Constructive and Destructive Forces

Which process is most likely to create new land in a short period of time?

• glacial movement

• volcanic eruption

• thunderstorm

• earthquake

The landform below is a sea arch. It could be included as evidence to support which of the following statements?

• Earthquakes are constructive forces that build landforms on the coast quickly.

• Waves are constructive forces that deposit sand and sediments on the coast slowly.

• Earthquakes are destructive forces that cause breakage of rock formations near the oceans.

• Waves are destructive forces that over time can wear away at the earth’s coast and change its shape.

What can be used to explain how a canyon is created?

• Make a hill out of dirt, sediment and sand in a pan, and then use a fan to move the dirt and sand to a new location.

• Make a hill out of dirt, sediment and sand in a pan, and then pour water over the dirt and sand moving it to a new location.

• Make a hill out of dirt, sediment and sand in a pan, and then tilt the container, moving the dirt and sand to a new location.

• Make a hill out of dirt, sediment and sand in a pan, and then drop rocks onto the hill, moving the dirt to a new location.

This town is concerned about erosion from future flooding from the Yellow River. What type of technology should they build to protect against future flooding?

• a levee because it blocks the flow of water

• a levee because it helps reduce erosion

• They should use terrace farming to reduce water runoff.
