Earth Science Review

Three types of physical weather are: Rapidly moving water, ice wedging, and plant roots

___________ weathering: Decomposes, or decays, rocks and minerals.

What is happening in the picture?

A process in which rocks change into other materials

Physical Weathering: ocean waves can cause weathering when they crash into rock

Mechanical Weathering is the breaking of larger rocks into smaller pieces of rock.

What are the forces that cause Erosion?

Weathering or Erosion? The water in this river made its way through and formed the canyon.

The process of rock breaking apart without changing their chemical composition

The leading cause of chemical weather is:

_________ occurs when rocks and sediment are moved from one place to another

The breakdown of rocks and minerals by changing their chemical composition

When sediments are picked up due to erosion, they are deposited or dropped off in another location

What is happening in this picture

Plants cause erosion when their roots grab dirt and push it away.
