Unit 1: LC 3 Summative

Runoff

Part of the water cycle where an excess of water runs down and does not sink into the soil and eventually makes it to the rivers, lakes, and oceans.

Warm front

a front where warm air moves over cold air and brings drizzly rain and then are followed by warm and clear weather

Air mass

a large body of air whose properties of temperature and pressures are similar

Continental air masses

air masses that form over land; dry air

temperature and humidity

an air mass takes on attributes through...

Polar air masses

cold air masses that originate in polar regions

Maritime air masses

form over water and so have a lot of moisture in the air

Cold front

forms when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow) and or tornadoes

source region

temperature and moisture of air are determined by the ___________ over which they form

Evaporation

the process by which water molecules in liquid water escape into the air as water vapor; role- evaporates water from plants, oceans , lakes, and streams which helps with the creation of clouds

Condensation

the process where molecules of water vapor become liquid water; condenses water vapor into clouds

Tropical air masses

warm air masses that form in tropical or subtropical regions

Stationary front

where warm and cold air masses collide and don't move possibly causing rain(precipitation) for several days because neither air mass is strong enough to overtake the other one

Occluded front

(in a low pressure system) a front where a cold front overtakes a part of the warm front ahead of it and allows for a lot of precipitation to occur because cold air and warm air are now pushing up moisture into to the atmosphere causing more rain because the low pressure system is now getting rid of all the moisture

Precipitation

Any form of water that falls from clouds and reaches Earth's surface. role; brings water back into the bodies of water
