At plate boundaries we see most of the world's ___.

When two tectonic plates are spreading apart we call this boundary:

Scientists today have mapped the Earth’s interior by using

Crust is being destroyed at

Which letter on the map best represents the location of a transform boundary?

Two piece of oceanic crust at this boundary type will make volcanic islands

Volcanoes and a trench are being formed by subduction at

The only layer of the Earth that mankind has actually seen with our eyes?

Which letter on the map best represents a divergent boundary?

Giant mountain ranges are being push upward at

Convection (heat rising) is bringing melted mantle to the surface

At the center of most oceans there exists mid-ocean ridges. These landforms are created by:

When oceanic crust meets continental crust, the oceanic crust is forced down below because

Which letter on the map best represents where new crust is being made?

In Image: A convergent boundary creating volcanic islands would be found at this letter.

The surface of the earth is made up of giant pieces of crust that move and are called __.

According to the continental drift theory, a single, huge continent once existed called:

What force on earth is responsible for moving giant pieces of the crust?

Some volcanoes form away from plate boundaries on their own. We call these locations:

A transform fault is created with earthquakes near the surface at

New crust is being created at

Which layer of the Earth is believed to be in a liquid state?

Plates are sliding past each other

Evidence that helped Alfred Wegener figure out that the continents had moved included
