Why atmosphere is important for life on earth

Without ozone for protection, only the simplest life forms would be able to live on Earth. Greenhouse gases trap heat in the atmosphere so they help to moderate global temperatures. Important greenhouse gases include carbon dioxide, methane, water vapor, and ozone. Skip to main content. The Atmosphere. Search for:. Licenses and Attributions. But methyl chloroform was eventually replaced by other solvents, and over time, its concentrations in the atmosphere have decreased enough that it is no longer useful for estimating OH.

Bowman discussed some of the many other science advances TES has made possible. Its biggest contributions have been in advancing our understanding of ozone in the troposphere. TES data, together with data from other instruments aboard Aura, have significantly improved our understanding of how ozone affects human health, climate and other parts of the Earth system. A TES study showed how ozone produced in Asia was transported around the world, increasing ozone emissions on the U.

West Coast, even as U. TES data also helped quantify how ozone in the upper troposphere serves as a greenhouse gas, warming the atmosphere. TES measurements have also improved our understanding of global air quality by documenting increases in tropospheric ozone levels in many regions of the world, such as Asia.

This, in turn, helps scientists understand what controls the amount of water vapor in the atmosphere. A study using these data showed how the Amazon initiates its own rainy season. In addition, TES provided new information about ammonia, a precursor to harmful aerosols; and new measurements of carbon-containing gases such as methane and carbonyl sulfide, giving scientists new insights into the carbon cycle.

The gases in the atmosphere also protect us from harmful solar rays, but not completely, which is why we often wear sunscreen. The gases trap heat, which the earth naturally produces. Without an atmosphere, the surface of the earth would be very, very cold. The atmosphere also burns up meteors entering from outer space. The moon does not have an atmosphere, and so it is constantly hit with large meteors.

These are just some of the reasons that the atmosphere is important. Can you tell me why the atmosphere is important? Answer 1: The atmosphere is important for many reasons! Answer 2: The atmosphere is important for many reasons. Answer 3: The atmosphere is the air that we breathe, and contains all our weather.

Not much is known about the thermosphere except that temperatures increase with altitude. The uppermost layer, that blends with what is considered to be outer space, is the exosphere. Also called a shooting star or falling star.
