Answer 2

$\huge\underline\bold\purple{★ ANSWER :}$

A waterfall is a sudden drop along the river course. It forms when there are horizontal bands of resistant rock (hard rock) positioned over exposed, less resistant rock (soft rock). The soft rock is eroded quicker than the hard rock and this creates a step. This process continues and the waterfall retreats upstream.
