Theory of Plate Tectonics

media

66

The lithosphere is broken into Tectonic Plates

  • The lithosphere is made from the crust and the uppermost part of the mantle

  • The lithosphere is rigid, brittle rock

  • These plates float on the asthenosphere

media

67

media

68

How do the plates ACTUALLY MOVE?

  • Convection currents in the asthenosphere drive the movement of lithospheric plates

media

69

media

70

How does a convection cell occur?

  • Hot magma in the asthenosphere begins to rise, similar to the way hot air rises.

  • As it rises to the top of the asthenosphere, it cools and becomes more dense.

  • This cooler, dense magma then sinks again. As it sinks, it gets warmer, until the process begins again

  • This movement of magma is what drives the plates to move.
