Weathering, Erosion, and Mass Movement test

1.If a mineral changes to a different type it has experienced

• erosion
• physical weathering
• chemical weathering
• Transportation

2.What are the four agents of erosion?

• gravity, soil, landslides, water
• wind, water, landslides, organisms
• organisms, glaciers, wind, water
• glaciers, gravity, air, soil

3. Which layer of soil would you find the largest amount of organic material?

• A horizon
• B horizon
• C horizon
• O horizon

4. Soil made from the bedrock that lies beneath it is

• transported soil
• eroded soil
• residual soil
• weathered soil

5. Soil scientists study the layers of soil that together are called

• transported soil
• residual soil
• soil horizons
• a soil profile

6. What happens when pressure is released from a rock?

• The cracks will disappear
• The cracks will shrink, but not disappear entirely
• The cracks will expand
• The cracks will not change

7. Which of the following is NOT a way that water can cause chemical weathering?

• Act as a medium for another chemical
• Erode small pieces of the rock
• Dissolve minerals
• Break down large molecules into smaller ones

8. What type of weathering most likely caused this?

• Mechanical Weathering
• Chemical weathering
• Mechanical and Chemical weathering
• Physical and chemical weathering

9. Why do we need wind barriers?

• To prevent wind erosion from hitting structures and wearing them down
• To protect trees from being blown over by wind
• To prevent sediment from being blown around and to protect the ground
• All of the above

10. What effect do organisms have on soils?

• They add nutrients to the soil
• They provide a passage for air and water
• They break up the pieces of soil into finer pieces
• All of the above
