Matching Lines of Latitude: Tropics and Circles
This question asks us to match specific lines of latitude with their correct degree measurements and geographical locations (Northern/Southern Hemisphere or North/South of the Equator). Let's break down each term:
Understanding Key Lines of Latitude
- Tropic of Cancer: This is a line of latitude located in the Northern Hemisphere. It marks the most northerly latitude at which the Sun can be directly overhead. Its value is approximately $23\frac{1}{2}°$ North of the Equator.
- Tropic of Capricorn: This line of latitude is in the Southern Hemisphere. It signifies the southernmost latitude where the Sun can be directly overhead. Its value is approximately $23\frac{1}{2}°$ South of the Equator.
- Arctic Circle: Located in the Northern Hemisphere, this line marks the southern boundary of the Arctic region. It is situated at approximately $66\frac{1}{2}°$ North of the Equator. North of this line experiences at least one day of 24-hour sunlight and one day of 24-hour darkness annually.
- Antarctic Circle: This line of latitude is in the Southern Hemisphere. It is positioned at approximately $66\frac{1}{2}°$ South of the Equator and marks the northern boundary of the Antarctic region. South of this line experiences at least one day of 24-hour sunlight and one day of 24-hour darkness annually.
Matching Column-A with Column-B
Based on the definitions above, we can match the items:
- (a) Tropic of Cancer matches with $23\frac{1}{2}°$ in Northern Hemisphere (ii).
- (b) Tropic of Capricorn matches with $23\frac{1}{2}°$ in Southern Hemisphere (i).
- (c) Arctic Circle matches with $66\frac{1}{2}°$ North of the Equator (iv).
- (d) Antarctic Circle matches with $66\frac{1}{2}°$ South of the Equator (iii).
Therefore, the correct matching is (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii).
| Column-A Item | Column-B Match | Explanation |
|---|---|---|
| (a) Tropic of Cancer | (ii) $23\frac{1}{2}°$ in Northern Hemisphere | The Sun is directly overhead at noon on the summer solstice. |
| (b) Tropic of Capricorn | (i) $23\frac{1}{2}°$ in Southern Hemisphere | The Sun is directly overhead at noon on the winter solstice (in the Northern Hemisphere). |
| (c) Arctic Circle | (iv) $66\frac{1}{2}°$ North of the Equator | Marks the polar region in the Northern Hemisphere. |
| (d) Antarctic Circle | (iii) $66\frac{1}{2}°$ South of the Equator | Marks the polar region in the Southern Hemisphere. |
Choosing the Correct Option
Comparing our derived matches with the given options:
- Option 1: (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii) - This matches our findings.
- Option 2: (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii) - Incorrect.
- Option 3: (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv) - Incorrect.
- Option 4: (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i) - Incorrect.
The correct option that reflects the accurate matching is the first one.
