Regions of Earth

• Lithosphere: the solid part and the largest portion of the earth
• Crust: 10-20 miles deep; divided into basaltic oceanic crust and granite continental crust
• Mohorovicic Discontinuity (Moho): boundary that separates crust from mantle
• Mantle: thickest layer; divided into asthenosphere, upper mantle, and lower mantle
• Outer Core: it's so hot that the metal is always molten
• Inner Core: densest part of the earth’s interior
• Hydrosphere: the liquid part
• It covers about 71% of the earth’s surface
• Evaporation: sun’s heat converts water to water vapor; water vapor can also come from transpiration that occurs on the surface of plant leaves
• Precipitation: water falls back to the Earth’s surface (as rain, snow, sleet, etc.)
• Dispersion: particles of air nearer the surface of the earth are denser, and they gradually disperse with increasing altitude (due to decreasing gravity as altitude increases)
• Mesosphere: most meteors disintegrate due to its freezing temperature
• Stratosphere: where the ozone layer located
• Exosphere: continuous of outer space
• Biosphere:the region where living things are found.
• Thermosphere: gets hot as one goes hotter
• Troposphere: where weather activities occur
• Atmosphere: the gaseous portion that envelops the earth
• Condensation (Cloud Formation): water vapor/ice releases heat, returning to droplet form
