Atmosphere

Vocabulary1 ozone- a colourless gas with a chlorine-like odour, formed by an electric discharge in oxygen: a strong oxidizing agent, used in bleaching, sterilizing water, purifying air, etc.2 troposphere-the lowest layer of the atmosphere, 6 miles (10 km) high in some areas and as much as 12 miles (20 km) high in others, within which there is a steady drop in temperature with increasing altitude and within which nearly all cloud formations occur and weather conditions manifest themselves.3 statosphere-the atmospheric layer lying between the troposphere and the mesosphere, in which temperature generally increases with height4 mesophere-the atmospheric layer lying between the stratosphere and the thermosphere, characterized by a rapid decrease in temperature with height5 thermosphere-the region of the upper atmosphere in which temperature increases continuously with altitude, encompassing essentially all of the atmosphere above the mesosphere.6 exosphere-7 radiation-8 conduction-9 convection-

What is the importance of water vapor in the atmosphere? Water vapor in the atmostphere is the basic formation of clouds, so without water we wouldn't have rain, hail, snow. Water Vapor is also the Most Important Greenhouse Gas. As a greenhouse gas, the higher concentration of water vapor is then able to absorb more thermal IR energy radiated from the Earth, thus further warming the atmosphere. “Water vapour is the most important greenhouse gas. This is part of the difficulty with the public and the media in understanding that 95% of greenhouse gases are water vapour. The public understand it, in that if you get a fall evening or spring evening and the sky is clear the heat will escape and the temperature will drop and you get frost. If there is a cloud cover, the heat is trapped by water vapour as a greenhouse gas and the temperature stays quite warm. If you go to In Salah in southern Algeria, they recorded at one point a daytime or noon high of 52 degrees Celsius – by midnight that night it was -3.6 degree Celsius. […] That was caused because there is no, or very little, water vapour in the atmosphere and it is a demonstration of water vapour as the most important greenhouse gas.” (Tim Ball)

Why does temperature increas with height through the startosphere?Because the stratosphere contains a large about of concentrated ozone, that absorbs ultra violent radiation and thus causes the layer to warm.
