Rocks on the Surface
If you can see rocks on the surface that comes from the interior, you can study them

5. Rocks can deform and flow

Rocks can deform and flow
Easier for rock to deform and flow when it is warmer

6. 12/12/2019
Lithosphere
Lithosphere is a planet’s outer layer of cool and relatively rigid rock
Asthenosphere is the region in the upper mantle characterized by low-density, semiplastic (or partially molten) rock material chemically similar to the overlying lithosphere

18. Principles of Plate Tectonics

Principles of Plate Tectonics
1. The surface of the Earth is composed of lithospheric plates that are in constant motion.
The plates move in response to plastic flow in the athenosphere.
Motion in the asthenosphere is caused by convection driven by the Earth’s internal heat.
The internal heat comes from radioactive decay and the latent heat from the Earth’s formation.

19. Three Types of Plate Tectonic Boundaries

Three Types of Plate Tectonic Boundaries
Divergent – plates move apart, space is filled with molten magma
Convergent – plates collide
Transform – plates slide horizontally past each other
