The outermost solid layer of Earth.

What is the crust?

100

Divided up parts of the lithosphere.

What are tectonic plates?

100

The bending of rock under stress.

What is folding?

100

All of the continents all connected.

What is Pangaea?

100

The first place on land where an earthquake hits.

What is the epicenter?

200

The center of Earth. It is made up mostly of nickel and iron.

What is the core?

200

Plate boundaries that move toward each other.

What are convergent boundaries?

200

Stress that pulls rock apart.

What is tension?

200

The ridge where seafloor spreading occurs.

What are mid-ocean ridges?

200

The first point where the earthquake occurs.

What is the focus?

300

The outermost rigid layer of Earth.

What is the lithosphere?

300

Plate boundaries that slide past each other.

What are transform boundaries?

300

Stress that pushes rock parallel.

What is shear stress?

300

The trench where convection occurs.

What are deep ocean trenches?

300

Ground movement.

What is an earthquake?

400

The layer of Earth between the core and the crust. (Based on chemical composition.)

What is the mantle?

400

Plate boundaries that spread away from each other.

What are divergent boundaries?

400

Stress that pushes rock together.

What is compression?

400

Cracks in Earth.

What are faults?

400

The result of an earthquake in a giant wave.

What is a tsunami?
