the thin and solid outermost layer of the Earth above the mantle
the layer of rock between the earth's crust and core
the central part of the Earth below the mantle
the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle
the soft layer of the mantle on which the lithosphere floats
The strong, lower part of the mantle between the asthenosphere and the outer core
a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations
the process by which new oceanic lithosphere forms as magma rises toward the surface and solidifies
the theory that explains how large pieces of the Earth's outermost layer, called tectonic plates, move and change shape
the boundary formed by the collision of two lithospheric plates
the boundary between two tectonic plates that are moving away from each other
the boundary between tectonic plates that are sliding past each other horizontally
stress that occurs when forces act to squeeze an object
Stress that occurs when forces act to stretch an object
the bending of rock layers due to stress
a break in a body of rock along which one block slides relative to another
a fault in which the hanging wall moves down relative to the footwall
A fault in which the hanging wall moves up relative to the foot wall
opposing forces cause rock to break and move horizontally
When rock layers are squeezed together and pushed upward.
Form when tension causes large blocks of rock to drop down in relation to other rocks. Tilting of rock layers can occur as tension pulls the rock layers apart.
Mountains that form when magma erupts onto Earth's surface.
