| Question | Answer |
|---|---|
| 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 |
