Lithosphere Covers Earth in a thin shell, not a solid sheet of material
Techtonic Plates Pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere.
Plates Edges called boundaries, move into each other and pull apart
Locked Plates get --- as they move, then 'jerk' into a new position
Vibrations Plate slipping and sudden movement cause
Quakes and Volcanoes One process of changing the Earth's surface
Earthquakes This happens at faults; cracks in the crust usually along plate boundaries
Volcanoes These form near colliding plate boundaries on land or ocean floor
