ATMOSPHERE
COMPOSITION AND HEATING
- The atmosphere is a mixture of gases that surrounds a planet or moon
- The atmosphere is made of 78% Nitrogen, 21% oxygen, 1% other gases.
- When atmospheric conditions change water vapor changes from a gas to a solid and it rains, sleets, or snows.
- Air pressure is the measure of force where air molecules push on a surface.
- Air temperature changes as altitude increases.
- LAYERS OF ATMOSPHERE:
- Troposphere
- (& ozone layer) Stratosphere
- Mesosphere
- Thermosphere
- (ionosphere) - home of the Auroras
- The Earth receives energy from the sun by radiation.
- Radiation: the transfer of energy as electromagnetic waves.
When you touch something hot that is thermal conduction. Thermal conduction is the transfer of energy as heat through a material.
- Watching something boil is convection, convection is the movement of matter due to differences in density.
WIND
- The movement of air caused by differences in air pressure, is wind.
- Air rises ay Equator and sinks at the Poles.
ferences in air pressure cause the coriolis effect.
- The Coriolis Effects the appearent curving of the pat do to the Earths rotation, in the northern hemisphere winds traveling north go to the east and in the southern hemisphere.
- The winds that move to the east in the northern hemisphere are Polar Easterlies.
- The winds that move to the west in the southern hemispher are westerlies.

POLLUTION
- Air pollution is contamination of the atmosphere by the introduction of pollutants from human and natural sources.
- Smog is a mixture of ozone and exhaust when reacted with sunlight.
- Primary pollutants are pollutants from natural sources.
- Secondary pollutants are primary pollutants that have reacted with other primary pollutants.
- Cars contribute to almost 20% of pollution
