100
The thin and the out most layer of the Earth above the mantle.
What is Crust
100
The strong lower part of the mantle between the asthenosphere and the outer core.
What is mesosphere
100
The process by which new oceanic lithosphere forms as magma rises towards the surface and solidifies.
What is Sea floor spreading
100
the boundary formed by the collision of two lithospheric plates.
What is Convergent boundary
100
The boundary between two tectonic plates that are moving away from each other.
What is Divergent boundary
200
The solid, outer layer of the Earth that consists of the crust and the rigid upper layer of the mantle.
What is lithosphere
200
the soft layer of the mantle on which the tectonic plates move.
What is asthenosphere
200
A block of lithosphere that that consists of the crust and the rigid outer most layer of the mantle.
What is Tectonic Plates
200
The theory that explains how large pieces of the Earth's outer most layer called Tectonic plates move and change shape.
What is Plate Tectonics
200
A wide, flat land form that results from repeated nonexplosive eruptions of lava that spread over a large area.
What is Lava plateau
300
A vent in the Earth's surface through which magma and gasses are expelled.
What is Volcano
300
The bending of rock layers due to stress.
What is Folding
300
The central part of the Earth below the mantle.
What is Core
300
The hypothesis that the states where once one.
What is Continental Drift
300
Stress that occurs when forces act to squeeze an object.
What is Compression
400
A break in a body of rock along which one block slides relative to another.
What is Fault
400
The boundary between tectonic plates that are sliding past each other horizontally.
What is Transform boundary
400
Stress that occurs when forces act to stretch an object.
What is Tension
400
The point on Earths surface directly above an earthquakes starting point, or focus.
What is epicenter
400
The study of earthquakes
What is seismology
500
A large semi-circular depression that forms when the magma chamber below a volcano partially empties and causes the ground above to sink.
What is caldera
500
The body of molten rock that feeds a volcano.
What is Magma chamber
500
a wave of energy that travels through the Earth and away from an earthquake in all directions.
What is seismic wave
500
An area of deep cracks that forms between two tectonic plates that are pulling away from each other.
What is rift zone
500
The layer of rock between the Earth's crust and the core.
What is Mantle
