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. |
