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 the top layers of the Earth?
What are oceanic crust, crust, and lithosphere?
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
The outer core is composed of these.
What is upper mantle, middle mantle, lower mantle, convection currents, and asthenosphere?
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 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.
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 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 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 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?
