There is a boundary where each layer ends and a new one begins and a name is given to this boundary – a pause. Distinct temperature differences are found within each layer. For example‚ at the stratopause‚ the temperature stops increasing with altitude. The overlying mesosphere does not absorb

Life on this planet Earth is the product of a delicate balancing act provided by nature. Mankind’s very existence is totally dependent on this fragile ecosystem’s ability to maintain itself. A valuable player in the balance of the environment‚ the ozone layer‚ is facing a very serious threat by man. Chloroflourocarbons (CFCs)‚ are chemical agents commonly found in refrigerants‚ aerosol sprays‚ and in the manufacturing of Styrofoam and industrial solvents. With the rate of more than a half-million

when the atmosphere and environment were different to those presently found on earth Archaea are single cell micro-organisms with no nucleus‚ it use anaerobic respiration (able to living in the absence of Oxygen) and live in extreme environment/condition such as high temperature‚ acid-rich‚ saline area etc. those environment are rich in minerals but hazardous to other organisms. Archaea’s population decreased after earth filled with oxygen‚ other than that‚ current archaea is very same as ancient

the first and upper most layer of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This layer is made frequently from granite rocks and is solid. Continental Crust is approximately 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This part of the Crust is made from basalt rocks. The Crust is most of lithosphere and is the coolest layer by far. Mantle is like silly putty consistency. It is the largest layer of Earth sitting under the Crust. It is made
