| A | B |
|---|
| ATMOSPHERE | Mixture of gases that surrounds Earth |
| NITROGEN | Makes-up 78% of the atmospheric gases |
| TROPOSPHERE | the layer in which weather occurs |
| GRAVITY | the force that holds the Earth's atmosphere around Earth |
| OXYGEN | 21% of atmospheric gases |
| STRATOSPHERE | home of the ozone layer Ozone layers protects us from the sun's harmful UV ray gases do not mix in this layer |
| CARBON DIOXIDE AND WATER | greenhouse gases found in the atmosphere |
| MESOSPHERE | Coldest layer Meteors burn up in this layer |
| AIR PRESSURE | -Measure of the force with which air molecules push on a Earth, caused by Earth's gravitational pull |
| GREENHOUSE EFFECT | the warming of the surface and lower atmosphere of Earth that occur when water vapor, carbon dioxide, and other gases absorb and reradiate thermal energy (heat) |
| NITROGEN | released when dead plants and dead animals break down and when volcanoes erupt |
| THERMOSPHERE | This layer has very high temperatures, but doesn't feel hot -Divided into two layer (exosphere and ionosphere) |
| GLOBAL WARMING | Gradual increase in average global temperature, due to an increase in greenhouse gases in the Earth's atmosphere |
| OXYGEN | -is made by phytoplankton and plants- released when plants go through Photosynthesis |
| TROPOSPHERE | contains 90% of the atmosphere's mass -densest atmospheric layer -lowest layer of the Earth's atmosphere |
| THERMOSPHERE | -Lowest air pressure-air very thin -Energy from the sun strikes this layer first |
| GLOBAL WARMING | -Burning of fossil fuels and deforestation may cause an increase in greenhouse gases in the atmosphere |
| IONOSPHERE | Lower level of the thermosphere, upper layer of the mesosphere |
| BIOSPHERE | the region on, above, and below the Earth's surface where life exists |
| EXOSPHERE | Outermost layer of the Earth-Outer layer of the thermosphere -Communication satellites orbit in this layer |
| METEOROLOGY | The study of the Earth's atmosphere |
| WEATHER | The condition of the Earth's atmosphere at a particular time and place (temperature, precipitation air pressure, wind speed, cloud coverage etc. ) |
| CLIMATE | The average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area (tropical, polar, dry etc. ) |
| THERMOSPHERE | atmospheric layer with very thin and very hot air |
| IONOSPHERE | -contains electrically charged particles called ions -radio waves bounce off the ions back to Earth in this layer -Aurora borealis (Northern lights) occur in this layer |
| ATMOSPHERE | gases surrounding the planet making conditions suitable for life |
| OZONE (O3) | a colorless, odorless reactive gas comprised of three oxygen atoms. It is found naturally in the earth’s stratosphere, where it absorbs the ultraviolet component of incoming solar radiation that could be harmful to life on earth. |
| TROPOSPHERE | layer that contains weather (water cycle happens here) |
| TEMPERATURE CHANGE | the property used to distinguish between the layers of the atmosphere |
| TROPOPAUSE | the boundary, or transitional layer, between the troposphere and the stratosphere. |
| EXOPSHERE | The outermost atmospheric layer which contains space travel. It's the fifth and last layer of the earths atmosphere, exit from earth into space |
| TROPO | affix meaning "turning or changing" |
| MESO | affix meaning "middle" |
| SPHERE | affix meaning "around" |
| THERM | affix meaning "heat" |
| EXO | affix meaning "outer" |
| ION | affix meaning "charged atoms/particles" |
