Which among the following are exogenic geomorphic processes?

(A) Weathering

(B) Diastrophism

(C) Erosion and deposition

(D) Mass movement

Choose the correct answer from the options given below:

Option 1 -> Includes Diastrophism (B), which is an endogenic process driven by internal Earth forces, not exogenic.

Option 2 -> Includes Diastrophism (B), which is an endogenic process involving crustal deformation, not exogenic.

Option 3 -> Includes Diastrophism (B), which is an endogenic tectonic process, not exogenic.

Option 4 -> Correctly identifies only exogenic processes: Weathering (breakdown of rocks by atmospheric agents), Erosion and deposition (surface processes by water, wind, ice), and Mass movement (gravity-driven downslope movement).

Hence, Option 4: (A), (C) and (D) only -> Exogenic processes are external processes occurring at or near Earth's surface driven by solar energy, gravity, and atmospheric agents. Diastrophism (B) is an endogenic process driven by internal Earth forces involving tectonic deformation, while weathering, erosion/deposition, and mass movement are all exogenic surface processes -> correct
