Erosion and Weathering Processes

The video explains how changes on Earth can be quick or slow, focusing on weathering and erosion. It describes how wind and water reshape the Earth over millions of years, using examples like the Grand Canyon and Niagara Falls. The processes of weathering and erosion are detailed, showing how they create various landforms.

What is a common way we measure time when discussing changes on Earth?

• Millions of years

• Months and years

• Days and weeks

• Seconds and minutes

What is the process called when wind or water breaks apart rocks?

• Erosion

• Weathering

• Sedimentation

• Deposition

How do geologists determine if a landform was created by wind or water?

• By the size of the rocks

• By the color of the rocks

• By the shape of the landform

• By the location of the landform

What natural feature was formed by water weathering and erosion over millions of years?

• The Amazon Rainforest

What happens to rocks when wind carries grains of sand against them?

• They become smoother

• They become larger

• They become heavier

• They change color

How did Niagara Falls become so tall over time?

• By volcanic activity
