Troposphere
All of the layers are important to some degree, however in my opinion the troposphere is because that is what we live in.
The lowest atmospheric layer that contains greenhouse gases is the troposphere
The mesosphere is the atmospheric layer that protects the Earth from meteoroids. As meteoroids enter the Earth's atmosphere, they burn up in this layer due to friction with air molecules, preventing them from reaching the surface.
The atmospheric layer below the mesosphere is called the stratosphere. It is located above the troposphere and below the mesosphere, and it contains the ozone layer which absorbs and scatters the sun's ultraviolet radiation.
The atmospheric layer closest to the Earth's crust is the troposphere. It is where we live and where most weather phenomena occur.
Ozone layer is very important for human beings. It protects us from the harmful UV radiations of the sun.
The ozone layer of the earth is a very protective and important layer. This layer is a boon at the atmospheric level.
some harmful radiations reach to earth and can damage skin of human beings and plants
Human beings were not there. Complex life had not being evolved.
All of the layers are important to some degree, however in my opinion the troposphere is because that is what we live in.
The Exosphere is the atmospheric layer the farthest distance from the lithosphere.
The troposphere is the closest to the Earth and most dense atmospheric layer
ozone layer
Earth's atmospheric layer contains ozone layer. It protects us from harmful UV radiations of the sun.
The atmospheric layer containing pollution is troposphere. It the nearest to earth.
The ozone layer is not found on the earth. Rather it is founded in the atmospheric layers.
The ozone layer in the stratospheric region is in danger as it is being depleted. It is because of the high use of ozone depleting substances by human beings.
