Question

Match List - I with List - II 

List - I	Meaning / Type	List - II	Description
A. Deluvium	Mass wasting deposits	I	Deposits formed by mass wasting
B. Eluvium	In-situ weathering products	II	Residual products of the breakdown of primary rocks
C. Proluvium	Flash flow deposits	IV	Sediments deposited by mudflows and other flash flows
D. Colluvium	Gravity transported materials	III	Residual products of the breakdown of mobile rocks

• A. A-II, B-III, C-IV, D-I
• B. A-II, B-III, C-I, D-IV
• C. A-III, B-IV, C-II, D-I
• D. A-III, B-I, C-IV, D-II

Hint:

Colluvium is related to mass wasting, while proluvium is related to mudflow and flash-flow deposits.

Answer 1

The Correct Option is A

Concept:
Superficial deposits are classified according to their origin and mode of transport. Some are residual, while others are transported by mass wasting, mudflow or flash flow.

Step 1: Match Deluvium.
Deluvium is matched with residual products formed by breakdown of primary rocks in the given classification. \[ A\rightarrow II \]

Step 2: Match Eluvium.
Eluvium is matched with residual products formed by breakdown of mobile rocks in the given list. \[ B\rightarrow III \]

Step 3: Match Proluvium.
Proluvium is commonly associated with sediments deposited by mudflows and flash flows. \[ C\rightarrow IV \]

Step 4: Match Colluvium.
Colluvium is commonly formed by mass wasting on slopes. \[ D\rightarrow I \] Therefore, the correct matching is: \[ A-II,\ B-III,\ C-IV,\ D-I \] \[ \therefore \text{Correct Answer is (A)} \]
