Explain the significance of gases,dust particles and water content in the atmosphere
Answers
Answer:
They act as surfaces where water can condense (group together), forming clouds from which water droplets can grow large and fall to the ground as snow or rain. Without dust, you could not have clouds or fog. Dust can also absorb or reflect incoming solar radiation. When dust in the atmosphere is high, such as it would be after a volcanic explosion, the amount of sunlight reaching the Earth’s surface will decrease. Dust can also contribute to scattering light, giving rise to more orange and red sunrises or sunsets.
Water Vapor
The amount of water is the atmosphere varies between 1 and 4%. Why is such a small amount such a big deal? Water vapor is the source of all clouds and precipitation, and often that is the most common reason people think of for water. But water does other things too. It has the ability, like carbon dioxide, to absorb heat energy given off by the Earth. It can also absorb solar energy. When water changes from one state to another it absorbs or releases heat. This heat is often called latent (hidden) heat. This is the energy source that helps drive a lot of storms.
