Geology Scholars and Theories Matching
This question requires matching scholars from List-I with their corresponding theories from List-II. Let's analyze each scholar:
Matching Scholars with Theories
| Scholar (List - I) | Theory (List - II) | Reasoning |
|---|---|---|
| (a) Hall and Dana | (iii) Theory of Geosyncline | James Hall and James Dwight Dana independently developed the concept of geosynclines to explain mountain formation. |
| (b) Hutton | (iv) Doctrine of Uniformitarianism | James Hutton, considered the father of modern geology, proposed that geological processes operating today are the same as those that operated in the past. |
| (c) Harry Hess | (i) Sea floor Spreading | Harry Hess proposed the theory of sea-floor spreading in the early 1960s, suggesting that new oceanic crust is formed at mid-ocean ridges. |
| (d) Jeffrey | (ii) Thermal Contraction Theory | Sir Harold Jeffreys proposed the Thermal Contraction Theory to explain the origin of continents and mountains, although it has been largely replaced by plate tectonics. |
Correct Matching and Code
Based on the individual matches:
- (a) corresponds to (iii)
- (b) corresponds to (iv)
- (c) corresponds to (i)
- (d) corresponds to (ii)
This combination corresponds to the code (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii).
