Erosion, Weathering, and Deposition Concepts

The video tutorial discusses three types of slow changes to Earth's surface: weathering, erosion, and deposition. It uses a model to demonstrate how rain causes weathering by breaking down a mountain, how erosion transports dirt and rocks downstream, and how deposition occurs when these particles settle in a pool. The tutorial also includes a home experiment to observe deposition using dirt and water in a container.

What are the three types of slow changes to Earth's surface discussed in the video?

• Tornadoes, droughts, and wildfires

• Flooding, landslides, and hurricanes

• Volcanic eruptions, earthquakes, and tsunamis

• Weathering, erosion, and deposition

What is weathering?

• The process of rain breaking down rocks over time

• The process of wind shaping sand dunes

• The process of water carrying away soil and rocks

• The process of particles settling at the bottom of a pool

What is erosion?

• The process of wind shaping sand dunes

• The process of water carrying away soil and rocks

• The process of particles settling at the bottom of a pool

• The process of rain breaking down rocks over time

What happens to small particles of dirt and rock in a river?

• They dissolve in the water

• They float on the surface

• They are carried downstream and eventually settle

• They evaporate into the air

What is deposition?

• The process of particles settling at the bottom of a pool

• The process of rain breaking down rocks over time

• The process of water carrying away soil and rocks

• The process of wind shaping sand dunes

What materials do you need for the home experiment?

• A clear container, leaves, and water

• A clear container, rocks, and water

• A clear container, sand, and water

• A clear container, dirt, and water

What should you do after filling the container with dirt and water?

• Shake it well to mix the contents

• Leave it open to the air

• Heat it on a stove

• Freeze it in a refrigerator

What will you observe after shaking the container and letting it sit for a while?

• The water will turn clear

• The heavier sediment will settle at the bottom

• The dirt will float on the surface

• The water will evaporate

What is the purpose of the home experiment?

• To observe weathering

• To observe volcanic activity

• To observe deposition

• To observe erosion

What should you do if you want to get more material for the home experiment?

• Use a larger container

• Use more water

• Dig deeper into the ground

• Add more plants
