Basal Drag/Slab Pull: sinking plates pull the plate with them back into the earth's mantle.
Ridge Push: rising mantle material at mid-ocean ridges pushes plates apart, toward subduction zones.

Mountains & Volcanoes:* Compression Forces (convergent)* 2 continental plates = mountain
* 1 continental + 1 oceanic = volcano
Strike-Slip Faults:* Shearing Forces (Transform fault boundaries)* horizontal movement* example: California
Nov 7-09:24
Testing for Plate Tectonics:* Lasers
* Can measure as little as 1 cm/year
