because they are made up of gases and the gases protect the earths life forms.
the three major layers that the earth is made up of is the core, mantle, and the crust.
It has 4 layers. Earth layers consist of upper mantle, lower mantle, outer core and inner core.
the troposphere
The Troposphere, Stratosphere, Mesosphere and Thermosphere are gases. These are the layers that make up the atmosphere. The Hydrosphere is a liquid (H2O) and the Lithosphere is a solid. (Hope this helps!) :)
This one...the earth. The other planets are made up of critical gases,like methane, with frozen planets like Pluto made up of layers of frozen gases, such as a suspected layer of oxygen underneath layers of nitrogen and methane, and sulfuric gases which tend to snow out on the cold side of the planet.
