Chemical weathering typically takes place in ____ climates, whereas mechanical weathering typically takes place in ____ climates.

• warm; cold

• dry; humid

• humid; dry

• cold; warm

What is mechanical weathering?

• Chemical weathering involves the alteration of minerals in rocks.
• Mechanical weathering is the physical breakdown of rocks into smaller fragments.
• Mechanical weathering is the process of rocks melting due to heat.
• Mechanical weathering is the transportation of sediments by wind or water.

What is the process called when rocks expand during the day due to heat and contract at night as temperatures drop. This repeated cycle creates stress within the rock, causing layers to separate and eventually break off.

• Chemical weathering
• Exfoliation

• Oxidation

• Frost Wedging

The following image shows the process of frost wedging, which is an example of what type of weathering due to what?

• Mechanical weathering due to temperature.

• Chemical weathering due to Acid Rain.

• Chemical weathering due to Oxidation.

• Mechanical weathering due to pressure.
