Continental Drift & Plate Tectonics Review

The asthensosphere is the

A plate is a rigid block of the Earth's crust.

This layer is a liquid layer of the Earth

The newest/youngest rocks on Earth are found

A divergent boundary are plates that move apart.

This layer of the Earth varies in thickness.

The pool of magma inside a volcano is called

As you go toward the center of the Earth what increases?

The meteorologist that came up with the theory of Continental Drift was:

A seismograph measures

Facts that support Continental Drift are:

The Ring of Fire is

Pangaea means

When plates colide they can form:

Relative age of fossils

The openning at the top of a volcano is called

I am soooooo going to ACE this test!!!!

A convergent boundary is when plates slide by each other.

How do plates move?

Absolute age

Plates move at a rate of

This is the hottest layer of the Earth

Continental Drift is when continents plow through the seafloor to their present day position.

Magma is in the mantle and lava is on land

Pangaea split about

This is the thickest layer

A magnetometer measures

A Transform Fault boundary is when plates move together.
