Weathering, Erosion, Deposition

What is weathering?

• The process of breaking down rock into small pieces.

• The process of forming new rocks from magma.

• The movement of rocks from one place to another.

• The process of changing the chemical composition of rocks.

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 transporting nutrients from the soil to plants.

• The process of forming new land by volcanic activity.

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 the impact of ice on weathering?

• Ice can cause rocks to melt and erode.

• Ice can expand in cracks of rocks, causing them to break apart.

• Ice has no effect on weathering processes.

• Ice can absorb moisture from the air, preventing weathering.

What causes weathering?

• Water, wind, ice, and plant roots.

• Only water and wind.

• High temperatures and humidity.

• Earthquakes and volcanic eruptions.

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 without removing material.

What is an example of deposition?

• Sand being dropped to form a beach.

• Water evaporating from a lake.

• Ice melting into water.

• Soil being eroded by wind.

What is a landform created by deposition?

• Deltas

• Mountains

• Plateaus

• Canyons

What is the difference between weathering and erosion?

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

• Weathering and erosion are the same processes.

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

• Weathering occurs only in dry climates, while erosion occurs in wet climates.

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.
