MAIN SPHERES

ATMOSPHERE

• exosphere - highest, thinnest layer
• thermosphere - hottest layer
• mesosphere - coldest temp, where meteors disintegrate
• stratosphere - temp increases with altitude, ozone layer found here
• troposphere - lowest layer, weather layer

GEOSPHERE

HYDROSPHERE

BIOSPHERE

CONSTRUCTIVE FORCES

• plate tectonics
• uplift - edges squeezed slowly upward, lifting the ocean floor & forming mountains
• volcanoes
• earthquakes
