Earth Science Mass Movements

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

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

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

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

Which is NOT a type of mass movement?

• landslide
• slump
• mudflow
• windstorm

This is a picture of a

• slump
• creep
• mudflow
