Earth Science Worksheet

planet that we live on
plate boundary where new crust is formed
the center of earth
molten rock that has erupted onto earths surface
a layer of 'plastic' semi solid rock in the lower mantle on which earth's tectonic pates move
plate boundary where lithosphere is destroyed
a chain of island formed at the edge of colliding tectonic plates where one plate subducts
when one plate sinks below another plate during a collisions
mountain formed by crust crumpling upwards as plates collide
the rapid movement of the ground usually up and down in a wave motion due to the movements of tectonic plates
layer beneath earth's crust
a depression in the ocean floor
a zone where earths crust and mantle are being pulled apart
the shaking, wave-like movement of the ground in a earthquake
the point on earths surface directly above the focus of an earthquake
the process of new crust is forming at the ocean ridges and spreading outwards
plates are pulled apart at the mid-ocean ridges
a huge wave in the ocean caused by an earthquake occurring on the sea floor
section of earths crust that moves about on the earths surface
patterns of magnetism trapped in the rocks on each side of plate boundaries
