Weathering and Erosion Quiz

What is an example of chemical weathering?

• Formation of rust on iron

• Formation of snow

• Growth of plants

• Erosion of mountains

How does acid rain contribute to chemical weathering?

• Acid rain has no effect on chemical weathering

• Acid rain only affects the color of rocks, not their chemical composition

• Acid rain reacts with minerals in rocks, causing them to break down and dissolve.

• Acid rain causes rocks to become stronger and more resistant to weathering

What is an example of physical weathering?

• Chemical reaction

• Plant roots breaking rocks

• Freeze-thaw cycles

• Volcanic eruption

How does frost action contribute to physical weathering?

• Frost action causes rocks to break apart due to the expansion of water when it freezes.

• Frost action causes rocks to melt and disappear

• Frost action has no impact on physical weathering

• Frost action makes rocks stronger and more resistant to weathering

How does water contribute to erosion?

• By carrying away soil and rock particles through the process of water erosion.

• By creating new soil through the process of deposition

• By reducing the speed of wind erosion

• By freezing and expanding, causing cracks in rocks

What are the different types of erosion caused by water?

• thermal erosion, coastal erosion, landslide erosion, and biological erosion

• splash erosion, sheet erosion, rill erosion, and gully erosion

• wind erosion, glacier erosion, volcanic erosion, and chemical erosion

• abrasion erosion, freeze-thaw erosion, soil erosion, and erosion by gravity

How does wind contribute to erosion?

• By freezing the particles in place

• By compacting the soil and preventing erosion

• By carrying and transporting loose particles such as sand and soil

• By adding nutrients to the soil and promoting plant growth

What are the different landforms created by wind erosion?

• Sand dunes, yardangs, and ventifacts

• Canyons, cliffs, and caves

• Lakes, rivers, and oceans

• Mountains, valleys, and plateaus

How does glacial erosion occur?

• Glacial erosion happens when the ground absorbs too much water

• Glacial erosion is caused by the wind blowing rocks and soil away

• The movement of a glacier scrapes and plucks rocks and soil from the ground, shaping the landscape over time.

• Glacial erosion occurs due to volcanic activity

What are the landforms created by glacial erosion?

• U-shaped valleys, fjords, cirques, aretes, and horns

• Canyons, arches, and hoodoos

• Sand dunes, plateaus, and mesas

• Volcanoes, geysers, and hot springs
