NEET Chemistry: Atmosphere questions with solutions

Q1. The layer of atmosphere between \( 10 \mathrm{km} \) to \( 50 k m \) above the sea level is called as:

1. troposphere
2. mesosphere
3. stratosphere
4. thermosphere

Answer: stratosphere

The troposphere ends around 10 km above sea level, and the stratosphere extends upward to about 50 km. Since the given range matches that interval, the correct layer is the stratosphere.
