• continent

• fossil

• landmass

According to Wegener's theory of continental drift,

• Earth's surface is made up of seven major landmasses

• the continents do not drift

• Earth is slowly cooling and shrinking

• the continents were once joined together in a single landmass and have slowly moved.

What is the process that continually adds new crust to the ocean floor along both sides of the mid-ocean ridge?

• subduction

• continental drift

• convergent

• sea floor spreading

In sea floor spreading, molten material rises from the mantle and erupts

• along the edge of the continents

• along the mid-ocean ridges

• in deep ocean trenches

• at the North and South pole

What is the process by which the ocean floor sinks beneath a deep ocean trench and back into the mantle?

• continental drift

• mid-ocean ridge

• faults

• subduction

Most geologists think that the movement of Earth's plates is caused by

• conduction

• earthquakes

• convection currents in the mantle

• Earth's magnetic field

Why does the oceanic crust sink beneath the continental crust at a subduction boundary?

• The oceanic crust is hotter

• The oceanic crust has a greater density

• The oceanic crust has a lighter density

• The oceanic crust has more magnetic composition
