What action resembles that of an earthquake?
Plucking a guitar
200
Which land feature forms where two continental plates move toward each other?
MOUNTAINS
200
What is a land feature such as a sea arch or a canyon called?
LANDFORM
200
A canyon is a result of what type of erosion?
WATER
200
What are some examples of wind erosion?
SAND DUNES
300
What occurs when pressure becomes too great, and rock on one side of the fault suddenly snaps free and slides past the rock on the other side causing the shaking of the ground?
EARTHQUAKE
300
There is a relationship between landforms and wind. Given this relationship, which land form is the result of deposition?
A DESERT
300
The point on Earth’s surface directly above the focus is called?
EPICENTER
300
The water in a fast-moving river causes rocks to bump and scrape against one another. What will happen to these rocks over time?
THEY WILL GET SMALLER
300
Below the Atlantic Ocean floor, two plates move apart. What landform is beginning to develop?
CANYON
400
What are the three types of volcanoes?
SHIELD, CINDER CONE, COMPOSITE
400
A scientist is studying a volcano that is made of alternating layers of liquid lava and explosive materials such as ash. What type of volcano is it?
COMPOSITE CONE
400
what can happen when a plant begins to grow in a rock's cracks?
The roots grow and make the crack wider and bigger, causing the rock to break
400
What are the four layers of Earth in order from the outside to the inside?
CRUST, MANTLE, OUTER CORE, INNER CORE
400
What does the theory of plate tectonics state?
EARTH’S CRUST IS DIVIDED INTO PARTS THAT MOVE
500
Explain how freezing and thawing can cause weathering?
Rocks contain tiny cracks that fill with water when it rains. When the temperature drops, the water turns to ice and expands causing the crack to get bigger. As this happens repeatedly, the rock eventually breaks.

Explain why an earthquake under an ocean is considered less destructive than an earthquake on exposed land.
The earthquakes under the ocean do not affect building structures. More damage occurs when the epicenter is on land.
