What type of weathering involves the physical breakdown of rocks?

• Mechanical

• Ice Wedging

• Roots

• Chemical

• Carbonic Acid

Is this structure caused by mechanical or chemical weathering?

• Mechanical Weathering

• Chemical Weathering

plants produce weak acids that slowly dissolve the rock they are growing on

• chemical weathering

• mechanical weathering

• erosion

• deposition

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.

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
