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

The crust is broken up into these two categories.

What are oceanic and continental crust?

200
This explains how Earth's processes change a rock from one type to another.
What is the rock cycle?
200
This is the difference between extrusive and intrusive rock.
What is extrusive rock is magma that cools on the Earth's surface and intrusive rock cools 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

These layers of Earth supply the energy needed for convection currents to form.

What are the cores (inner and outer)?

300
These are the three major families of rocks.
What are igneous, sedimentary, and metamorphic?
300

Sedimentary rocks are important because they may contain these things.

What are fossils of plants and 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

Convection currents are found in this layer of the Earth.

What is the Mantle?

400

This explains how rocks are classified.

What is how they form or process?


400
Any rock can become this.
What is metamorphic rock?
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 landform 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

These words mean to be pressed together and glued.

What are compaction and cementation?

500
This is the process in which material is laid down.
What is deposition?
500
This is how climate is evidence of continental drift.
What is tropical plant remains (coal deposits) were found in Antarctica?
500

The process 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?
