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, 

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

This rock type is formed from layers of weathered debris, minerals, and shells that are pressed and cemented together.

sedimentary rocks

200
This is what the Continental Drift Theory suggests.
What is Pangea gradually drifted apart to where the continents are today?
200

Identify two main types of volcanoes based on their shape

composite and shield

200

Which layer is made mostly of liquid iron and nickel?

mantle 

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

Which type of rock is changed by heat and pressure?

metamorphic

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

What are the large pieces of Earth's crust called?

tectonic plates/ crustal plates

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

What was the name of the supercontinent that once joined all continents?

Pangea

400

This occurs when continental plates converge.

What is folded mountains form?

400

Which layer is the hottest and most dense?

inner core

500

Which is not a type of rock?

(a) igneous

(b) fossil

(c) metamorphic


fossil

500

Give one example of a sedimentary rock

limestone/ sandstone

500

Why was Wegener's theory not immediately accepted?

He could not explain the force that moved the continents.

500

What type of boundary forms when plates slide past each other?

Transform plate boundary


500

this layer consists of hot, molten liquid magma

mantle
