Plate Tectonics!
15
Mid ocean ridge: A long undersea chain that has a steep, narrow valley at its center new organic lithosphere as tectonic plates move apart
Rifting: The process that earths crust breaks apart, can occur within continental crust or organic crust
Continental Drift :The theory, first advanced by Alfred Wegener, that Earth's continents were originally one land mass. Pieces of the land mass split off and migrated to form the continents
Pangaea : The supercontinent that formed 300 million years ago and that began to break up 200 million years ago
Divergent boundary : The boundary between two tectonic plates that are moving away from each other
Sea floor spreading : The process by which new organic lithosphere forms as magma rises to Earths surface and solidifies
Convergent boundary : The boundary between tectonic plates that are colliding
Plate tectonics : The theory that explains large pieces of the lithosphere called plates move and change shape
Continental drift : The hypothesis that a single large landmass broke up into smaller landmasses to form the continent's which then drifted to their present location
Mantle : Section of the Earth below the crust
Fossil : Paleontologists noticed that these were the same on different continent's even though the continent's were separated by oceans
Radioactivity : Source of heat in the mantle
Trenches : Deepest part of the oceans
Theory : A general statement derived from a hypothesis that has withstood sufficient testing
Alfred Wegener : a German geophysicist and meteorologist, was not satisfied by this explanation. proposes "continental drift"
