Technology for Constructive and Destructive Forces

How are dams and levees alike?

• Both control floods.

• Both control weathering.

• Both are natural barriers.

• Both prevent coastal erosion.

How do storm drains help prevent flooding?

• They act like levees.

• They move storm water to dams.

• They block storm water from streets and houses.

• They allow storm water to flow into nearby waterways.

A state builds a dam across a river. How will the dam MOST LIKELY affect the region?

• It will prevent flooding by blocking high waves.

• It will rebuild an eroded floodplain by trapping sediment.

• It will prevent flooding by controlling the flow of the river.

• It will reduce erosion by providing a place for storm drains to drain into.

What type of process most likely created the mountain chain seen here?

• Volcanic eruptions created the mountains over millions of years.

• Tectonic plates pushed together forcing one plate under the other and then pushing the land upward.

• Earthquakes broke the earth into pieces and parts of it fell into cracks between faults.

• A river flowed through the land and created the valleys between the mountains making them appear taller.
