CCA review for weathering erosion and deposition and watersheds

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

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

How might a weathered mountain appear different than an unweathered mountain?

• Weathered mountain would be taller.
• Weathered mountain would be rounder and less jagged.
• Weathered mountain would be more jagged and less rounded.
• Weathered mountain would have no trees.

Lichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This 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 of the following is an example of chemical weathering?

• Acid rain dissolving limestone
• roots breaking into concrete
• paper being ripped
• Water running over rocks

Which agents break down earth materials?

• wind only

• earthquakes and gravity

• ice and 007

• wind, water, ice, and gravity

A glacier is a large mass of

• water
