PDE Q41
0. Match List I and List-II and select the correct answer using the codes given below the Lists :
|
LIST 1 |
LIST 2 |
| a) Troposphere | 1. Dust particles |
| b) Stratosphere | 2. Ozone layer |
| c) Mesophere | 3. Meteors |
| d) Exosphere | 4. Aurora |
- Option : B
- Explanation :
Each layer of the atmosphere has distinct characteristics and phenomena associated with it. Matching them correctly:
- Troposphere – 1. Dust particles
The troposphere is the lowest layer where most of the weather and atmospheric dust are found. - Stratosphere – 2. Ozone layer
The stratosphere contains the ozone layer which absorbs harmful ultraviolet rays. - Mesosphere – 3. Meteors
Meteors burn up in the mesosphere due to friction with the atmosphere. - Exosphere – 4. Aurora
Auroras actually occur in the thermosphere, which is often merged conceptually with the upper parts of the exosphere, making this pairing acceptable in general classifications. -
Option A: 1 2 4 3
Incorrect. Aurora is not associated with the mesosphere. -
Option B: 1 2 3 4
Correct. Each layer is matched correctly with its major characteristic. -
Option C: 2 1 4 3
Incorrect. Ozone is not in the troposphere, and aurora is misplaced. -
Option D: 2 1 3 4
Incorrect. Ozone and dust particles are switched between troposphere and stratosphere.
- Troposphere – 1. Dust particles
