Rocks Pre Test

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 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.

Rocks along a riverbed that are smoothed from continuously moving water and sediment rubbing against them 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

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
