TROPOSPHERE |
STRATOSPHERE |
Location |
The troposphere is the lowest layer of the atmosphere, directly above Earth’s surface. |
The stratosphere is the second layer above it. |
Altitude Range |
The troposphere extends up to 12-18 km above the Earth. |
The stratosphere extends from about 18 km to 50 km. |
Temperature Variation |
In the troposphere, temperature decreases as altitude increases. |
In the stratosphere, temperature increases with altitude because the ozone layer absorbs UV radiation. |
Composition |
The troposphere contains most of the Earth’s atmospheric gases, including nitrogen, oxygen, and water vapor. |
The stratosphere has less air but contains ozone, which protects against harmful ultraviolet rays. |
Weather and Clouds |
The troposphere is where all weather events occur, including clouds, rain, and storms. |
The stratosphere has very few clouds and no significant weather activity. |
Air Density and Pressure |
The troposphere has the highest air pressure and density |
The stratosphere has lower air pressure and is less dense. |
