Sci 8 Earth's Surface Test Review

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

• weathering
• erosion
• deposition
• jackhammering

This type of weathering occurs when rock is broken down into smaller pieces of rock with no change in composition.

• physical 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

How is physical weathering different from chemical weathering?

• Chemical weathering happens over much shorter time frame than physical weathering.

• Chemical weathering changes the chemical composition of rocks; physical weathering does not.

• Chemical weathering occurs only in tropical climates; physical weathering occurs only in cool climates.

• Chemical weathering occurs only in the mountains; physical weathering occurs only on flat land.

This type of weathering occurs when rocks weaken and break down due to chemical changes in the composition of the rock.

• physical weathering

• chemical weathering

• erosion weathering

• deposition

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

• physical weathering

• chemical weathering

Potholes forming in the road after a cold winter is an example of:

• physical weathering

• chemical weathering

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

• physical weathering

• chemical weathering

Rocks along a riverbed that are smoothed from continuously moving water and sediment rubbing against them is an example of:

• physical weathering

• chemical weathering

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

• physical weathering

• chemical weathering
