Weathering, Erosion, and Deposition

How does freezing water cause weathering of rocks?

• Freezing water causes rocks to melt.

• Freezing water expands cracks and breaks rocks.

• Freezing water has no effect on rocks.

• Freezing water makes rocks more solid.

What is erosion?

• Erosion is the process by which water, ice, wind, or gravity moves weathered rock and soil from one place to another.

• Erosion is the process of breaking down rocks into smaller pieces through chemical reactions.

• Erosion is the movement of tectonic plates that causes earthquakes and volcanic eruptions.

• Erosion is the process of plants absorbing nutrients from the soil.

What happens during deposition?

• Sediments are laid down in a new location after being transported by erosion.

• Sediments are eroded away by wind and water.

• Sediments are transformed into rocks through heat and pressure.

• Sediments are lifted from the ground and carried into the atmosphere.

What is chemical weathering?

• A process that involves the physical breakdown of rocks into smaller pieces.

• Chemical alteration of minerals in rocks due to reactions with water or acids.

• The transportation of sediments from one location to another.

• The formation of new minerals from existing ones without chemical change.

What role does gravity play in erosion?

• Gravity helps move soil and rock downhill, contributing to erosion.

• Gravity prevents soil and rock from moving.

• Gravity has no effect on erosion.

• Gravity only affects water flow, not erosion.

What is mechanical weathering?

• The chemical alteration of rocks due to environmental factors.

• The physical breaking down of rocks without changing their chemical composition.

• The process of rocks melting due to extreme heat.

• The transportation of sediments by wind or water.

What is deposition?

• Deposition is the process where eroded materials are dropped off in a new location.

• Deposition is the process of breaking down rocks into smaller pieces.

• Deposition is the process of water vapor turning into liquid water.

• Deposition is the process of plants absorbing sunlight for photosynthesis.

What is weathering?

• Weathering is the process of planting trees to prevent soil erosion.

• Weathering is the natural chemical or physical processes that break down rock on Earth's surface.

• Weathering is the movement of rocks from one place to another due to wind.

• Weathering is the process of creating new rocks from molten lava.

Can you give an example of weathering?

• Rainwater seeps into cracks in rocks and freezes, causing the rocks to break apart.

• Wind erosion that smooths out the surface of rocks.

• The process of rocks being transported by rivers.

• The formation of soil from decomposed organic matter.

Why is understanding weathering, erosion, and deposition important?

• It helps us learn about weather patterns and climate change.

• It aids in predicting natural disasters like earthquakes.

• Understanding these processes helps us learn about landforms, soil formation, and environmental changes.

• It is essential for improving agricultural practices.
