Why does a waterfall never stop flowing?
It’s because it has a small catchment area. The water comes from wherever the river is fed from. It’s mainly rain but some come from springs in the ground. Some actually do run out of water.
Why do waterfalls create mist?
At Niagara Falls, water roars over the edge and hits the water and rocks below, smashing into tiny droplets. When the water temperature is warmer than the air, the droplets mix with the air and warm it. Those temperature differences make more mist, Dr.
How is a waterfall formed GCSE?
A waterfall is a sudden drop along the river course. It forms when there are horizontal bands of resistant rock (hard rock) positioned over exposed, less resistant rock (soft rock). The soft rock is eroded quicker than the hard rock and this creates a step. Abrasion and hydraulic action erode to create a plunge pool .
How does a river never run out of water?
A river that does not run dry at any time of year is carrying surplus water from precipitation that collects in the permeable rocks of hills and mountains that surround the watershed. Most rivers get their water from the mountains, where there is far more precipitation than over the lowlands.
How do lakes not run out of water?
For a lake to keep its water over time, it has to be replenished. The main way that water gets into reservoirs and man-made lakes is from the rivers and streams that were dammed to create them. Like man-made reservoirs and lakes, natural lakes may also be replenished by rivers and streams.

How are rapids formed?
They are formed when the water goes from one hard rock that resists the water’s erosion to a softer rock that is easier eroded. The debris formed by the erosion breaks up the flow of the river, but are not big enough to form a waterfall. Over time, rapids are formed.
How does a waterfall formed step by step?
Formation of a waterfall:
- The soft rock erodes more quickly, undercutting the hard rock.
- The hard rock is left overhanging and because it isn’t supported, it eventually collapses.
- The fallen rocks crash into the plunge pool .
- Over time, this process is repeated and the waterfall moves upstream.
How does a waterfall formed?
Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them.
Do rivers ever dry up?
So, rivers can dry up when there is drought . The is called the water cycle . Water evaporates from the oceans forming clouds in the atmosphere which blow over the land and precipitate , filling the rivers with water which flows downhill back to the ocean.
