What is mantle?
The outermost layer of the earth on which we live, and on which the oceans, land and seas exist.
What is the crust?
Scientists use this tool to measure the magnitude of an earthquake.
What is a seismograph?
Dams are created to control the force of water, they are
What are "C" (constructive)?
The process of moving sediment by wind, moving water, and ice.
What is erosion?
The word that describes the surface feature created by river erosion over a long period of time.
What is a canyon?
The type of force that can change the way the earth looks, but does not damage landforms or buildings.
What is constructive?
This human created structure is a plug in a stream. It is a barrier built across a stream or river to stop or check the flow of water.
What is a dam?
Tsunamis can move up to 600 miles per hour with waves of up to 30 feet toward a coastline. It is a _____ force.
What is destructive?
The process of dropping or depositing, sediment, in a new location.
What is deposition?
Landform created by deposits of sand blown by wind and gathered over a period of time.
What are sand dunes.
The innermost part of the earth structure made of iron and nickel.
What is the core (inner core)?
A barrier designed to prevent the overflow of water onto land. Examples of these barriers were set up in New Orleans to prevent the flow of water and that failed during Hurricane Katrina, causing great flooding.
What are Levees?
Land slides can create land forms with benefits as well as great cost to property and human lives. These are...

What is convergent?
The act or task of reclaiming a beach from erosion by adding sand to the area that was lost to erosion "reclaiming" the shoreline that once was.
Bonus: The process that takes the sand from the ocean floor and puts it back on the beach.
What is beach reclamation?
Bonus: What is dredging?
Based on the category, deposition is ______
What is a destructive force?
The theory of how continents move over the earth's surface.
What is continental drift?
A landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water (constructive force).
What is a river delta?
A fault could be described as a ______ in the earth's crust.
What is crack or crevice?
Two processes that farmers use to help control soil erosion on their fields.
What are contour plowing, terrace farming, and/or planting rows of trees?
Volcanos are ______
What are both "C" constructive and "D" destructive forces?
