What is weathering?

• A) The process of moving rocks from one place to another

• B) The breaking down of rocks into smaller pieces

• C) The creation of new rocks from lava

• D) The melting of ice into water

What is the process of moving sediments from location to another?

• Deposition

• Erosion

• Weathering

• Compaction

What is sediment?

• bits of rock, sand, and silt caused by the weathering of rocks
• the top layer of the soil
• decaying plant or animal material

• Deposition

The natural chemical or physical processes that breaks down rock on Earth's surface.

• weathering
• erosion
• deposition
• jackhammering

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.
