What is stress?
Stress is the amount of force per unit area that is placed on an object.

Any place where gas, ash, or melted rock come out of the ground
What is a volcano?

When an earthquake hits at home, what do you do?
Duck, cover, hold
200
The layer of Earth that extends form below the mantle to the center 
What is Earth's core?
200
The large scale movements of Earth's lithosphere, which is made up of the crust and the rigid, upper part of the mantle
What is plate tectonics?
200
What is deformation?
Deformation is the process by which rocks change shape when under stress. 
200
An opening of a volcano
What is a vent?
200
What is an earthquake?
The ground movements that occur when blocks of rock in Earth move suddenly and release energy
300
The layer of Earth that's located between the core and the crust
What is Earth's mantle?
300
Sea-Floor Spreading
What is the process where molten rock rises through cracks, then cools, and forms new crust (the old crust break at the ridge and pieces move in the opposite direction)?
300
What is folding?
Folding occurs when rock layers bend under stress
300
What is viscosity?
The resistance of liquid material to flow is called viscosity 
300
The return of rock to its original shape after elastic deformation.
What is elastic rebound?
400

 a) Lithosphere                                                           b) Asthenosphere                                                     c) Mesosphere

a) Lithosphere     

400
What is convection?
Convection is the movement of matter that results from differences in density caused by temperature.
400
Which of the following is NOT a type of mountain?

 a) folded                                                                   b) fault- block                                                           c) cinder                                                                   d) volcanic

 c) cinder 

400
A large, basin shaped depression
What is a caldera? 
400
Normal faults form at what kind of plate boundaries?

Normal faults form at divergent plate boundaries.

500
Why is the outer core important?
Because it creates the Earth's magnetic field
500
When two plates collide, it is called a ________ boundary.

 a) Divergent                                                             b) Convergent                                                           c) Transform

b) Convergent    

500
Strike-slip faults are caused by what kind of stress?

Strike-slip faults are caused by shear stress

500
What is the ring of fire?
The ring of fire is the explosive volcanoes that form on convergent plate boundaries surrounding the Pacific Ocean
