Matching Meteorological Terms
This question requires matching terms from List - I with their corresponding definitions in List - II. These terms are used in meteorology and oceanography to represent lines connecting points of equal value.
List - I and List - II Definitions
Let's analyze each term:
- (A) Isohel: Derived from 'Helios' (sun), an Isohel line connects places with equal duration of sunshine. Thus, (A) matches with (III).
- (B) Isohyet: Derived from 'Hyetos' (rain), an Isohyet line connects places with equal amounts of rainfall over a specific period. Thus, (B) matches with (IV).
- (C) Isoneph: Derived from 'Nephos' (cloud), an Isoneph line connects places with equal cloud cover. Thus, (C) matches with (I).
- (D) Isohaline: Derived from 'Hals' (salt), an Isohaline line connects places with equal salinity, often used for ocean water. Thus, (D) matches with (II).
Correct Matching
Based on the analysis, the correct matching is:
| List - I Item | List - II Item | Explanation |
| (A) Isohel | (III) Sunshine | Equal sunshine duration |
| (B) Isohyet | (IV) Rainfall | Equal rainfall amount |
| (C) Isoneph | (I) Cloud cover | Equal cloud cover percentage |
| (D) Isohaline | (II) Salinity in the ocean | Equal salinity level |
Therefore, the correct option is the one that represents the matching (A)-(III), (B)-(IV), (C)-(I), (D)-(II).
