Weathering, Erosion and Deposition

How does erosion differ from weathering?

• Erosion moves the rock particles that are broken down by weathering

• Erosion breaks down the rocks and weathering moves it

• Erosion provide nutrients for plants and weathering does not

• Erosion occurs in humid climates and weathering occurs in cold climates

What two main factors determine the rate of weathering?

• climate and age of rock

• type of rock and climate

• chemical and mechanical

• ice wedging and abrasion

The movement of rock particles by wind, water, ice or gravity is called _______________?

• weathering

• erosion

• abrasion

• climate

Why does air chemically weather rock?

• The air molecules are abrasive

• The oxygen in the air combines with elements in the rock in a process called oxidation

• Air fills cracks in the rock and later expands, causing the cracks to enlarge

• The rock wears away after wind blows sand against the rock

A river deposits sediment where it flows into the ocean. Which of these is formed from this process?

• a volcano

• a delta

• a hurricane

• an igneous rock

How does clearing land for construction add to erosion?

• It creates areas of drought

• It adds soils to the area

• It removes plant cover from the soil

• It adds plant cover to the soil
