Question:
Which one of the following is formed due to the dissolution of soluble rock?
Which one of the following is formed due to the dissolution of soluble rock?
Show Hint
When soluble rocks such as limestone, gypsum or dolomite are dissolved by groundwater, characteristic karst features develop. These form by chemical removal of rock material.

- Coastal landscapes
- Sinkholes
- Landslides
- Ash deposition
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
When soluble rocks such as limestone, gypsum or dolomite are dissolved by groundwater, characteristic karst features develop. These form by chemical removal of rock material.
Step 1:
Coastal landscapes form by marine erosion, landslides by mass movement on slopes, and ash deposition by volcanic activity. None of these is primarily caused by dissolution of soluble rock.
Step 2:
Sinkholes form when soluble rock beneath the surface is dissolved, creating an underground cavity that eventually collapses, producing a surface depression. This is a direct result of dissolution.
Answer: Option (2) — Sinkholes.
