Geology is the study of what?

Geology is the study of Earth's physical structure & substance.

150
How many layers are within the earth that we study?
3

Define Volcano.

Volcanos forms when a fracture, or break, in the upper mantle allows magma from below to be pushed through the surface of the Earth.

150

Define Erosion.

Erosion is the movement of soil from one location to another.

What are the 3 main types of rocks?

Igneous, Metamorphic, & Sedimentary

What are the 3 layers of Earth?

Core, Mantle, & Crust

250

Define Earthquake. 

Earthquakes occurs along fault lines due to stresses within the Earth’s crust.

250

Define Weathering.

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth.

250

________________ are the pieces of Earth's uppermost layer called the crust.

Plate tectonics

350

Define Lava.

Lava is magma that comes to the surface of the earth.

350

How many ways can erosion occur?

4

350

Define deposition.

Deposition occurs when sediments stop moving and they get deposited into a new place.

450
Most volcanos, whether on land or water are located where?

Volcanos are mostly located where tectonic plates meet. 

450

How often do the plate tectonics move every year?

1-2 inches (depending on your resources)

450

List the 3 types of volcanos.

Cinder cone, shield, & composite

450

What are the 4 ways that Erosion can occur?

Gravity, Wind, Water & Glacial Ice

How does Igneous Rock form?

Igneous Rock forms when magma cools & hardens.
