Do waterfalls and rapids occur where rivers meet and flow over hard rocks ?

Answers

Answer 1

Answer: Waterfalls occur when there is a sudden drop. For example the land may be 40ft up, but then suddenly it drops to 10ft above sea level. Rapids occur when the water is running through a downhill slope with a bunch of rocks.
