Erosion

The video tutorial explains erosion, which is the movement of weathered debris and soil by natural forces such as rivers, glaciers, waves, wind, and animals. It also clarifies the difference between erosion and weathering, the latter being the breakdown of rocks through chemical and physical processes.

What is the primary focus of the initial section of the video?

• The process of erosion

• Chemical weathering

• The role of animals in erosion

• Weathered debris and soil

Which of the following is NOT a cause of erosion mentioned in the video?

• Wind

• Volcanoes

• Glaciers

• Rivers

How do animals contribute to the process discussed in the second section?

• By transporting soil and debris

• By breaking down rocks chemically

• By forming glaciers

• By creating waves

What is the main difference between erosion and weathering as explained in the video?

• Weathering breaks down rocks, while erosion transports them

• Weathering is a type of erosion

• Erosion is caused by animals, while weathering is not

• Erosion involves chemical processes, while weathering does not

Which process involves the breaking down of rocks by chemical and physical means?

• Weathering

• Erosion

• Sedimentation

• Deposition
