Question

Which layer is the most important layer in the atmosphere and why?

Answer 1

Hello!

Atmosphere has all of five layers i.e., troposphere, stratosphere, mesosphere, ionosphere and exosphere.

1. Troposphere is upto some 10-16km where we live.
2. Stratosphere is above troposphere where planes fly.most importantly it has ozone layer to protect the earth from harmful UV-rays
3. Mesosphere, where the temperature again decreases with increasing height and reaches upto -100°C, which is the minimum temperature of the atmosphere.
4. Ionosphere is electrically charged or ionized particles are abundantly found in this layer and temperatures increases with increasing height. This layer reflects back the radio waves.
5. Exosphere is the uppermost and merges with space.

SO, we conclude that every layer is important
