What are the three Compositional Layers?

Crust, Mantle, Core

100

What are the three types of boundaries?

Convergent, Divergent, Transform
100

This is the name of the theory that we use today.

Plate Tectonics

100

What is the type of heat transfer responsible for seafloor spreading?

Convection

100

What is the name of the guy who came up with the theory of Continental Drift?

Alfred Wegener

200

What are the five physical layers?

Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core

200

This boundary forms mountains. 

Convergent Continental - Continental

200

This is the name of the original theory that plate tectonics is built upon.

Continental Drift 
200

At what boundary does new crust form? 

Divergent

200

What is the name of the guy who discovered seafloor spreading?

Harry Hess

300

Which layer is the only layer made of liquid?

Outer Core

300

The boundary creates volcanoes.

Convergent Oceanic - Continental

300

This evidence proves plate tectonics and is found at divergent boundaries.

Seafloor Spreading

300
At what boundary is old crust destroyed?

Convergent Oceanic - Continental

300

What is another name for Convergent Oceanic - Continental boundaries?

Subduction Zones
400

Why is the inner core a solid?

It is under so much pressure that it stays a solid

400

Mid Ocean ridges and rift valleys are formed at this type of boundary

Divergent

400

The continents fitting together like a puzzle is primarily evidence for what theory

Continental Drift

400

Which physical layer of the Earth is responsible for the changes in the Earth's surface?

Asthenosphere

400

What do we call the volcanoes around the Pacific Plate?

The Ring of Fire

500

List the physical layers in order of most to least solidity.

Inner Core, Mesosphere, Lithosphere, Asthenosphere, Outer Core

500

This boundary is responsible for forming the deepest parts of the ocean.

Convergent Oceanic - Oceanic

500
This evidence proves plate tectonics by tracking the changes of Earth's polarity.

Paleomagnetism

500

How does the recycling of the Earth's crust affect our study of the Earth's history?

By constantly recycling, the Earth destroys evidence of its history, making it harder for us to study it.

What is another way for crust to be formed in the middle of a plate, away from a boundary?

Hot Spots
