Theory Of Plate Tectonics

• Theory of how ocean crust was form

• Explains the movement of the water currents

• Explains how major landforms are created as a result of Earth's subterranean

• Describes heat wave currents

Continental Crust

• Layer of the earth that is found in the ocean

• Found below the mantle

• Sand or dirt

• Layer of the earth that supports dry land

Convergent Boundary

• A tectonic boundary where two plates are moving toward each other

• A tectonic boundary where two plates move apart

• A tectonic boundary where two plates slide by each other

• Lines of the continent that separate different countries

Divergent Boundary

• A tectonic boundary where two plates are moving toward each other

• A tectonic boundary where two plates move apart

• A tectonic boundary where two plates slide by each other

• The center of the Earth where all plates meet

Mid Ocean Ridge

• Plate Boundary that forms from plates moving towards each othter

• Part of the ocean where the crust goes deeper down to the earth

• Where the ocean and continents meet

• A continuous range of underwater volcanoes that wraps around the globe

Ocean Basin

• The part of the beach that meets the sand

• Any part of the earth covered by sea water

• Any part of the earth covered by water

• The calmest part of the ocean

Oceanic Crust

• Thin layer of the earth that lays below the oceanic basin

• Layer of the earth that connects land with sea

• Layer of the earth below the inner core

• Where the tectonic plates sit

Plate Boundary

• Boundary that moves ONLY towards each other

• Boundary between Africa and America

• Boundary between two tectonic plates, where the plates are moving horizontally or vertically in opposite directions, not against or away from each other

• Boundary that moves ONLY AWAY from eachother

Subduction

• When two tectonic plates meet and one breaks apart causing the other one to shift

• when two tectonic plates meet at convergent boundaries, and one of the plates moves under the other one due to gravity and differences in density

• When one tectonic plate pulls apart from the other one and rotates directions

• The place where you get sandwiches

Transform Boundary

• Formation of new crust

• Subduction of one plate under another

• Horizontal sliding of plates past each other

• Vertical movement of plates creating mountains
