Plate Tectonics - A scientific theory that explains how major landforms are created as a result of Earth's subterranean movements., Pangaea - refers to the supercontinent that is believed to have included all of the landmasses around the world., Continental Drift - A theory that states that large, moving pieces of Earth’s outer layer called plates have moved across Earth’s surface for hundreds of millions of years. , Tectonic Plates - Pieces of Earth's crust that are divided into large pieces that move on top of the mantle., Mid-Ocean Ridge - occur along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart. , Sea Floor Spreading - happens at the bottom of an ocean as tectonic plates move apart causing the seafloor to move and carry continents with it., Divergent - at these boundaries, tectonic plates move away from each other., Convergent - Boundaries where tectonic plates collide or come together., Transform - Boundaries that occur when two plates slide past each other horizontally., Subduction Zone - the action of two tectonic plates colliding and the less dense plate, submerges underneath the denser one., Earthquake - Occur when two large pieces of the Earth's crust suddenly slip and cause shock waves to shake the surface of the Earth., Tsunami - A large ocean wave usually caused by an underwater earthquake or a volcanic explosion., Fault - A fracture, or break, in the Earth's crust (lithosphere)., Volcano - a spot in Earth's crust where molten rock, volcanic ash and certain types of gases escape from an underground chamber. , Lava - hot, liquefied rock that flows from a volcano or other opening in the surface of Earth., Magma - Molten, or hot liquefied, rock located deep below the Earth's surface , Ring of Fire - A chain of volcanoes that surrounds the Pacific Ocean and frequently erupt in fiery explosions., Alfred Wegener - A German scientist known for his theory of continental drift.,
