Weathering and Erosion

What is erosion?

• Erosion is the movement of rocks and soil.

• Erosion is the process of planting trees.

• Erosion is the formation of new soil layers.

• Erosion is the chemical breakdown of minerals.

Which of the following does NOT cause erosion?

• Water flow

• Wind

• Plants

• Glaciers

What natural forces can cause erosion?

• Water, wind, glaciers, and gravity

• Earthquakes and volcanic eruptions

• Solar radiation and magnetic fields

• Tides and ocean currents

What is an example of weathering?

• Water freezing in cracks of rocks and causing them to break.

• Wind erosion removing topsoil from a field.

• Plants growing in cracks of rocks and breaking them apart.

• Rainfall causing rivers to flow and shape the landscape.

What is the impact of heavy rain on erosion?

• Heavy rain can increase erosion by washing away soil and rocks.

• Heavy rain has no effect on erosion.

• Heavy rain decreases erosion by compacting the soil.

• Heavy rain only affects erosion in coastal areas.

What is the difference between weathering and erosion?

• Weathering is the movement of rocks, while erosion is the breaking down of those rocks.

• Weathering is the breaking down of rocks, while erosion is the movement of those rocks.

• Weathering and erosion are the same processes.

• Weathering is the process of planting trees, while erosion is the process of cutting them down.

How do glaciers contribute to erosion?

• Glaciers can move large rocks as they melt, causing erosion.

• Glaciers only affect the landscape by creating lakes.

• Glaciers do not contribute to erosion at all.

• Glaciers primarily cause erosion through wind action.

What is an example of erosion caused by rivers?

• Rivers carry rocks from place to place.

• Rivers create lakes by flooding.

• Rivers deposit sand on beaches.

• Rivers evaporate water into the atmosphere.

Can animals cause erosion?

• Yes, animals can disturb the soil and contribute to erosion.

• No, animals have no impact on soil.

• Only certain animals can cause erosion.

• Animals help prevent erosion by stabilizing the soil.

What happens when glaciers move rocks as they melt?

• This is an example of erosion.

• This is an example of sedimentation.

• This is an example of weathering.

• This is an example of deposition.
