Q. The first layer of the Earth’s atmosphere is
✅ Correct Answer: (A)
troposphere
Explanation:
The Troposphere is the first (lowest) layer of the Earth's atmosphere.
- It extends from the Earth's surface up to about 8 to 15 kilometers (varies with latitude).
- All weather phenomena like clouds, rain, storms, and winds occur in this layer.
- It contains about 75% of the atmosphere’s mass and the highest concentration of water vapor.
Other layers (above the Troposphere):
- Stratosphere – Contains the ozone layer; located above the troposphere.
- Mesosphere – Middle layer; meteors burn up here.
- Thermosphere – Very high temperatures; auroras occur here.
So, the Troposphere is the first and lowest layer of the Earth's atmosphere.
