Match List I with List II
Choose the correct answer from the options given below:
| LIST I | LIST II | ||
|---|---|---|---|
| A | Troposphere | I | Approximate 65-75 km over Earth's surface |
| B | E- Part of Stratosphere | II | Approximate 300 km over Earth's surface |
| C | F2- Part of Thermosphere | III | Approximate 10 km over Earth's surface |
| D | D- Part of Stratosphere | IV | Approximate 100 km over Earth's surface |
Choose the correct answer from the options given below:
- A.A-I, B-IV, C-III, D-II
- B.A-III, B-IV, C-II, D-I
- C.A-III, B-II, C-I, D-IV
- D.A-I, B-II, C-IV, D-III
Show answer and solution
Correct option: B
Solution
The atmospheric layers and their approximate altitudes are standard facts:
- Troposphere extends up to ~10 km → A-III
- E-layer (part of Stratosphere/lower ionosphere) lies at ~100 km → B-IV
- F2-layer (part of Thermosphere) is the highest ionospheric layer at ~300 km → C-II
- D-layer (lower part of ionosphere, sometimes grouped with stratosphere region) exists at ~65-75 km → D-I
This gives A-III, B-IV, C-II, D-I, which is option 2.
- Troposphere extends up to ~10 km → A-III
- E-layer (part of Stratosphere/lower ionosphere) lies at ~100 km → B-IV
- F2-layer (part of Thermosphere) is the highest ionospheric layer at ~300 km → C-II
- D-layer (lower part of ionosphere, sometimes grouped with stratosphere region) exists at ~65-75 km → D-I
This gives A-III, B-IV, C-II, D-I, which is option 2.
