What Is An Earthquake??

• is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

• is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane.

• is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

• is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
