This is the layer of the Earth where we have plates that are like cracked puzzle pieces
What is the crust?
100
This what we call a boundary between plates when the plate are moving away from each other.
What is a divergent plate boundary?
100
This occurs when the forces of two plate moving against one another is released after building up over time.
What is an earthquake?
100
This feature of the earth is an area where magma escapes the earth's crust and becomes lava.
What is a volcano?
100
This is the name given to a fault along a divergent plate boundary, when two plate are moving apart.
What is a normal fault?
200
This is what we call the area where two plates come together
What is a plate boundary?
200
This is what we call the boundary when two plates are moving in toward each other.
What is a convergent plate?
200
All earthquakes are followed by smaller shockawaves. These smaller quakes are called this.
What are aftershocks?
200
True or False:
Volcanoes always occur in the same area as earthquakes.
What is False?
200
This is the type of fault where two plates slide against one another. An example would be the San Andreas fault.
What is a strike-slip fault?
300
This is the name scientists have given to the supercontinent that existed millions of years ago before we had our present day continents.
What is Pangea?
300
This is the name given to a plate boundary where two plates slide against each other.
What is a transform plate boundary?
300
This is the location on the surface of the Earth directly above where an earthquake starts.
What is the epicenter?
300
This is what scientists call a volcano that has not erupted in a very long time.
What is a dormant volcano?
300
This is the type of fault found along a convergent plate boundary when two plates are moving together.
What is a reverse (thrust) fault?
400
This is the layer of the Earth that causes the plates to move and collide
What is the mantle?
400
The area along a plate boundary where earthquakes usually occur is called this.
What is a fault?
400
In the U.S., the majority of earthquakes occur in which state?
What is California?
400
This is the pattern of volcanoes where 75% of the earth's active volcanoes can be found.
What is the Ring of Fire?
400
Susan observe a rock cliff that had layers of rock patterns misaligned (some red rock was much lower than other red rock, and some gray rock was lower than other gray rock). Based on Susan's observations, these patterns were likely caused by which type of fault?
What is a normal fault?
500
The movement of plates that caused Pangea to break apart is called this
What is plate tectonics?
500
Plates move very slowly over time. This can lead to earthquakes because of a build up of force called this.
What is friction?
500
Over time, earthquakes can cause changes to earth's surface. One place where this occured is now the location of many fossils and our focus phenomenon.
What are the La Brea Tar Pits?
500
This is the name of the process by which volcanoes create new land, like in the Hawaiian Islands.
What is deposition?
500
The Champlain Fault can be observed from the sea. It appears that one mountain was placed or pushed right on top of another mountain. This land feature was caused by which type of fault?
