Weathering, Erosion, Deposition

What is the difference between weathering and erosion?

• Weathering breaks down rocks; erosion moves the broken pieces.

• Weathering is the movement of rocks; erosion is the breaking down of rocks.

• Weathering occurs only in cold climates; erosion occurs in warm climates.

• Weathering is a chemical process; erosion is a physical process.

How does erosion affect landforms?

• Erosion shapes landforms by removing soil and rock.

• Erosion has no effect on landforms.

• Erosion only affects water bodies.

• Erosion creates new landforms by adding soil.

How do rivers contribute to erosion?

• Rivers carry away soil and rock as they flow.

• Rivers deposit sediment in lakes and oceans.

• Rivers create new landforms by building up soil.

• Rivers have no effect on erosion.

Can plants cause weathering? How?

• Yes, plant roots can break rocks apart, causing weathering.

• No, plants do not affect rocks at all.

• Plants only help in soil formation, not weathering.

• Plants can only cause weathering through their leaves.

What causes weathering?

• Water, wind, ice, and plant roots.

• Only water and ice.

• Wind and temperature changes.

• Chemical reactions in the atmosphere.

What is deposition?

• The process of eroding rocks and soil.

• The dropping of sediment by wind, water, ice, or gravity.

• The movement of sediment from one location to another.

• The formation of new land through volcanic activity.

What is a landform created by deposition?

• Deltas

• Mountains

• Plateaus

• Canyons

What is erosion?

• The process of moving pieces of rock and soil by water, ice, wind, or gravity.

• The process of breaking down rocks into smaller pieces by chemical reactions.

• The process of planting trees to prevent soil loss.

• The process of creating new landforms through volcanic activity.

What is an example of deposition?

• Sand being dropped to form a beach.

• Water evaporating to form clouds.

• Ice melting into water.

• Soil being eroded by wind.

What role does gravity play in erosion?

• Gravity has no effect on erosion.

• Gravity pulls sediment uphill, contributing to erosion.

• Gravity pulls sediment downhill, contributing to erosion.

• Gravity only affects water flow, not erosion.
