Plate Tectonics
•Many pieces of crust, called plates, fit together like a jigsaw puzzle. The plates rest on Earth’s:_________
mantle
•Different types of plate motion produce boundaries that shape different land forms. List the three types of boundaries:
•Divergent
•Convergent
•Transform
•It is a break in Earth´s crust where rock can slide past other rock:__________
Fault
•Define volcano in your own words…
•A volcano is an opening in Earth’s crust where magma can reach the surface.
The strongest surface point of an earthquake
Epicenter
•True or False…
Some plates contain mostly continental crust. Others contain mostly oceanic crust. Many are made of a combination of two
True
•Explain what is a convergent boundary.
A convergent boundary is the movement of two continental plates that crash or move together.
•True or False…
The strongest surface point of an earthquake is the focus.
False
The epicenter is the strongest surface point of an earthquake.
•The liquid rock below Earth’s crust is called:
A.Lava
B.Hot melted rock
C.Magma
Magma
Contains most of the Earth's mass
Mantle
•Multiple choice:
These are three of the largest tectonic plates:
A.Nazca Plate, Cocos Plate, Scotia Plate
B. Australian Plate, African Plate, Indian Plate
C. Pacific Plate, African Plate, North American Plate
C. Pacific plate, African Plate, North American plate
•The North American plate and the Eurasian plate are separating… what kind of land form is it becoming?
A.Mountain
B.Rift
C.Fault
D.None of the above
B. Rift
•Scientists use a device called Seismograph to…
Measure seismic waves
•There are different types of volcanoes:
A.Shield, Cinder Cone, Compulsive
B.Explosive, non explosive
C.Composite, Shield, Cinder Cone
C.Composite, Shield, Cinder Cone
The amount of energy that an earth quake releases
Magnitude
North America and Europe are moving away from each other about 19 mm each year. In 15 years, about how much farther apart will they be than they are today?
A.265mm
B.285mm
C.435mm
D.365 mm
B.285mm
•San Andreas Fault in California is an example of which type of boundary
Transform boundary
•Explain the differences between the Richter scale and the Magnitude scale
•The Richter scale uses the size of waves on a seismograph and the magnitude scale uses a mathematical formula to calculate the energy.
•Why do you think vocanoes are important for scientists ?
•They help them discover what is inside the earth
Pieces of the Earth's crust move in a process called the ______________.

a. Continental crust - found in the continents
b. Oceanic crust - found in the oceans
