Surface Processes Semester Test Review

How does plant life (vegetation) help keep slopes stable and reduce erosion?

• Roots hold the soil in place, reducing erosion and helping prevent landslides.

• Plants absorb excess water, which increases soil moisture and promotes erosion.

• Vegetation provides shade, which cools the soil and prevents erosion.

• Roots of plants grow deep into the ground, making the soil more prone to erosion.

What do you call a long, narrow sea inlet with steep sides, formed when a glacier carves out a U-shaped valley and the sea floods it?

• Fjord

• Bay

• Cove

• Estuary

Use the soil texture triangle to find the soil type based on the percentage of sand, silt, and clay.

• Be prepared to locate a soil type by using the intersecting lines from given percentages.

• Identify the soil type based solely on the color of the soil.

• Determine the soil type by measuring the soil's temperature.

• Classify the soil type using only the smell of the soil.

What is the name for the pile of rocks, dirt, and debris left behind after a glacier melts?

• Moraine

• Drumlin

• Erratic

What do you call a bowl-shaped dip in the mountains formed by glacial erosion?
