Praxis II 0014 Earth System and Plate Tectonics
Question | Answer |
---|---|
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 |
