Plate Tectonics

Which type of crust is more dense?

• Oceanic Crust

• Continental Crust

• Neither, they are the same

• Pizza Crust

What is created at a Convergent Continental Continental Plate Boundary?

• Volcano

• Rift Valley

• Mountains

• Deep Ocean Trench

Which type of crust is older?

• Continental Crust

• Oceanic Crust

• They are the same age

• The crust isn't alive so they don't have an age

What happens in a Convection Current?

• Cold Magma moves left, hot magma moves right

• Hot magma moves left, and cold magma moves right

• Hot magma rises, cold magma lowers

• Hot Magma lowers, cold magma rises

What happens to the oceanic plate in a subduction zone?

• They collide and nothing happens

• They hit each other and don't move

• It gets pushed up to form mountains or volcanos

• It gets pushed down into the mantle

A Divergent oceanic oceanic plate boundary can make what?

• Mid Ocean Ridge

• Valley

• Mountain

• Volcano

What forms at a transform plate boundary?

• Volcanic Island Arc

• Mountains

• Fault Line

• Trench

The egg white is a good representation of what part of the earth?

• Core

• Mantle

• Crust

• Atmosphere

What two factors identify what type of crust we have?

• Density and location

• Buoyancy and Type of material

• Density and Buoyancy

• Type of material and density

Why does the continental crust float more than the oceanic crust?

• The continental crust is thinner than the oceanic crust.
• The continental crust is more dense than the oceanic crust.
• The continental crust is less dense than the oceanic crust.
• The continental crust has more water content than the oceanic crust.
