Weathering, Erosion, and Deposition

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

• weathering
• erosion
• deposition
• jackhammering

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

• weathering
• erosion
• deposition
• dumptruck

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.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

How is mechanical weathering different from chemical weathering?

• Chemical weathering happens over much shorter time frame than mechanical weathering.
• Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.
• Chemical weathering occurs only in tropical climates; mechanical weathering occurs only in cool climates.
• Chemical weathering occurs only in the mountains; mechanical weathering occurs only on flat land.

Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:

• mechanical weathering
• chemical weathering

A metal statue slowly turning green after years of being outside is an example of:

• mechanical weathering
• chemical weathering
