name is the most common solids and liquids suspended in air
Answers
A suspension of liquid droplets or fine solid particles in a gas is called an aerosol. In the atmosphere, the suspended particles are called particulates and consist of fine dust and soot particles, sea salt, biogenic and volcanogenic sulfates, nitrates, and cloud droplets.
Answer:
. Liquid or solid particles suspended in the air
. Some occur naturally, originating from
volcanoes, dust storms, forest and grassland
fires, living vegetation, and sea spray.
. Some are anthropogenic: burning of fossil
fuels, slash and burn, alteration of natural
surface cover due to land use changes.
. Aerosols from human activities ~10% of total,
mostly conc. in N. Hemisphere, downwind of
industrial sites, slash-and-burn, overgrazed
grasslands.
. Aerosol particles > 1 µm produced by
windblown dust and sea salt; < 1 µm mostly
formed by condensation processes (e.g., SO2 to
sulphate particles)
. Aerosols produce more vivid sunsets
. We are not sure whether aerosols are overall
warming or cooling the planet
