Earth Science Chapter 5 Test

The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.

• continental drift

• transform boundary

• convection current

• continent-continent divergence

• Ocean-ocean convergent

The solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle.

• hydrosphere

• biosphere

• asthenosphere

• lithosphere

Extremely deep areas in the ocean that are created by a subducting plate.

• Pangea

• trench

• hot spot

• sea floor spreading

Long, narrow depression formed at divergent boundaries

• trench

• mid-ocean ridge

• rift valley

• ocean basin

A weak spot in the crust where magma has come to the surface.

• hot spot

• earthquake

• convection current

• volcano

The boundary between tectonic plates that are sliding past each other horizontally.

• ocean-continent convergent boundary

• transform boundary

• continent-continent convergence

• ocean-ocean divergence

Creates a rift valley along the opening of the crust. Creates fault zones.

• ocean-continent convergent boundary

• continent-continent convergence

• continent-continent divergence

• ocean-ocean divergence

Term for the super continent which contained all the plates together.

• trench

• Pangea

• crust

• volcano

The thin and solid outermost layer of the Earth above the mantle.

• crust

Proposed the continental drift theory in the 1900's.
