seasons on earth are caused by the ____ of ____degrees of the planet tilt of 23.5 degrees
what accounts for our changing weather The atmosphere's continual struggle for temperature balance (air temperature) AIR PRESSURE??
what causes air pressure? caused by the weight of the air pressing down on the Earth, the ocean and on the air below
list some types of precipitation rain, snow, sleet, hail air containing water vapor cools in atmosphere and therefore condenses to form droplets of liquid water
what causes winds to spiral on the surface of the Earth? falling of high to low pressures (Coriolis effect) CAUSED BY PRESSURES VS. SPEED?
what is the rain shadow effect? Prevailing winds pick up moisture from an ocean. On the windward side of a mountain range, air rises, cools, and releases moisture. On the leeward side of the mountain range, air descends, warms, and releases little moisture. THIS MAKES
