100
The inner most part of the earth
What is the core?
100
The single large landmass on earth approximately 245 million years ago.
What is Pangaea?
100
The process by which rocks change shape when under stress.
What is deformation?
100
A place within the Earth along a fault at which the first motion of an earthquake occurs.
What is the focus?
100
Melted rock below the Earth's surface.
What is magma?
200
A region of hot, slow-flowing, solid rock between the crust and the core
What is the mantle?
200
This is formed where two tectonic plates collide.
What are convergent boundaries?
200
This occurs when rock layers bend under stress.
What is folding?
200
The area directly above the focus on the Earth's surface.
What is the epicenter?
200
The opening of a volcano.
What is a vent?
300
The outermost, rigid layer of earth, which is made up of two parts, the crust and the upper portion of the mantle.
What is the lithosphere?
300
Where two plates slide past each other horizontally.
What is a transform boundary?
300
The crack that forms when large blocks of rock break and move past each other.
What is a fault?
300
The return of rock to its original shape after elastic deformation.
What is elastic rebound?
300
Magma that has reached the Earth's surface.
What is lava?
400
The movement of matter resulting from differences in density caused by differences in temperature. Responsible for movement in the mantle.
What is convection?
400
Molten rock from inside Earth rises through the cracks in ridges, cools, and forms new oceanic crust.
What is sea-floor spreading?
400
Stress that pushes rocks in parallel, but opposite directions.
What is shear stress?
400
A large wave that occurs as a result of an earthquake occurring at sea.
What is a tsunami?
400
A location where a column of extremely hot mantle rock, called a mantle plume, rises through the asthenospere.
What is a hot spot?
500
A layer of weak or soft mantle that is made up of rock that flows slowly. Tectonic plates float on this.
What is the asthenosphere?
500
A spot where two plates move away from each other.
What is a divergent boundary?
500
Types of stress that pull rock apart or push rock together.
What is tension and compression?
500
Where most earthquakes occur and where two or more tectonic plates meet.
What is a tectonic plate boundary?
500
A large, basin-shaped depression formed after a magma chamber below a volcano empties, and the roof of the magma chamber collapses.
What is a caldera?
