What are the most important layers of the atmosphere to humans?

i think it's the troposphere

the ground, and the layer of breathable air above it

All of the layers are important to some degree, however in my opinion the troposphere is because that is what we live in.

Different layers have different function in the atmosphere. For example the stratosphere protects from UV rays.

No, nitrogen is the most important gas in the atmosphere.

The innermost layer of the Sun's atmosphere is the photosphere. The other layers of the atmosphere are the chromosphere and the corona. The layers of the interior, from the inside to the outside, are the core, the radiative zone, and the convection zone.

trosposphere is the most important layer in the atmosphere

Ozone is beneficial in any layer of the atomosphere, except the troposphere where humans and food sources would be directly attacked by it. Some ozone is found in all layers of the atmosphere, but most is concentrated at the bottom of the stratosphere. This ozone concentrated region is called the ozone layer.

Humans live their lives in the troposphere.

The most important elements in the Earth's atmosphere are N (nitrogen) and O (oxygen).

The most important gases when studying the atmosphere are nitrogen and oxygen (as O2 and O3).

There are four major spheres of the Earth, which are lithosphere, biosphere, atmosphere and hydrosphere. The atmosphere is divided into five layers, which are (in order from closest to surface to furthest from surface) troposphere, stratosphere, mesosphere, thermosphere and exosphere.

The stratospheric region of atmosphere contains most of the ozone. It is present as ozone layer.

The layer of atmosphere in which most of the ozone is concentrated is stratosphere. It is in the form of ozone layer in the stratosphere.

Important gases in the atmosphere mainly are nitrogen, oxygen and carbon dioxide.

The atmosphere. The atmosphere has many different layers that filter most of the harmful light of the sun. the ozone layer!!!!!

The troposphere is the most dense since it is closest to the surface of the earth and has the highest pressure.

The most important gas in this case is carbon dioxide.

The atmosphere. a jelly fish and humans

This gas is ozone (O3).

They are not, bacteria is the most important species - without them humans would not last more than a few hours.

Earth's atmosphere is comprised of four different layers including the troposphere, stratosphere, mesosphere and the thermosphere. The troposphere has about 80% of the total mass of the atmosphere.

crust, outercore, mantle, innercore

Atmosphere molecules filter out the most of colours of the spectrum when it passes through thicker layers of the atmosphere. When the sunlight goes through a shallower angle, it must penetrate through more layers than it usually does during the day.
