Below are some examples of real life gorges and waterfalls...


Waterfalls - A waterfall has a very steep gradient, which causes the river to flow down it at a very high velocity. The rock type on the top tends to be hard rock and underneath soft rock. Additionally, a plunge fall often forms at the bottom of the waterfall where the gradient begins to level off.

Gorges - A gorge has very steep rocky walls which often have streams running through them.
