Natural cracks in the rock that form due to the exhumation of deeply buried rock are called salt wedges.
Answer: Option 1
<u>Explanation:
</u>
The process of exhumation in the discipline of Geography refers to digging up of a buried rock due to natural forces applied on the surface under which the rock is buried. At a salt wedge, a river flowing with a great velocity meets the ocean where the ocean is comparatively calm.
The fast-flowing river water acts as a digging force and carries out the process of exhumation of the rocks at the wedge. The same fast-flowing water creates cracks in the exhumed rocks.
