Document Summary

Clouds: clouds r composed of suspended water droplets and ice crystals. A micrometer is a millionth of a meter: vapor condenses or freezes around the solid particle. This solid particle, which aerosol condenses or freezes this nucleus which the vapor condenses is the (cid:272)o(cid:374)de(cid:374)satio(cid:374) (cid:374)u(cid:272)leus.

For example wind blowing across bare soil can lift soil up into the atmosphere. When wind blows acros water surface, ocean, vast lake, water droplets can be lifted into the air. The water evaporates and the tiny specs of salt are suspended. Or when waves crash against the shore, the spray of se water thrusts into the air. Or meteoric dust (cid:449)he(cid:374) e(cid:454)t(cid:396)ate(cid:396)(cid:396)est(cid:396)ial o(cid:271)je(cid:272)ts (cid:271)u(cid:396)(cid:374) i(cid:374)to ea(cid:396)th"s atmosphere, some of the dust produced. Anthropogenic sources are processes by which aerosols are produced by air pollution like combustion of fossil fuels.
