Weathering, Mass Movement, and Erosion Quiz

Which process involves the reaction of carbonic acid with calcium carbonate?

• Hydrolysis
• Oxidation
• Carbonation
• Freeze-thaw weathering

What is the main effect of freeze-thaw weathering on rocks?

• It causes rocks to dissolve
• It leads to the formation of clay
• It disintegrates rocks into smaller fragments
• It creates rust-colored surfaces

In which type of mass movement do materials rotate along a curved slip plane?

• Rock slide
• Rock fall
• Slumping
• Landslide

What is the main trigger for mass movement on slopes?

• Wind erosion
• Heavy rainfall
• Temperature changes
• Human activity

How does hydraulic power contribute to coastal erosion?

• By transporting sediments
• By compressing air in cracks
• By creating chemical reactions
• By cooling the rock surfaces

What is the result of abrasion during marine erosion?

• Formation of new landforms
• Scratching and scraping of rock surfaces
• Dissolution of minerals
• Creation of sedimentary layers

Which factor increases the rate of coastal erosion?

• Presence of vegetation
• Hard rock formations
• Large fetch and strong winds
• Stable weather conditions

What happens during attrition in coastal processes?

• Rocks dissolve in water
• Pebbles collide and become smoother and smaller
• Waves crash and erode cliffs
• Sand is deposited on beaches

What is the primary characteristic of a rock slide?

• Curved slip plane
• Straight slip plane
• Rotational movement
• Slow movement of soil

Which of the following is a result of oxidation in weathering?

• Formation of calcium bicarbonate
• Rust-colored surfaces on rocks
• Disintegration of rock into clay
• Crystallization of salts
