The Components Of Earth’s Atmosphere And How Our Climate Is Affected By Volcanic Eruptions Introduction The atmosphere is all that lies between us‚ and the vast and unforgiving conditions of space. It absorbs energy from the sun‚ protects us from radiation‚ supports the cycle of water and other chemicals‚ and interacts with Earth’s magnetic fields to give us a climate capable of supporting life. Without it there would be no water‚ no air‚ no life. So we must protect it. But to protect

Dioxide play a vital part in the workings of our planet and sustaining life on Earth. The portion of our atmosphere below 12km is called the Troposphere‚ and the portion 40 to 50 km above it is called the stratosphere. Between 50 and 80 km is the mesosphere‚ and above 80 km is the ionosphere. Atmospheric density decreases steadily as altitude increases. As altitude increase so does the pressure relative to ground level. Figure [ 1 ]Earth ’s Atmosphere The troposphere is the area of Earth’s

The ozone layer is located in one of the five layers called the stratosphere which is located about 10-50 km above the planet. The other layers are the troposphere‚ mesosphere‚ thermosphere and exosphere. Figure 1 shows location of the Ozone layer.

The atmosphere is composed of five concentric layers; the troposphere‚ stratosphere‚ mesosphere‚ thermosphere‚ and exosphere. The atmosphere performs several valuable ecosystem services‚ first protecting Earth’s surface from most of the suns ultraviolet rays. Second‚ allowing visible light and some infrared radiation to penetrate‚ both of
