Amplify Geology: Chapter 7: Rock Cycle and Weathering Quiz

What are the two powerful forces at work that are evidence by potholes and grit on roads?

• Gravity and friction

• Weathering and erosion

• Tectonic movements and volcanic activity

• Wind and water currents

What processes drive the rock cycle as mentioned in Chapter 6?

• Weathering and erosion

• Sedimentation and compaction

• Melting and solidification

• Heat and pressure

What does weathering do to rocks?

• It heats them up

• It breaks them into smaller pieces

• It melts them into lava

• It transports them to different locations

What are the two basic types of weathering?

• Physical and chemical weathering

• Biological and geological weathering

• Internal and external weathering

• Abrasive and non-abrasive weathering

What causes physical weathering of rocks in deserts during the day and night?

• Rain and snow

• Plants and animals

• Widely swinging temperatures

• Pollution

What is the process called when water seeps into cracks in rocks, freezes, and causes the rocks to split apart?

• Rock splitting

• Ice wedging

• Water erosion

• Thermal expansion

How do plants contribute to the physical weathering of rocks?

• By shading the rocks from the sun

• By roots growing and acting like wedges in the cracks

• By absorbing water from the rocks

• By covering the rocks with leaves

Which animal activity contributes to the physical weathering of rocks?

• Animals walking over the rocks

• Animals burrowing into cliffs and hillsides

• Animals eating plants near the rocks

• Animals resting on the rocks

What is a powerful chemical weathering force mentioned in the text?

• Oxygen

• Acid rain

• Sunlight

• Wind

What happens when rain mixes with carbon dioxide in the air?

• It forms oxygen

• It creates a physical weathering effect

• It results in acid rain

• It dissolves rocks directly
