Technology and Processes

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 seismologist is a scientist who studies ____________

• floods

• storms

• ocean life

• earthquakes

What is a constructive force?

• A force that destroys nature

• A process that builds up the Earth's surface to deposit sediments and create new landforms.

• A process that destroys the Earth's surface to deposit sediments and create new landforms.

• A process that prevents or predicts destructive forces.

What are destructive forces?

• Processes by which rock is broken down, such as erosion and weathering, either through the violent actions of volcanoes and earthquakes or by the steady flow of a river.

• Processes by which rock is deposited through deposition.

• Processes by which mountains are formed.

• Processes that build up the Earth's surface to deposit sediments and create new landforms.

A levee is a

• pile of dirt

• a flow of river

• a wall along the bank of a river

• wall the block the river

The technology of a seismograph is helpful to humans because it

• identifies locations with poor soil
• records historical temperature extremes
• determines the height of tidal waves
• helps detect and measure earthquakes

Natural phenomena, such as erosion and earthquakes, that wear down landmasses on Earth's surface.

• Flood control
• Destructive forces
• Constructive forces
• Design solution

A seismograph tells us what information about an earthquake?

• How deep within the earth the earthquake occurred.

• How far a tsunami will travel

• How much damage the earthquake caused

• How strong the earthquake is

How does a dam prevent flooding?

• It causes flooding.

• By holding back water from a designated area.

• By allowing water to flow freely through an area.

• None of the above.
