| Question | Answer |
|---|---|
| Layer closest to Earth | Troposphere |
| Layer in which all weather occurs | Troposphere |
| Layer directly above troposphere | Stratosphere |
| Thin concentration of ozone in lower stratosphere | Ozone Layer |
| Importance of Ozone Layer | Absorption of UV light |
| Layer above the stratosphere | Mesosphere |
| Layer above the mesosphere | thermosphere |
| Layer in which auroras occur | Ionosphere within the thermosphere |
| Layer which reflects radio waves | Ionosphere within the thermosphere |
| Layer in which jets fly (cruise) | Stratosphere to stay above the weather |
| Ozone is destroyed by | CFC's chlorofluorocarbons |
| The troposphere begins at what level? | ground level |
| the transition between the troposphere and the stratosphere is called the | tropopause |
| anvil-shaped tops of cumulonimbus clouds occur at the tropopause because | there is no convection in the stratosphere |
| There is no convection in the stratosphere because | temperature inversion (it does the opposite of the troposhpere) |
| transition between mesosphere and thermosphere is called the | mesopause |
| transition between stratosphere and mesosphere is called the | stratopause |
| name the layers of the atmosphere from ground level up | troposphere,stratosphere, mesosphere,thermosphere,exosphere |
| the formula for ozone is | O3 |
| a single oxygen is called | ozium |
| "free oxygen," what we normally call oxygen has the formula, | O2 |
| temperatures actually increase with altitude in which two layers? | stratosphere and thermosphere |
| atoms and molecules can escape from this layer into space | exosphere |
| this layer is called the upper atmosphere | thermosphere |
| satellites can orbit within this layer | exosphere |
| this layer is made of electrically-charged particles | ionosphere |
| the ionosphere exists because of | radiation from the sun striking the atmosphere and IONIZING the atoms/gases there into ions |
| atoms that have gained or lost electrons are called__ | ions |
| how atoms become ions | electrons lost or gained |
| exact location of the ionosphere | occupies all of the thermosphere and the upper part of the mesosphere |
| layer that can conduct electricity | ionosphere |
| ionized gases glowing as a result of a huge amount of incoming radiation at the (magnetic) north pole | aurora borealis |
| ionized gases glowing as a result of a huge amount of incoming solar radiation at the (magnetic) south pole | aurora australis |
| meteors typically burn out in this layer | mesosphere |
| incoming fragment into our atmosphere that has not landed and is called a shooting star | meteor |
| incoming fragment that impacts earth | meteroite |
| the actual interplanetary debris that is the fragment entering the atmosphere is called this. | meteor |
| auroras are composed of this | ionized gas |
| This unit of measurement that measures the amount of gas in a vertical column of air is primarily used to measure the amount of atmospheric ozone. | Dobson Unit |
