What is the significance of atmospheric oxygen




















All weather takes place in the atmosphere, virtually all of it in the lower atmosphere. Weather describes what the atmosphere is like at a specific time and place, and may include temperature, wind, and precipitation. Weather is the change we experience from day to day. Climate is the long-term average of weather in a particular spot.

Although the weather for a particular winter day in Tucson, Arizona, may include snow, the climate of Tucson is generally warm and dry. Ozone is a molecule composed of three oxygen atoms, O3. Ozone in the upper atmosphere absorbs high-energy ultraviolet UV radiation coming from the Sun.

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. Rashby, S.

The carbon in the fossil fuel, like coal , reacts with the oxygen in the atmosphere to form carbon dioxide. The oxygen in the atmosphere is 'free' for anyone to use. The lack of abundant O 2 under water is what makes submarines hard to power can't burn fossil fuels without O 2 , and lack of O 2 in space requires space missions to use other primary energy sources like radioisotope thermal generators or solar power.
