The amount of WEIGHT of air pressing down on the Earth. 

elevation above sea level.

mass of air surronding the earth

weather over a long period time in 1 area.

outer most layer

protects the Earth from harmful U.V. rays

above the Troposphere, temp. increases with altitude

temp. increases with alitude

happens in a short period of time. includes rain, snow, sunshine, etc. 

the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land

passage of water vapor from a plant to the atmosphere

Cooling of gas to water 

Water changes from liquid to gas, caused by heat.

Water droplets falling from the sky in rain, snow, sleet, hail

huge body of air that has similar temperature, pressure, and humidity throughout

weather front in which a cold air mass moves into and under a warm front 

 a boundary separating two masses of air of different densities

Cut off, as the warm air mass at an occluded front is cut from the ground by cooler air beneath it Stationary

a boundary between air masses that don't move possibly causing rain for several days

the leading edge of a warm air mass overtaking a cooler, slower air mass

When the air is above average . Brings good weather 

when the air pressure is below average.

The curving of a path by a moving object.

The tansfer of energy by touch 

The tansfer of energy by liquid or gas 

a path that blows into the upper part of the troposphere.

disturbs warm air unevenly 

A breeze blowing toward the sea at night 

a breeze blowing toward the land during the day 

small scale of winds caused by temp.

winds that blow in 1 direction 

winds that blow east to west 

thin, wispy clouds that usually form above 18,000 feet, composed of ice crystals

puffy clouds that sometimes look like pieces of floating cotton, flat on the bottom and grow vertically

look like a huge gray blanket that hangs low in the sky

High 

precipation prouducing 

used to locate precipitation, calculate its motion, and estimate its type

measures air pressure

eavy storm that consists of rain, strong winds, lightning, and thunder

forms over tropical water, has strong winds and causes thunderstorms 

A rotating column of air that has harsh winds, visible as a funnel cloud
