Precipitation
This scientific term describes a thin blanket of gasses that surround the earth
Atmosphere
In this layer of the atmosphere, weather occurs
Troposphere
This forms when water droplets in the clouds join together to make larger drops
Rain
This tool is used to show the direction that the wind is blowing from
Weather vane
Moving air is called this
This forms from condensed water vapor or ice crystals
Clouds
The measurement of the distance above sea levele
Altitude
The condition of the atmosphere at any moment in time
Weather
The weight of the air is also known as
Air pressure
Winds are identified by this factor in which they blow
The direction they blow
This forms when ice crystals in the clouds join together and fall to the earth
Snow
This substance protects the surface of the earth from the sun's harmful rays
Ozone
It is called this when two unlike air masses meet
A front
Air pressure is measured with this tool
Barometer
Local winds are influenced by changes in this size of area
Small area
This forms when raindrops are pushed into tall clouds over and over again and freeze before falling to the earth
As altitude increases, this happens to the air pressure
Air pressure decreases
This occurs when raindrops fall to the earth and freeze there
Freezing rain
Air is a mixture of nitrogen, carbon dioxide, other gasses, and what?
Oxygen
Wind speed is measured with this tool
Anemometer
This occurs when rain freezes on the way to the earth
Sleet
List the five layers of the atmosphere
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
Any type of solid or liquid water that falls from the atmosphere and reaches the ground can also be called this
Precipitation
An air mass is a body of air that has about the same moisture and what?
Temperature
Global Winds
