Atmosphere Flashcards
The measure of he force with which air molecules push on a surface.
Air pressure
Lowest layer of the atmosphere which lies next to earths surface.
Troposphere
Layer about troposphere and temperature increases as altitude decreases.
Stratosphere
Middle layer and temperate decreases as altitude increases.
Mesosphere
Uppermost layer and temp increases as altitude increases.
Thermosphere
Transfer of energy as electromagnetic waves
Radiation
Transfer of energy as heat through through a material
Thermal conduction
Transfer of thermal energy by the circulation or movement of a liquid or gas.
Convection
Process which gases in the atmosphere such as water and vapor and carbon dioxide, absorb thermal energy and radiate it back to earth.
Greenhouse effect
Gradual increase in average global temp
Global warming
Movement of air caused by differences in air pressure
Wind
Apparent curving of oath of winds and ocean currents dir to earths rotation
Coriolis effect
Wind belts that extend from the poles to 60 degrees latitude in both hemispheres.
Polar easterlies
Wind belts between 30 degrees and 60 degrees latitude in both hemispheres.
Westerlies
Both hemispheres where the winds blow 30 degrees latitude to almost equator.
Trade winds
Narrow belt of strong winds that blow in the upper troposphere.
Jet streams
Combination of atmosphere by the intro of pollutants from human and natural resources.
Air pollution
Rain, sleet, or snow that contains a high concentration of acids
Acid precipitation
Mixture of gases that surrounds a planet or moon.
Atmosphere
Density and transfer of heat
The more dense the material, the better the heat transfers
Layers of atmosphere
Troposphere
Stratosphere
Mesosphere
Thermosphere
Compare earths atmosphere to the glass covering a greenhouse
Both will allow solar radiation through and will both stop energy from escaping
Mountain breeze
At night, when cool air moves down the slopes
Sea breeze
Day time, when water is cooler than land because land is warm. The breeze will become warmer as it comes off ocean and onto land
Land breeze
Night time, when cool air stays on land and warm air stays on ocean.
Relationship between air pressure and altitude
Air pressure decreases as altitude decreases
Where is the ozone layer found and what does it do
Found in the stratosphere and it filters Ultra Violet light
