Earth Processes Mid-term/IA2 Review

Front

What is a levee?

Back

A levee is a thick wall, often made of dirt, used to protect towns from floods.

Front

How can a levee be improved to protect against higher flood waters?

Back

The levee could be designed to be taller.

Front

What is weathering?

Back

Weathering is a destructive process where rocks, soil, roads, and buildings are broken down into smaller parts.

Front

What is erosion?

Back

Erosion is the movement of materials from one place to another by natural methods, which can be constructive (like forming a delta) or destructive (like a landslide).

Front

What weather hazard can wetlands help reduce?

Back

Wetlands can help reduce the effects of floods.

Front

What is the common agent of erosion in mudslides, landslides, and creep?

Back

The common agent of erosion in these processes is gravity.

Front

What materials can levees be made from?

Back

Levees can be made from dirt, stronger materials, or waterproof materials.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down materials, while erosion moves them from one place to another.

Front

What role do wetlands play in the environment?

Back

Wetlands absorb large amounts of water and help mitigate flooding.

Front

What natural forces can cause erosion?

Back

Natural forces that can cause erosion include water, ice, wind, and gravity.
