The Rock Cycle
Types of Rocks
Continental Drift Theory
Plate Tectonics
The Earth's Layers
100
This is the most common material on Earth
What are rocks?
100

To form igneous rock, this moves upwards through the layers of the Earth and cools, then crystallizes.

What is liquid magma?

100
This man proposed the Continental Drift Theory in 1912.
Who is Alfred Wegner?
100
This occurs when plates slide past each other.
What are earthquakes?
100

These are three different names for the top layer of the Earth?

What are oceanic crust, continental crust, and lithosphere?

200
This explains how Earth's processes change a rock from one type to another.
What is the rock cycle?
200

Extrusive means on the surface and intrusive means inside rock that is already formed .

What is magma that cools on the Earth's surface and under the Earth's surface?

200

This is what the Continental Drift Theory suggests.

What is Pangea gradually drifted apart to where the continents are today?

200
This occurs when continental plates converge with oceanic plates.
What is a volcanic mountain range or ocean trench may form?
200

The aesthenosphere contains this. (name at least 1)

What is upper mantle, middle mantle, lower mantle,  and convection currents?

300

These are the two major families of rocks that we learned about.

What are igneous and sedimentary?

300

Sedimentary rocks are important because they may contain these things.

What is water for drinking, petroleum, and fossils of plants/animals?

300
These three things provide evidence of continental drift.
What are fossils, climate, and the continents look like they could be part of a puzzle?
300
This happens when oceanic plates converge.
What is volcanoes or ocean trenches can form?
300
The outer core is composed of these elements.
What are nickel and iron?
400
Rock collections are grouped on the basis of these three things.
What are size, shape, and arrangement of mineral grains?
400

Any rock can become this.

Any rock can become sediment. 

400
This is how fossils are evidence of the continental drift
What is plant and animal fossils are found on the coastline of different continents?
400
This occurs when continental plates converge.
What is folded mountains form?
400
This is the state of matter for the outer core.
What is liquid?
500
This word means "turned into rock."
What is "lithified"?
500

This is the process of rain, wind and other weather breaking apart rocks and forming sediment.

What is weathering?

500
This is how climate is evidence of continental drift.
What is tropical plant remains (coal deposits) were found in Antarctica?
500
The occurs when oceanic plates diverge from one another.
What is magma rises and spreads out, causing sea floor spreading?
500
The inner core is a solid mass of this element.
What is iron?
