Troposphere

Stratosphere

The troposphere is the lowest portion of Earth's atmosphere.

The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere and below the mesosphere

Troposphere near the Earth's surface is cooler layers higher up and warmer layers farther down.

Stratosphere  is stratified in temperature, with warmer layers higher up and cooler layers farther down.

About 80 % of the total mass of the atmosphere is contained in troposphere.

This contains about 19.9 % of the total mass found in the atmosphere.

It is also the layer where the majority of our weather phenomenon occurs.

Very little weather phenomenon occurs in the stratosphere
