Transform Boundary The boundary between two plates that slide past one another -- sudden shifts that result in major geological events such as earthquakes and the release of stored energy.

Asthenosphere ‐ A hot, malleable semi liquid zone in the upper mantle, directly underneath the lithosphere, on which the plates of the lithosphere move (or float). Boundary ‐ The border between two tectonic plates.

Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes.

Lithosphere ‐ the solid outer part of Earth that includes the crust and upper mantle. Magma ‐ melted rock beneath Earth's surface. Mantle ‐ the layer of Earth between the core and the crust; the mantle contains the lower part of the lithosphere and all of the asthenosphere.

Divergent Boundary Occurs when two tectonic plates move away from each other.
