The primary basis for dividing the atmosphere into various layers is the change in temperature with altitude. In the troposphere, temperature decreases as you go higher, while in the stratosphere, it actually increases due to the ozone layer. These distinct ...

The correct sequence from the surface upward is the Troposphere, Stratosphere, Mesosphere and Ionosphere. The troposphere is the lowest layer where weather occurs. Above it lies the stratosphere, followed by the mesosphere, where temperatures drop significantly. Finally, the ionosphere is ...
Nitrogen makes up approximately 78% of the Earth’s atmosphere by volume. This vast majority ensures that the atmosphere is stable and not overly reactive. While nitrogen is essential for life, particularly in the formation of proteins and DNA, it remains ...
The process described is known as the greenhouse effect. It involves the atmosphere trapping heat that has been reflected or re-emitted from the Earth’s surface in the form of infrared radiation. Greenhouse gases like carbon dioxide and methane are the ...
Ozone is the atmospheric gas that protects life from being scorched by the sun’s intense ultraviolet rays. Most of this gas is concentrated in the stratosphere, forming the ozone layer. It acts as a biological shield, absorbing high-energy radiation that ...
