Match the LIST-I  with LIST-II

LIST-I (Theories)		LIST-II (Propounders)
A.	Turbidity Current	I.	W.M. Davis
B.	Submarine Density Current	II.	Lawson
C.	Subaerial Erosion	III.	Holimann
D.	Diastrophic	IV.	J.D. Dana

Correct option is A

1. Turbidity Current – W.M. Davis (A-I) 

   • Turbidity currents are underwater flows of sediment-laden water that move downslope due to gravity.
   • W.M. Davis, known for his geomorphological contributions, studied such processes in coastal and marine environments.

2. Submarine Density Current – Holimann (B-III) 

   • Submarine density currents occur due to variations in water density, driven by temperature and salinity differences.
   • Holimann contributed significantly to understanding these currents and their role in underwater sediment transport.

3. Subaerial Erosion – J.D. Dana (C-IV) 

   • Subaerial erosion refers to landform changes due to weathering, water flow, and wind erosion.
   • J.D. Dana contributed to the study of continental and coastal landform evolution.

4. Diastrophic Theory – Lawson (D-II) 

   • Diastrophism refers to deformation of the Earth's crust, including folding, faulting, and mountain building.
   • Lawson studied crustal movements and their impact on geological structures.

Thus, the correct matching is:
A-I, B-III, C-IV, D-II
