When endogenetic forces act horizontally from the opposite directions causing compression and tension the resultant landform is a large dome shaped structure , the process is called

• Folding

• Faulting

• Fracturing

• Warping

Which one of the following explanations of the origin of pediments was first propounded by A.C.Lawson (1915) ?

• Sheet flood deposition

• Horizontal erosion

• Recession of mountain front

• Lateral erosion

ASSERTION (A) : By far the most common and widespread topographic form in a karst terrain is the sinkhole.

REASON (R) : Topographically , a sinkhole is a depression that varies in depth from less than a metre to few hundred metres.

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true but (R) is not the correct explanation of (A).

• (A) is correct , but (R) is false.
