Atmosphere

The atmosphere is a term used to describe the mixture of different gasses  that surrounds Earth. These gases consist predominantly of nitrogen, oxygen, argon, carbon dioxide, and water vapour. Most people believe the atmosphere is thick. However, it’s a very thin. The two most important service functions of the atmosphere are storage and life protecting.

  1. Storage service for oxygen and carbon dioxide that are essential for the biosphere.
  2. Protection of life from solar radiation

The atmosphere is one of the five reservoirs included in the Earth system; the four others are Geosphere,  Hydrosphere, Biosphere and the Anthroposphere; finally, the atmosphere outermost layer is the boundary of the Earth system and separates us from other objects in space. The atmosphere consist of a set of layers whereof the first and closest to Earth is troposphere (sealevel-11.000 metres) The layer nearest the Earth’s surface, rising from sea level to about 6 miles (11 km), is the troposphere. The primary heat source for the troposphere is infrared energy (heat) that radiates from Earth’s surface.

The next levels is called the stratosphere, rises from 11 km (11.000 metres) to 45 km (45.500 metres ) the layer is heated by the suns UV rays and with increasing proximity to the sun it get warmer. Stratosphere is also host for the ozone layer witch is measured between 15-30 km from Earth’s surface, this layer despite all the space it takes in media coverage it relative small (measurement of 12 ozone molecules for every billion air molecules). This is also one of the reasons that the stratosphere warms with altitude. The last two layers of the atmosphere is the mesosphere and finally thermosphere

The layers of the atmosphere:

  • Troposphere
  • Stratosphere
  • Mesosphere
  • Thermosphere
