An underwater volcano is a -

• constructive force because i can destroy a coral reef

• constructive force because it can forms islands

• destructive force because it can build land formations to the ocean floor

• destructive force because it can form new land from the build-up of lava

How could human interaction decrease the destructive force of hurricanes on coastal areas?

• create levees to control the water flow

• assess the effects of seismological activity on metropolitan areas

• research the impact of organisms in the Mississippi Delta region

• study storm drain management in the South American rain forests

The Blue Ridge Mountains of Virginia are rounder and smoother than the Rocky Mountains of Colorado. What is the best reason for this difference?

• The Blue Ridge Mountains have more plant and animal life that wears them down.

• It is warmer in Virginia, so ice can't form on the mountains to break the rocks apart.

• The Blue Ridge Mountains are much older and have been exposed to more weathering.

• More people drive in the Blue Ridge Mountains. The traffic has worn the mountains down.

Which of the following human actions prevent erosion?

• Planting trees and shrubs on a hill side

• Covering exposed soil with vegetation such as grass

• Construction of offshore levees and walls to minimize the force of the waves hitting the shore line

• Cutting down trees to make a new road

This bar graph shows the average annual erosion of cropland in Montana for every five years between 1982 and 2010. The lighter segment of each bar represents wind erosion while the darker segment represents sheet and rill erosion. Sheet erosion is the erosion of a thin layer of topsoil over an entire area, usually caused by the particle movement and impact of rainfall. Rill erosion occurs when runoff water create small concentrated channels as it runs down a slope. Based on the data shown, what general statement can be made about Montana's cropland erosion history?

• Sheet and rill erosion moved more soil each year than wind

• Erosion rates were generally steady for 1997-2010.

• Erosion rates have steadily increased since 1982.

• Erosion only occurs every five years in Montana.

• An underwater volcano can be a destructive force because it can destroy a coral reef
