The theory that the Earth's lithosphere is divided into tectonic plates that mofve around on top of the asthenosphere.
Ridge Push, Convection, Slab Pull
Three possible causes of tectonic plate motion
The process by which an oceanic plate slides down the lithosphere-asthenosphere boundary due to sea floor spread
Hot material from deep within the Earth rises while cooler material near the surface sinks. When the warmer material cools, it becomes denser and begins to sink back down. The motion of convecting mantle material drags tectonic plates sideways.
Because oceanic lithosphere is denser than the asthenosphere, the edge of the oceanic plate sinks and pulls the rest of the tectonic plate with it in a process called ________________.
The name of the boundary where two tectonic plates push into one another.
When two tectonic plates with continental crust collide, they buckle and thicken, pushing the continental crust upward. True or False?
When a tectonic plate with continental crust crashes into a tectonic plate with oceanic crust, the oceanic plate slides under the continental plate. The region where oceanic plates sink down into the asthenosphere is called a ____________.
The boundary between two tectonic plates that move away from one another; an example is a mid-ocean ridge but these can also be found on continents.
The boundary between two tectonic plates that slide past each other horizontally; This movement can cause earthquakes
Global Positioning System (GPS)
A network of satellites that is used to measure the rate of tectonic plate movement.
