Landforms Review

What causes Earth's surface to shake during an earthquake?

• the downhill movement of rocks and soil

• a fault disappearing into Earth's crust

• the release of energy along a fault

• a tsunami crashing into a coastline

Which of these is the best example of how a volcanic eruption can be a constructive process?

• A volcano erupts violently, destroying part of the top of the volcano

• A volcano erupts large amounts of volcanic ash and gases

• Magma rises through a weak spot in Earth's crust under a volcano

• Molten rock escapes from a volcano and hardens to form new land

Which of these is most likely to cause chemical weathering?

• temperature changes

• plant roots

• rainwater

• wind

Which of these is an example of a destructive process?

• the deposition of material in a river delta

• the movement of material in a landslide

• the building up of a sandbar

• the formation of a volcanic island

What is most likely to cause a river to deposit some of the sediment it is carrying?

• The amount of water in the river increases

• The speed of water in the river decreases

• The river flows down a mountain

• The river flows through a canyon

How are plants most likely to affect the rate of soil erosion?

• Their roots slow it down by holding soil in place

• Their roots speed it up by keeping the soil moist

• Their leaves slow it down by changing the direction of wind

• Their waves speed it up by increasing the force of raindrops

What is likely to cause the most erosion along an ocean coastline in a short period of time?

• tides

• storm waves

• longshore current

• formation of a sandbar

Look at this picture of the coastline. Which feature protects the coastline?

• K

• L

• M

Which of these is likely to reduce erosion of farmland?

• leaving some plant materials on the field at all times

• plowing the soil to plant crops

• stripping away the top layer of soil

• removing trees growing at the edges of fields

What process destroys landforms?

• Constructive forces

• Landslides

• Destructive forces
