Weathering and Erosion Quiz

Which of the following is the process of breaking down rocks into smaller pieces?

• Erosion

• Deposition

• Weathering

• Compaction

What are the two main types of weathering?

• Wind and water

• Heat and cold

• Physical and chemical

• Erosion and deposition

Which of the following is an example of physical weathering?

• Oxidation of iron

• Acid rain dissolving limestone

• Frost wedging

• Hydrolysis of feldspar

Frost wedging is most effective in areas with:

• High temperatures and low humidity

• Frequent freeze-thaw cycles

• Constant warm temperatures and high rainfall

• Arid climates with strong winds

The abrasion of rocks by wind-blown sand is an example of:

• Chemical weathering

• Biological weathering

• Physical weathering

• Hydrolysis

What is the process where plant roots grow into cracks in rocks and cause them to break apart?

• Oxidation

• Root wedging

• Abrasion

• Exfoliation

Which of the following is NOT a factor that affects the rate of physical weathering?

• Climate

• Rock type

• Surface area

• Chemical composition

Chemical weathering involves the:

• Physical breakdown of rocks

• Change in the chemical composition of rocks

• Transportation of weathered material

• Deposition of sediments

The reaction of minerals with oxygen is called:

• Hydrolysis

• Carbonation

• Oxidation

• Dissolution

Which type of rock is most susceptible to weathering by acid rain?

• Granite

• Sandstone

• Limestone

• Basalt
