Chapter 11 - Atmosphere
Terms in this set (42)
The blanket of gases surrounding earth that contains about 78% nitrogen, 21% oxygen, and 1% other gases such as carbon dioxide, water vapor, and argon.
Absorbs ultraviolet radiation emitted from the Sun. It is made up of three oxygen atoms (O3) that exist in the stratosphere, the second layer in the atmosphere.
The layer of the atmosphere that is closest to Earth's surface. This is where most of the mass of the atmosphere is found, where most weather takes place, and where the majority of air pollution collects.
The layer of the Earth's atmosphere that is made up primarily of concentrated ozone and is located directly above the tropopause.
The small region of transition between the Troposphere, atmospheric layer closest to Earth, and the Stratosphere; the second closest layer of the atmosphere.
The small region of transition between the Stratosphere, the second closest atmospheric layer, and the Mesosphere; the third closest layer of the atmosphere.
The transfer of energy by the flow of a heated substance (occurs with liquids and/or gases).
The energy transfer that occurs when molecules collide with each other; takes place only when substances are in contact with each other.
The energy transfer through space by visible light, ultraviolet radiation, and other forms of electromagnetic waves (occurs with gases only).
The energy transfer that occurs because of a difference in temperature between substances. This energy flow moves from the object with a higher temperature to a object with a lower temperature.
The measurement of how quickly or how slowly molecules move around. This is typically measure in degrees Celsius or Kelvin.
When temperature increases with height in atmospheric level which is the opposite of normal conditions: this can worsen pollution problems.
The temperature at which condensation can occur because the air is cooled at a constant pressure and has reached saturation.
The process by which a cooling gas changes into a liquid and releases thermal energy.
The amount of water vapor in air.
The ratio of water vapor contained in a specific volume of air compared with how much water vapor the air can actually hold.
The point at which air is holding as much water vapor as it possibly can. AKA 100% relative humidity.
Lifted Condensation Level (LCL)
Altitude where air is cooled to the dew point temperature causing condensation and clouds to form. It is level with the bottom of the clouds.
Small particles in the air, either dust or water droplets, around which cloud droplets can form.
The process by which air is lifted over mountains until it cools and reaches saturation. At this point, condensation can occur.
When two fronts collide and the warm air is forced over the colder air because it is less dense. This forced rising of air can produce rain.
The stored amount of energy in water vapor that is released to warm the atmosphere until condensation takes place.
Clouds that are thin, wispy, and feathery
Puffy/ Cotton Ball Clouds
Clouds that appear flat and cover the entire sky/horizon.
The process when cloud droplets collide to form a larger droplet that will eventually become to heavy to be held up and will fall to the ground.
All solid and liquid forms of water, snow, rain, hail, sleet, that fall from clouds.
The change of a substance from a liquid to a gas.
The continual movement of water between Earth's surface and the atmosphere through evaporation, condensation, and precipitation.
Low level clouds below 2000 meters
Mid Level Clouds. Found 2,000-6,000 meters
Very high clouds. Bases start above 6,000 meters
An air mass that does not rise.
An air mass that rises.
One method by which heat flows between air masses of different temperatures.
The layer of Earth's atmosphere directly above the Stratopause and Stratosphere.
The layer of Earth's atmosphere that is located above the Mesopause and only contains a very small portion of the mass of the atmosphere.
The small region of transition between the Mesosphere, the third atmospheric layer, and the Thermosphere the furthest out layer of the atmosphere.
The boundary line between the atmosphere and space.
Another name for the exosphere: Boundary between our atmosphere and space
A combination of evaporation and water loss from plants entering the atmosphere.
