Why do farmers plant a cover crop?
What is the cover crop reduces the amount of soil erosion?
200
The process of breaking down rock into smaller pieces.

What is just below the water's surface?
200
During this type of weathering, the actual minerals that make up the rocks change.
What is chemical weathering?
200
What causes sand dunes to form?
What is wind?
200
Would rocks on the Moon weather faster or slower than rocks on Earth?
Rocks on the moon would weather slower because the Moon has no surface water, plants, or atmosphere containing oxygen.
300
The process by which soil and sediments are transferred from one location to another (usually by wind, water, ice, and gravity).
What is erosion?
300
When will the amplitude of ocean waves be the smallest?
What is on a calm day?
300
Plant roots grow into cracks in rocks and make the cracks larger. What is happening?
What is mechanical weathering?
300
What kind of weather would you expect if you went to the beach and saw waves that are larger than normal?
What is a storm or high winds?
300
How were the canyons in Badlands National Park formed?

400
Solid particles that are moved from one location to another.
What are sediments?
400
One beach has white sand and one beach has black sand. The color of sand on a beach depends on...
What is the source of the sand and rock?
400
What is the difference between erosion and weathering?
Erosion involves the movement of materials from one place to another.
400
A longshore current can move sediment from the shoreline to an area in the water. What kind of landform does this movement cause? (Hint: It is much shallower than the area around it)
What is a sandbar?
400

500
List four different types of landforms.
Possible answers: 1. canyons 2. lakes 3. rivers 4. plateaus 5. mountains 6. plains
500
What is happening when iron oxide (a greenish coloring) forms on the side of a rock?
What is chemical weathering?
500
Name two forces that change coastal landforms and give an example of each.
1. Waves- Waves carry sediments that wear down landforms. 2. Wind- Wind can blow loose sand into piles called dunes.
500
Explain why a river deposits heavier sediments first and lighter sediments later as it flows along.
Heavier sediments are deposited first because the water has more energy and can carry them before it slows down. When the water slows down, lighter sediments are deposited.
