What are the four types of air masses and where does each form? Polar forms over cold areas, tropical forms over warm areas, continental forms over land, and maritime forms over the oceans. What are four types of fronts? Cold front, warm front, occluded front and stationary front. What happens during a cold front? A cold air mass pushes and replaces a warm air mass. What kind of weather can happen at cold fronts? Heavy rain or snow, cloudy skies or thunderstorms. ...

Which layer of the atmosphere does weather occur? Troposphere relative humidity The amount of water vapor in the air compared to the amount of water vapor the air can actually hold. How do you measure relative humidity? Psychrometer air pressure Weight of the air What causes differences in air pressure? Humidity and Temperature What is an air mass? A body of air with temperature, humidity, and pressure. What determines the conditions of an air mass...

Precipitation - ANSWER-the input to our hydrologic cycle lapse rates - ANSWER-Rates at which air cools and warms. Ideal Gas Law - ANSWER-PV=nRT; predicts that air temp drops at high elevations because air pressure is lower cold air: - ANSWER-holds less water vapor than warm air saturation vapor pressure - ANSWER-Maximum amount of water air will hold (warm air hold more water than cold air) saturated vapor pressure = actual vapor pressure at - ANSWER-15 degrees C General Atmosph...
