This mabye? The atmosphere is the thick layer of gaseous material which surrounds the Earth.  Most of the atmosphere lies within 97 km of the Earth’s surface, but it has no definite boundary. The atmosphere is divided into four layers, theTroposphere (0-10 km altitude), the Stratosphere (10-45 km altitude), the Mesosphere (45-80 km altitude), and the Thermosphere (80-300 km altitude).  The atmosphere comprises: 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide and very small amounts of other gases.  These gases are often termed ‘greenhouse gases’ as they are delicately balanced to maintain the Earth’s temperature at a level suitable to sustain life. Without these gases, and the natural greenhouse effect, the average temperature of the Earth would be approximately -18°C (0°F) instead of its current 14°C (57°F) (see NOAA). Earth is one of the few planets in the solar system which has an atmosphere. Venus, one of our closest neighbours has an atmosphere made of 96.5% carbon dioxide (CO2) and 3.5% nitrogen (N2), which forms a very toxic atmosphere, allowing it to maintain a sweltering surface temperature of 467°C!

 

The lithosphere is the term given to the rock and minerals which form Earth’s outer crust and its tectonic plates. This is an important part of the Earth’s system as these rocks become eroded and weathered to provide important minerals to the other Earth systems.  Through Earth’s history, the entire lithosphere has been recycled approximately six times.  At the outermost layer of the lithosphere, the ‘pedosphere’ (meaning soil sphere) exists at the interface between lithospheric, atmospheric, biospheric and hydrospheric processes. The combination of these processes leads to soil formation, which is essential for sustaining life on Earth (the biosphere).

 

The biosphere refers to all types of life on Earth, including plants, animals, and bacteria.  Over the history of the Earth the biosphere has changed considerably with a great number of species evolving, adapting, and becoming extinct.  The diversity of the biosphere varies greatly across the Earth, as species can be highly vulnerable to even minor variations in climate. A slight change in air temperature or moisture, for example, can alter the type of vegetation (flora) which is able to grow in a given location. This may in turn affect the distribution of animals (fauna) as they move or adapt in tune with vegetation availability.


I did not do this i got it from somewhere but i can't get post the link so dont thank me!
