What is the most important layer of the Earth's atmosphere?

Similarly, you may ask, why is the troposphere the most important layer of the atmosphere?

The water cycle helps form clouds, which in form can help produce rain, sleet, snow and freezing rain. As you see, the troposphere is an important layer in Earth's Atmosphere, as it is the layer that we live in and the layer that gives us weather.

Furthermore, why are the layers of the atmosphere important? The atmosphere surrounds Earth and protects us by blocking out dangerous rays from the sun. The atmosphere is a mixture of gases that becomes thinner until it gradually reaches space. It is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%). Oxygen is essential to life because it allows us to breathe.

Then, what are the two most important layers in the atmosphere?

The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.

Why is the troposphere important to the earth?

From the tropopause all the way down to Earth's surface, the troposphere is important because it is where weather occurs. The troposphere provides oxygen that we can breathe, keeps Earth at a livable temperature, and allows for weather to occur, making it a very important part of the atmosphere.
