is broken down when sediment builds up between the rocks.

• B. The rock is broken down when the wind blows materials against the rocks.

• C. The rock is broken down when cracks within the rocks freeze and thaw.

• D. The rock is broken down when high temperatures cause the rocks to melt.

• E. The rock is broken down when moving tectonic plates pull the rocks apart.

4. Fourth graders are studying how glaciers change landscapes creating new landforms over time. Student groups make claims about how glaciers form valleys over thousands of years.

Group 1: "Glaciers are slow-moving bodies of water that deposit rocks and loose sediments into a valley."

Group 2: "Glaciers are fast-moving bodies of water that deposit rocks and loose sediment into a valley."

Group 3: "Glaciers are fast-moving sheets of ice that move rocks and loose sediments out of an area to form a valley."

Group 4: "Glaciers are slow-moving sheets of ice that move rocks and loose sediments out of an area to form a valley."

Which group's description of how glaciers form valleys is correct?

• A. Group 1

• B. Group 2

• C. Group 3

• D. Group 4

• A. 1 and 2

• B. 1 and 3

• C. 2 and 3

• D. 1 and 4

6. A tree begins to grow on a mountain in a dry area with a warm climate. After many years, a pile of small rock pieces forms at the bottom of the mountain. The pictures illustrate the tree and mountain over time. What most likely caused the rock to break into pieces?

• A. Animals dug deep into the rock.

• B. Flowing water broke apart the rock.

• C. Growing tree roots broke apart the rock.

• D. Water froze and cracked the inside of the rock.

• A. Most ocean trenches connect two different continents together.

• B. Most ocean trenches are located near the edge of a continent where it meets the ocean.

• C. Most ocean trenches are located far away from the continents in the middle of an ocean.
