Examples of Types of Weathering

Roots break apart a side walk

• Chemical weathering

• Physical weathering

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 does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place

• makes the rocks last longer

• expands cracks and breaks rocks

• causes rocks to fall in landslides

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.

• chemical weathering

• mechanical weathering

• erosion

• deposition
