What is one way that Earth's surface is built up?
deposition, movement of glaciers, movement of water, actions of magma in Earth's crust, deposits of animal remains
200

Name one major solid landform in the United States.
Answers will vary
300
Deposition is a constructive or destructive force?
Constructive- builds Earth's surface up
300
How is mechanical weathering different from chemical weathering?
mechanical weathering is the breaking down of rocks/sediments into smaller pieces. Chemical weathering is when rocks/sediments change into a new material
300
Slow changes like erosion, cause fast changes like ________.
Landslides or sinkholes

Volcanic activity is an example of constructive or destructive forces?
Constructive- Volcanoes erupt and they build up Earth's surface (lava hardens)

Name one way that erosion wears down Earth's surface.
frozen water, such as glaciers, carve out hollows in land, moving water creates river valleys, ocean waves and currents break down rocks along coastlines, canyons
