1. Define the following types of waterfalls and give one example of each.

In looking at waterfalls most often there can be different types represented in various stages of the fall. So you could have a plunge in the first 200m then a section of cascade for 30m vertical but 50m horizontal then a further plunge for 30m. A great example of this is the main waterfall in Yosemite National Park. This at my last look was the worlds 3rd highest.

These are the full list of waterfall types with brief descriptions but for the honour you only need to do those asked.

•Block: Water descends from a relatively wide stream or river.

•Cascade: Water descends a series of rock steps.

•Cataract: A large, powerful waterfall.

•Fan: Water spreads horizontally as it descends while remaining in contact with bedrock.

•Horsetail: Descending water maintains some contact with bedrock.

•Plunge: Water descends vertically, losing contact with the bedrock surface.

•Punchbowl: Water descends in a constricted form and then spreads out in a wider pool.

•Segmented: Distinctly separate flows of water form as it descends.

•Tiered: Water drops in a series of distinct steps or falls.

•Multi-step: A series of waterfalls one after another of roughly the same size each with its own sunken plunge pool.
