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
