| Question | Answer |
|---|---|
| Nitrogen | 78% |
| Oxygen | 21% |
| Argon | 0.93% |
| Carbon Dioxide | 0.038% |
| Water Vapor | 0.0-4.0% |
| Trace Gases | 0.01% |
| Nitrogen and Oxygen levels | don’t change |
| Carbon dioxide and water vapor | can change |
| The increase of Carbon dioxide | is due to the burning of fossil fuels. |
| Water vapor changes | because of location and seasons. |
| Oxygen is | O2. |
| Ozone is | O3. |
| The Ozone layer | blocks harmful layers. |
| Dust, salt, and ice are | the solids found in the atmosphere. |
| troposphere | It is the layer closest to the Earth. |
| It has the most mass. | The temperature decreases the higher you go. |
| The tropopause is where the temperature stops decreases. | Where the weather occurs. |
| stratosphere | It is the second layer from Earth’s surface. Temperature increases as you go up. It contains the Ozone layer. |
| Stratopause is where the temperature stops increasing. mesosphere It is the third layer above Earth’s surface. (Middle layer) Temperature decreases as you go up. Meteor showers occur in this layer. | Mesopause where the temperature stops decreasing.. thermosphere The fourth layer above the Earth’s surface. The temperature increase while you go up. It contains the ionosphere. exosphere |
| Temperature | if particles have more kinetic energy when they are moving faster, so the higher the temperature of material, the faster the particles are moving. |
| Fahrenheit when water freezes | 32 degrees when water starts boiling 212 |
| Celsius when water freezes at | 0 c and water boils at 100 c |
| Kelvin is when water freezes at | 273 k and water boils at 373 k. |
| Air pressure is measured in | millibars (mb) |
| The density and pressure of the layers of the atmosphere | decrease as altitude increases |
| If the temperature increases, but density is | constant, the pressure increases |
| A temperature inversion is an increase in temperature with | height |
| Temperature inversion causes | fog |
| Wind | In the lower atmosphere, air generally moves from regions of higher density and pressure to regions of lower density and pressure. |
| Relative humidity is | the amount of water vapor that air can hold at a certain temperature |
| Relative humidity is | always given as a percent |
| Dew point is | the temperature to which air must be cooled to reach saturation |
| Latent heat | the extra thermal energy contained in water vapor compared to liquid water |
| As warm air mass rises it expands and cools. | |
| The cooling of an air mass as it rises can cause water vapor in the air mass to condense. | |
| Condensation nucleus forms a small particle in the atmosphere around which water droplets can form, and when a number comes together a cloud forms. | |
| Orographic lifting occurs when an air mass is forced to rise over a topographic barrier. | |
| Like a mountain and it causes clouds to form. | |
| Clouds are generally classified by the altitudes at which they form and by their shapes. | |
| Low Clouds they are usually occur be 2000m. | |
| Cumulus clouds are puffy. | |
| Stratus clouds are blanket like clouds. Middle clouds are between 2000 and 6000m. | |
| Middle clouds are between 2000 and 6000m. | |
| Autocumulus clouds are made up of ice crystals and water droplets. | |
| Altostratus clouds | |
| High Clouds are found heights over 6000m, and they are made up from ice because the temperature is freezing. | |
| Cirrus clouds and they are wispy. | |
| Vertical development clouds can reach heights of 18,000m. | |
| Cumulonimbus they can bring storms. | |
| The taller they are the worse the storm is. | |
| Precipitation is water that falls from the clouds they are rain, snow, sleet, and hail. | |
| Coalescence occurs when cloud droplets collide and join together to form a larger droplet. | |
| Explain the difference between stable and unstable air. | |
| When an air mass sinks back to its original position and resists rising, it is considered stable. | |
| Stable air has a tendency to resist movement. Unstable air does not resist vertical displacement. | |
| Compare/Contrast low, middle, high, and vertical development clouds. | |
| Explain how precipitation forms. |
