describe the movement of water as a cascade
Answers
Answer:
Surface movement includes rivers, streams, creeks, lakes, ponds, and human-made "flood" control. All surface water is trying to reach sea level due to gravity. As water flows in channels, the streambed and banks of the channel will resist the flow of water. The velocity of the water is dependant on steepness of the slope, type of rock or soil, amount of vegetation, shape of stream bed, and obstructions. Surface water provides the liquid where most evaporation takes place.
Explanation:
A waterfall is an area where water flows over a vertical drop or a series of steep drops in the course of a stream or river. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf.
Waterfalls are commonly formed in the upper course of a river where lakes fall into in steep mountains. Because of their landscape position, many waterfalls occur over bedrock fed by little contributing area, so they may be ephemeral and flow only during rainstorms or significant snowmelt. The further downstream, the more perennial a waterfall can be. Waterfalls can have a wide range of widths and depths
