Weathering and Erosion

The video tutorial explores the concepts of weathering and erosion, highlighting their differences. Weathering involves the breakdown of rocks, soils, and minerals through atmospheric contact without movement, while erosion involves the displacement of these particles by wind, water, and ice. The tutorial delves into types of weathering, such as chemical and mechanical, and explains how natural forces like wind, water, and ice contribute to erosion over geological time, using examples like the Grand Canyon and glaciers.

What is the main difference between weathering and erosion?

• Both involve movement of particles.

• Weathering involves movement, while erosion does not.

• Neither involves movement of particles.

• Erosion involves movement, while weathering does not.

Which type of weathering involves a chemical change in rocks?

• Mechanical weathering

• Physical weathering

• Chemical weathering

• Biological weathering

What causes erosion to occur after weathering?

• The rock particles change chemically.

• The rock particles are moved by natural forces.

• The rock particles dissolve in water.

• The rock particles remain in place.

How do glaciers contribute to erosion?

• By creating tornadoes

• By carrying large boulders to new locations

• By melting rapidly and causing floods

• By moving quickly across the land

What natural event is responsible for forming the Grand Canyon?

• Hurricanes

• Glaciers

• Tornadoes

• The Colorado River
