This floats on the asthenosphere and includes all of the crust and part of the upper mantle. It is the cool, solid portion of Earth.
Lithosphere
100
The 3 main layers of Earth.
Core, mantle, crust.

This is approximately 52,000 miles long.
Mid-ocean ridge
100
Name of 3 types of "waves"...
P wave, S wave, Surface wave.
100
This is approximately 30,000 miles long.
Ring of Fire
200
The process of magma being slowly pushed up through cracks in the rift and then cools to form a new sea floor.
Sea-Floor Spreading
200
Ways in which Earth's surface can change.
Movement of Earth's place, erosion, deposition by wind, water, and glaciers, being hit by a meteorite.
200
This boundary is when two plates move apart and hot magma oozes into the gaps, forming new crust.
Divergent boundary
200
This is a push-pull wave.
P wave
200
This volcano is known for it's pointy top, switches between quiet eruptions of flowing lava and violent eruptions of thick gas-rich lava. This volcano has the most powerful eruptions of all.
Composite volcano (Mount St. Helens)
300
The point on the Earth's surface directly above the focus.
Epicenter
300
Names of the 3 types of boundaries.
Convergent boundary, divergent boundary, and transform fault boundary.
300
Many volcanoes form around this type of boundary because melted oceanic crust is slowly pushed upward and then erupts to the surface.
Convergent boundary.
300
This wave causes vibrations at right angles (90 degrees) to the waves' direction of travel.
S wave
300
This volcano looks like the protection a warrior would use in battle. It's broad and slightly domed. These are some of the world's largest volcanoes and may erupt many times over a period of more than a million years.
Shield volcanoes.
400
A mountain that may form around the opening as lava or cinders build up.
Volcano
400
Temperature of Earth's core.
10,000 degrees Fahrenheit.
400
This boundary has a lot of earthquakes.
Transform fault boundary
400
Scale used to measure amount of energy released.
Scale uses to measure intensity/destruction.
Answers must go in order to receive points.
Richter Scale. Mercalli Intensity Scale.
400
How can you tell the Pacific plate is moving northwest?
You follow the trail of volcanic islands and seamounts.
500
The theory scientists use to explain plate movements.
Plate tectonics.
500
How many miles from the crust to reach the inner core?
4,000 miles.
500
"Super continent"
Pangea

At what level of the Richter Scale is there total destruction of buildings?
8.0
500
What type of volcano is most commonly found as a result of hot spots?
