atmospheric pressure
the force of air pressing on the Earth's surface
climate
average weather over a long period of time
Thermal conduction
The transfer of energy as heat through a material
convection
the movement of matter due to differences in density; the transfer of energy due to the movement of matter
radiation
the transfer of energy as electromagnetic waves
greenhouse effect
The warming of the surface and lower atmosphere of Earth that occurs when water vapor, carbon dioxide, and other gases absorb and reradiate thermal energy
ionosphere
region of ionized gas in the thermosphere (reflects radio waves)
mesosphere
The layer of the atmosphere between the stratosphere and the thermosphere and in which temperature decreases as altitude increases
ozone layer
blocks ultraviolet radiation from the Sun, Layer of the stratosphere with a high concentration of ozone; absorbs most of the Sun's harmful ultraviolet radiation
thermosphere
the uppermost layer of the atmosphere in which temperature increases as altitude increases
troposphere
the layer of the atmosphere closest to the Earth's surface where most weather occurs, temperature decreases at a constant rate as altitude increases, contains 90% of Earth's mass
weather
the state of the atmosphere in a particular place at a particular time
Global warming
a gradual increase in average global temperature
wind
movement of air by the uneven heating of the earth and changes in pressure
coriolis effect
the apparent curving of the path of a moving object form an otherwise straight path due to the Earths rotation
Jet stream
narrow belt of strong winds that blows near the top of the troposphere
air pollution
the contamination of the atmosphere by the introduction of pollutants from human and natural sources.
acid precipitation
rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water
acidification
the process of becoming acid or being converted into an acid
sea breeze
movement of air from sea to land during the day when cooler air from above the water moves over the land, forcing the heated, less dense air above the land to rise
polar Easterlies
Prevailing winds that blow from east to west between degrees-degrees latitude in both hemispheres.
Westerlies
prevailing winds that blow from west to east between 30 degrees & degrees latitude in both hemispheres.
wind
The movement of air caused by differences in air pressure
atmoshphere
a mixture of gases that surrounds the planet
air pressure
The measure of the force with which air molecules push on a surface
stratosphere
The layer of the atmosphere that is above the troposphere and in which temperature increases as altitude increases
trade winds
Prevailing winds that blow northeast from 30 degrees north latitude to the equator and that blow southeast from 30 degrees south latitude to the equator
