Praxis II 0014 Earth System and Plate Tectonics

Atmosphere (air) climate and meteorology
Lithosphere (ground and surface) rock formation, soil formation, plate tectonics, and erosion
Hydrosphere (water) water cycle, currents of rivers, and tides of oceans
Biosphere (life) Ecosystems, habitats, and plant and animal realm
Exosphere (length of atmosphere layer) from 300-600 mile to 6000 miles
Thermosphere (length of atmosphere layer) (includes inosphere) 265000-285000 feet to 400+ miles
Mesophere (length of atmosphere layer) 160000 feet to about 285000
Stratosphere (length of atmosphere layer) 23000-60000 to about 160000 feet
Troposphere (length of atmosphere layer) 23000 to 60000 feet
Crust (earth layer) 5-30 miles thick, not fixed, a mosaic of moving plates, outer shell
Mantel (earth layer) 1800 miles thick, plasticity (ability of solid to flow), circulating currents, causing the plates to move
Outer Core (earth layer) 1300 miles thick, viscous liquid, the earth's magnetic field originates here
Inner Core (earth layer) 800 miles to the center of the earth, a solid
Plate Tectonics about 20, vary in size and thickness continually drift and shift, continental plates and oceanic plates
Convergent (plate movement) collision; creates mountains, volcanoes, ridges, recycling of crust
Transform (plate movement) running; creates earthquakes
Divergent (plate movement) Separating; creates new crust, rivers, oceans, lakes
