Plate Tectonics
9
Plate tectonics: theory of the formation and movement of the plates that cover the Earth's surface.
Divergent Boundaries: From when two lithospheric plates move apart.
Continental Drift: Theory that all continents are fragment of Pangaea now drifting apart.
Sliding Boundaries: Forms when two lithospheric plates slide past each other.
Converging Boundaries: forms when two lithospheric plates come together.
Lithospheric Plates: A number of rigid, but moving, pieces of the Earth's surface.
Seafloor Spreading:states that youngest rocks of ocean floor are at diverging boundaries, moving outward.
Asthenosphere: the partially melted layer of the mantle that underlies the lithosphere.
Lithosphere: The outer shell of the Earth that extends to a depth of 100km.
Pangaea: theory that at on point, 200 million years ago, all the continents were joined as a giant landmass.
