Factors Affecting Weathering

Which process is responsible for changing the composition of rock?

• erosion

• abrasion

• chemical weathering

• mechanical weathering

Which process is defined as breaking down rocks into smaller pieces without changing the rocks' compositions?

• erosion

• abrasion

• chemical weathering

• mechanical weathering

Which condition leads to a slower rate of weathering?

• porous rocks

• cold climates

• hard minerals

• high temperatures

Which describes sand?

• fine-grained

• retains water

• water drains quickly

• good for growing crops

Which describes how weathering and erosion are different?

• Weathering is caused by water.

• Erosion is caused by wind and ice.

• Erosion transports sediments.

• Weathering is a natural process.

Which is one factor of rock types that affects the rate of weathering?

• porosity

• moisture

• temperature

• mineral color

Which climate favors mechanical weathering?

• dry climate

• cold climate

• warm climate

• desert climate

Which describes a climate effect on the rate of weathering?

• Cold climates favor mechanical weathering.

• Chemical reactions occur slower at higher temperatures.

• Lower precipitation levels lead to more chemical reactions

• The chemical reaction rates of minerals are not impacted by temperature.
