• Earth's surface is constantly changing

• Change to Earth's surface always takes a long time

Which describes what Earth undergoes all the time?

• plateau

• weathering

• crystallization

Which can cause physical weathering?

• Water

• the crust

• landforms

Which statement below best describes landforms?

• landforms always take shape quickly

• landforms are many different shapes and sizes

• Landforms always take shape slowly

Which is an example of erosion?

• When Earth's plates move

• When rainwater moves soil down a mountain

• When landforms cause physical weathering

How does deposition change the surface of Earth?

• By building up areas of Earth's surface

• By causing earthquakes

• By destroying parts of Earth's surface

How is a landslide like an avalanche?

• Both are caused by erosion

• Both are rapid kinds of erosion

• Both are caused by snow and ice

What causes a volcano to erupt?

• earthquakes heat up magma, which explodes

• Magma comes through the crust in a weak spot

• Movement in Earth's plates heats up magma so it explodes

How can people control erosion?

• Grow plants

• build barriers

• Both growing plants and building barriers

How are earthquakes and volcanoes alike?

• Both happen where plates move and rapidly change the earth
