short-lived and local patterns of temperature and moisture

long-term patterns of temperature and precipitation

layered ocean of air that extends upward about 500 km

lowest 10–12 km, where weather takes place

redistribute heat and moisture from one part of the globe to another

vary from near zero to 4 percent, depending on air temperature and available moisture

minute particles and liquid droplets play important roles in the Earth's energy budget and in producing rain

-heated layer begins at about 80 km

-region of highly ionized

-producing the aurora borealis and aurora australis, or northern and southern lights.

third layer of the atmosphere directly above the

stratosphere and directly below the thermosphere

-serves as a shield for meteorites.

-more dilute than the troposphere, but it has a similar composition

-has almost no water vapor and nearly 1,000 times more ozone (O3)

-absorbs specific wavelengths of ultraviolet solar radiation, known as UV-B
