SSC CGL 2025 PYQ — Question 27

SSC CGL - 16 Sep 2025 - Shift 2 • General Awareness • Q27

Which pair correctly matches atmosphere layer & feature?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Troposphere - weather.

The Troposphere is the lowest layer of Earth's atmosphere, extending roughly up to 12 km. It contains approximately 75% of the atmosphere's mass and 99% of its water vapor and aerosols. Consequently, almost all weather phenomena, such as clouds, rain, and storms, occur in this layer. As altitude increases within the troposphere, the temperature typically decreases. It is the most vital layer for life as it provides the air we breathe.

Other Options:

  • Thermosphere - ozone: Incorrect; the Ozone layer is actually located in the Stratosphere, where it absorbs harmful UV radiation.

  • Mesosphere - satellites: Incorrect; satellites usually orbit in the Exosphere or Thermosphere, while the Mesosphere is where meteors burn up.

  • Stratosphere - meteors: Incorrect; the Stratosphere is known for ozone and jet flying, whereas meteors burn up in the Mesosphere.
