Marano- Weather 1
| Question | Answer |
|---|---|
| weather | the present condition of the atmosphere at any location |
| solar radiation | weather changes as the result of ______ hititng the various layers of the atmosphere |
| solar energy | the main source of heat energy |
| rises, drops | heat _____ and cold air ____ |
| atmosphere | mixture of gases and tiny solid particles that surround the Earth and protect us from the sun's harmful rays |
| layers of the atmosphere | TSMITE- troposphere, stratosphere, mesosphere, ionosphere, thermosphere, exosphere |
| troposhere | layers closest to Earth, densest layers contains almost 90% of atmosphere's total mass |
| altitude | height of an object above the Earth's atmosphere |
| decreases | In troposphere as altitude increases, temperature _____ |
| ozone | molecule made of three oxygen atoms |
| ultravioloet radiation | ozone absorbs solar energy in the form of _____ |
| mesophere | coldest layer of the atmosphere |
| ionosphere | upper mesophere, nitrogen and oxygen atoms absorb harmful solar energy |
| Aurora Borealis | Northern lights- ions radiate energy as light of different colors |
| thermosphere | temperature increases with altitude and many gases are absorbing solar energy |
| exosphere | outer space |
| air temperature | the amount of heat (solar radiation) that reaches the Earth |
| angle of solar radiation | sun light that is directly overhead (90 degrees) will heat you more than light that is just over the horizon |
| Dark objects absorb the sun's energy (quickly, slowly) and heat up fast. | quickly |
| Light objects such as snow,ice, and water absorb the sun's energy (quickly, slowly) and heat up very slowly. | slowly |
| gcloud cover | only a small portion of the tremendous amount of the sun's energy actually enters the Earth's atmosphere due to ______ |
| reflection | 25-34% of the sun's energy is bounced back to space by clouds |
| absorption | 19-20% of the sun's energy is soaked up by the atmosphere (water vapor, dust, ice crystals) |
| The sun's energy is _____ to the objects closest to the ground warming them up. | refracted |
| At night time _____ act like a blanket and keep heat in our atmosphere | clouds |
| radiation | transfer of energy from the sun, heats Earth's surface |
| conduction | contact- transfer of thermal energy from one object to another by direct contact |
| convection | most thermal energy in the atmosphere moves by ____ |
| convection cell | created when lighter hot air rises, cools and then heavier cool air drops |
| Greenhouse effect | Earth's heating process where the gases in the atmosphere, such as carbon dioxide and water vapor trap thermal energy |
| Global warming | an increase in average global temperatures as greenhouse gases such as, carbon dioxide, increases |
