Question

How are waterfalls formed?(1mark​

Answer 1

Answer:

The process of formation of waterfalls happens when a stream flows from soft rock to hard rock. This happens both laterally and vertically. In every case the soft rock erodes and leaves the hard rock as it is.

Answer 2

Explanation:

waterfalls are formed in the upper course of rivers. This is the place where lakes start to fall into steep areas, such as mountains. Many waterfalls form over bedrock that is not assisted by the surrounding area due to their landscape positioning. These waterfalls are often short-lived and only flow during snowmelt or rainstorms. However, the more we move downstream, waterfalls become more enduring.
