Weathering Types

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 rocks weaken then break down due to chemical changes in the composition of the rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:

• ice wedging
• chemical weathering
• acid rain
• abrasion

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging
• acid rain
• permeability
• abrasion

A piece of sandstone changing color (from brown to rusty red) from exposure to water and air is an example of:

• mechanical weathering
• chemical weathering

The formation of large cracks in the face of a mountain from ice wedging is an example of:

• mechanical weathering
• chemical weathering

Exposure to rain and oxygen causes the metal minerals in rocks to rust and fall apart.  This is an example of:

• mechanical weathering
• chemical weathering

When rocks are broken down into smaller pieces

• erosion
• weathering
• sediment

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.
