weather vocab

The activity in the atmosphere above us each day. weather
The average weather trends over a long period of time climate
the scientific study of the atmosphere and weather meteorology
the sphere of air-the envelope of gases that surround the planet atmosphere
anything that has mass and takes up space matter
these are made up of protons, neutrons and electrons atoms
when two or more atoms, whether the same or different combine molecules
there are approximately 109 of these of which everything we know is made. elements
solid, liquid and gas 3 states of matter
the homogenous mixture of gases that consists of 78% nitrogen and 21% oxygen that goes from the ground to 50 miles up homosphere
the gas layer above the homosphere that contains helium and hydrogen hetrosphere
the lowest layer in the atmosphere from ground to 9 miles where all weather takes place troposphere
this is the layer of air that begins above the troposphere and goes up about 25 miles and includes the ozone layer stratosphere
these are winds that travel in patterns in the stratosphere gong almost 300 mph and pilots fly in it to increase speed and save fuel jet stream
this contains 3 atoms of oxygen bonded together and shields the earth from harmful untraviolet light ozone layer
this layer is above the stratosphere and goes above the earth about 50 miles and is the coldest layer in the atmosphere mesophere
this layer is the uppermost layer where the molecules are exposed to radiation of the sun and it is very hot thermosphere
air expands (increases in volume) when heated and contracts (decreases in volume) when cooled Charles' Law
the force whid which the weight of the air presses down on the Earth Atmosphere Pressure
This is created by masses of warm air bobbing up over the ground like huge lightweight balloons making the weight of the air on the Earth low. low pressure zones
this results from Heavier, colder air hunkering down on the Earth's surface like oozy sacks of mud making the seight of the air on Earth high High pressure zones
This happens when warm rising air mixes with cool lowering air wind
the device used to measure atmospheric pressure barometer
