the outer most layer of the earth ; includes oceanic and continental
the layer of the earth between the crust and the outer core; a solid that acts like a liquid; creator of convection currents, earthquakes, and volcanos.
liquid layer of molten iron and nickel that surrounds the inner core of earth; responsible for earth's magnetic field
a dense sphere of solid iron and nickel at the center of Earth
the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle
part of the mantle below the lithosphere where molten rock is soft like taffy
the circular movement of substances (liquids and gasses) due to changes in density; causes plates to shift and move
individual sections of the lithosphere of the earth. They fit together in a way similar to a jigsaw puzzle, but are always moving very slowly, floating on the molten rock of the lower mantle.
the super continent where all the continents were once joined
Wegner's hypothesis that a single large landmass broke up into smaller landmasses to form the continents, which then drifted to their present locations; the movement of continents; however, Wegner had no proof
