PPT-Plate Tectonics, Part 2

Layers of the Earth 1 2 24 3 24 Plate Tectonics Earths lithosphere is broken up into plates Hot weak asthenosphere allows for plates to move Plates are in motion and continually changing in shape and size. Simplified Plate Tectonics MapPlate boundary - Known area between two plates.Some plate boundaries, such as the North America - South America boundary, are not shown because scientic dataare inadequa 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 .
