The liquid layer of the Earth
What is the outer core?
100
The layer that the plates move around on
What is the crust (or lithosphere)?
100
Plate movement eventually led to this breaking apart
What is Pangaea?
100
The slowest and largest waves that cause the most destruction
What are surface waves?
100

Name the three main kinds of volcanoes

What are shield, cinder-cone, and composite volcanoes?

200
The thickest layer of the Earth
What is the mantle?
200

This describes how fast tectonic plates move

What is 0.6cm-10cm per year?

200
A break in rock along which the ground has moved on either side
What is a fault?
200
Waves that travel the fastest and cause rock material to move back and forth
What are primary waves?
200

The key difference between lava and magma

What is lava is molten rock on top of Earth's surface and magma is molten rock under Earth's surface?

300

What geologists call the plastic-like section of the upper mantle?

What is the the asthenosphere?

300

This is an area where two plates meet and converge with one plate sinking and one plate being pushed up.

What is a subduction zone?

300

This is a piece of evidence that proved the idea of plate movement

What is the discovery of identical fossil species on both sides of the ocean basin?

What is the discovery that the coastline of North and South America fit together like puzzle pieces?

300
These move through the rock material by causing particles in the rocks to vibrate at right angles to the direction in which the waves are moving
What are secondary waves?
300

The exact point where slippage occurs at a plate boundary that causes an earthquake

What is the hypocenter or focus?

400

How many plates make up the lithosphere?

What is 8 large plates and many smaller ones?

400

The activities that occur along the Ring of Fire

What are earthquakes and volcanic eruptions?

400

Land feature that occurs when two continental plates are pushed together

What are mountains?

400

The point on the Earth's surface directly about the hypocenter (focus).

What is the epicenter?

400

Yellowstone is an example of this type of volcano

What is a supervolcano?

500

The best explanation of why the inner core is solid metal

What is the immense pressure of the weight of Earth?

500

The characteristics of the 4 main layers of the earth (crust, mantle, inner and outer core)

What is a thin solid crust, a plastic-like mantle, a  liquid outer core, and a solid inner core?

500
Mid-ocean ridges cause volcanic activity because of this type of plate boundary movement
What is moving apart (divergent boundary)?
500
Secondary (S) Seismic Waves can pass through this state of matter
What are solids only?
500

Where earthquakes and volcanoes are most often located

What are edges of plate boundaries?
