Question

What is the difference between the following: Waterfall - Rapids

Answer 1

Rapids and waterfalls

Rapids are stream sections with extremely strong currents, numerous obstacles, and steps in their streambeds. A waterfall is a vertical drop in a streambed. Both are sites of vigorous erosion . Rapids often form where resistant bedrock confines a stream to a narrow channel, and forces an increase in water velocity. Fast-moving water, laden with abrasive sand and gravel, cuts into the bedrock, forming cliffs on either side of the cataract. Large boulders fall from the cliffs, creating obstacles in the streambed, and increasing water turbulence. Rapids are navigational hazards that have hampered exploration, travel, and trade on the world's rivers throughout human history.

Answer 2

Answer:

       Waterfall and Rapid are different from the sides of their formation and the flow.

     Due to increase in water flow Rapid forms and due to sudden break in elevation of a rock Waterfall forms. Rapid is created by factors like gradient, construction, obstruction and flow rate. Waterfall causes by falling of the water of steep, vertical drop and a plunge pool.
