MAINTAINS BALANCE BETWEEN HEAT ABSORBED AND HEAT THAT ESCAPES

LIQUIDS, SOLIDS, AND GASES

3.

GASES IN AIR

  • Nitrogen- 78%
  • Oxygen- 21%
  • Water Vapor- 0.4%
  • Rest are traces

6.

CONVECTION

TRANSFER OF HEAT BY THE FLOW OF MATERIAL- WARM AIR RISES-SINKS
7.

WATER CYCLE

  • Evaporation- Sun cause water to change from liquid go gas- rises
  • Condensation- water vapor in atmosphere cools, changes back to liquid
  • Clouds form when condensation occurs high in the atmosphere
  • Precipitation- tiny droplets collide to form larger drops.
  • Grow and fall to Earth as precipitation.

GLOBAL WINDS

10.

DOLDRUMS

WINDLESS, RAINY ZONE NEAR EQUATOR- 0°
11.

TRADE WINDS- 30° N + S

STEADY WINDS THAT BLOW IN TROPICAL REGIONS- BLOW EAST TO WEST
12.

PREVAILING WESTERLIES- 30°TO 60°

BLOWN FROM WEST TO EAST- RESPONSIBLE FOR MUCH WEATHER ACROSS NA

POLAR EASTERLIES- AT THE POLES

  • North Pole- winds blow from Northeast to Southwest
  • South Pole- winds blow from Southeast to Northwest
14.

JET STREAM

  • Blow near top of troposhere
  • Forms boundary at cold, dry polar air to North
  • Warmer, moist air to South
  • Moves faster in winter due to difference in between cold and warm air.
  • Narrow belt of strong winds
