A waterfall generally forms under which condition?

Answer and explanation

Correct answer: When hard and soft rocks differ in the river bed

The correct answer is B. A waterfall commonly develops where resistant hard rock and less resistant soft rock occur together in the river channel. The soft rock is worn away more rapidly, while the hard layer remains as a step or ledge; continued erosion increases the drop. A plain, wind deposition, and retreating sea waves do not create this river-bed contrast.
