The only layer of the earth to contain life is the crust. The crust consists of two parts: the continental crust and the oceanic crust. The oceanic crust is below the oceans and is 4-7 miles thick. The continental crust is the surface you see. It is mostly water and 29% land.
Its lithosphere
The kayer that protects life on Earth is the Crust. All the layers together are the Crust, Mantle, Outer Core, and Inner Core.

crust. its the outer most layer of the earth
Convection currents occur in the mantle of the earth. They can affect the crust and the life above it, though.
The awnser is atmosphere. It surrounds the earth protecting the life on earth. Thank you for using this Awner.
Ozone layer protects us from the UV rays. These rays are harmful for life on earth.
Earth is not known to contain the only life in the universe. It is only known to contain the only life we know about. There may be anywhere from a hundred to a hundred million planets with life on them. But earth is the only planet we KNOW off to sustain life because WE have plants, an atmosphere, and oxygen and you need all of those things to keep life going.
Domain Bacteria contain the oldest known fossils of cells in bacterial cells.
It is the only place in the known universe that has been verified to contain intelligent life.
the top soil of earth can support life
Ozone is a layer of importance. It is the reason for life on earth.
The layer of air around the earth supports life and its called the atmosphere.
Its lithosphere
Ozone layer protects the earth from UV rays. These are fatal for life on earth.
The earth has a very thin layer of life-sustaining gasses (known as the atmosphere) surrounding it, mars does not.
Ozone layer is beneficial to all life on earth. It protects the flora and fauna from the UV rays.
