What is the average height of troposphere?

Correct option is B

The correct answer is (b) 13 km.

• The troposphere is the lowest layer of Earth's atmosphere, where most of the planet's weather occurs.
• The average height of the troposphere is about 13 kilometers (8 miles) above sea level, though this can vary from about 8 kilometers at the poles to around 18 kilometers at the equator.

Layers of Earth's Atmosphere:

Troposphere:

• Height: Extends up to 8-18 km.
• Characteristics: Weather phenomena occur here; temperature decreases with altitude.

Stratosphere:

• Height: 18 to 50 km.
• Characteristics: Contains the ozone layer; temperature increases with altitude.

Mesosphere:

• Height: 50 to 85 km.
• Characteristics: Meteors burn up here; temperature decreases with altitude.

Thermosphere:

• Height: 85 to 600 km.
• Characteristics: Temperature increases with altitude; contains the ionosphere.

Exosphere:

• Height: 600 km and above.
• Characteristics: Thin outermost layer; merges with space.
