IN THE AIR
large areas of air with similar temperatures
Air Masses
clouds with ceilings that are at least 20,000 feet
High Clouds
the distance between the Earth and the bottom of a cloud
Ceiling
pattern in which water travels throughout the environment
Water Cycle
type of front that take place when cold air mass runs into a warmer air mass
Cold Front
tiny particles of dust, dirt, smoke, etc. that allow water vapor to hold onto before it can condense to form a cloud
Condensation Nuclei
clouds with ceilings between 6,500 and 20,000 feet
Middle Clouds
the temperature point at which a gas is able to condense
Dew point
a gas that is able to absorb and reflect some of the heat that is given off from the Earth
Greenhouse Gas
type of front where a warm air mass is moving into a cold air mass.
Warm Front
the area where a cooler air mass and a warmer air mass join
Front
clouds with ceilings under 6,500 feet
Low Clouds
when the heat from the sun causes the top of a batch of fog to evaporate
Burn Off
the ability of greenhouse gases like water vapor to absorb and reflect heat from Earth
Greenhouse Effect
type of front in which the cooler air mass from a cold front runs into the cooler air mass inside a warm front
Occluded Front
amount of water vapor in the air
Humidity
clouds that are very high, thin and see- through
Cirrus Clouds
a cloud that forms near the ground
Fog
condensed water on objects on the surface of the Earth whose temperature has reached the dewpoint temperature
Dew
a front that is not moving
Stationary Front
falling droplets of liquid water or frozen ice
Precipitation
clouds that have flat bottoms and large, puffy shapes (almost like cotton balls)
Cumulus Clouds
the change of state of a gas directly into a solid - when water vapor deposits directly onto a surface
Deposition
low pressure area at the center of all storms
Cyclone
clouds that are long, flat and seem to fill up the sky like a large sheet
Stratus Clouds
a visible collection of tiny water droplets or frozen ice pieces floating in the air
