This is the name of the crust of the Earth that forms under the ocean.
What is Oceanic Crust?
This is the name for the way that energy travels from an earthquake to the earth's surface.
What are seismic waves?
What is a volcano?
This process powers plate tectonics
What is convection?
The prefix Geo means.
What is ground?
This theory states that all continents had once been joined together and then drifted apart.
What is Continental Drift?
This instrument, which use to consist of a heavy weight attached to a frame by a spring or a wire and a pen that connected to the weight, records ground movements caused my seismic waves as they move through the Earth.
What is a seismograph?
A body of magma below a volcano.
These three layers make up Earth's interior.
What are the crust, the mantle and the core.
The name for a series of mountains that have the same general shape and structure.
What is a mountain range?
This is the longest chain of mountains in the world.
What is the mid-ocean ridge?

What are transform boundaries?
Granite, Basalt and Pumice are this type of rock.
This occurs along plate boundaries, where forces of plate motion compress, pull or shear the crust so much that it breaks.
