- water cycle
- the sun provides the energy to evaporate water into the atmosphere where it forms clouds and eventually falls back to earth
- weather balloons
- take electronic instruments high into the atmosphere and transmit readings to ground station
- thermosphere
- below exosphere (contains ionsphere= a layer of electrically charged paticles)
- radar
- stands for radio detection adn ranging consists of a transmitter that fires off pulses of microwave radiation
- troposphere
- the air we breath contains 99% of all atomsphere's molecules. contains molecules of O2, nitrogen, traces of wate vapor, CO2 and other gases
- weather
- daily conditions of the atmosphere
- atmosphere
- the multi-layered 600 mile shield of gases that surrounds earth
- 5 layers of the atmosphere
- troposphere, stratosphere, mesosphere, thermosphere, exosphere
- greenhouse effect
- natural heating process of earth and its atmosphere
- AWS
- automatic weather stations are highly technical pieces of equipment based on the ground that take readings of temp., humidity, wind speed, and direction, barometric pressure, and transmit to weather stations
- exosphere
- consists mainly of hydrogen atoms (spaced too far apart to collide)
- satellites
- orbit earth and transmit information about winds, clouds, grond temp., and ocean waves
- mesosphere
- contains nitrogen and oxygen molecules still too thinly spread to allow breathing
- stratosphere
- contains concentrated ozone levels and earth's main shield from the sun's ultraviolet rays
- 4 factors that determine weather
- air pressure, wind, temperature, moisture in the air
