$100 mantle Back

What is the plastic layer of the mantle on which pieces of the lithosphere move?

$200 Asthenosphere Back

What is the only liquid layer of the Earth’s interior?

$300 Outer Core Back

We know much about the interior of the Earth because we have mapped the movement of these.

What is the name of the scientist who first hypothesized the idea of continental drift?

$100 Alfred Wegener Back

The present day continents were once joined in a large continent known as this.

$200 Pangaea Back

What is the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies?

$300 sea-floor spreading Back

The rate at which the continents move per year can be measured in what units of length?

$400 centimeters Back

When magnetic reversals occur on the ocean floor, what element is found in the rock that helps us measure the magnetic direction?

$500 iron Back

$200 transform boundary Back

What is the name for the boundary where two tectonic plates are separating away from each other?

$300 divergent boundary Back

Where will the next ocean form, millions of years from now?

$400 Red Sea Back

Oceanic lithosphere at mid-ocean ridges slides downhill under the force of gravity because of this:
