PPT-TEKS 8.9 (B) Relate plate tectonics to the formation of crustal features.

  There are three main types of tectonic plate boundaries convergent divergent and transform Types of stress that changes crustal features Stress Directions Compression Rocks are being squeezed. The word tectonics derives from the Greek tektonikos, meaning "pertaining to construction." Earth habitable. ? . Earth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another.. as a random outcome of . time-dependent convection. Teresa Wong. Slava. . Solomatov. Theory of Earth II. AGU .
