100
a vent or a fissure in the Earth's surface through which magma or and gases are expelled
What is a volcano?
200
the layer of rock between the Earth's crust and core
What is the Mantle?
200
the hypothesis that the continents once formed a single landmass that broke up and drifted apart to their current location
What is the continental drift?
200
the boundary between 2 tectonic plates that are moving away from each other

a body of molten rock that feeds a volcano
What is magma chamber?
300
the solid outer layer of the Earth that consists of the crust and the rigid upper part of the mantle
What is the lithosphere?
300
the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies

400
the central part of the Earth below the mantle
What is the core?
400
stress that occurs when forces act to squeeze an object
What is compression?
400
a wave of energy that travels through the earth away from the earthquake in all directions
What is a seismic wave?
400
a wide flat landform that results from repeated nonexplosive eruptions of lava that spread over a large area
What is a lava plateau?
500
the strong lower part of the mantle between the asthenosphere and the outer core
What is the mesosphere?
500
the theory that explains how large pieces of earth's outermost layer move and change shape
