Waterfall
A wwaterfall is an area where water flows over a vertical drop or a series of steep drops in the course of a stream or river.

  • Tiered: Water drops in a series of distinct steps or falls.
  • Punchbowl: Water descends in a constricted form and then spreads out in a wider pool.

Valley
A valley is a low area between hills or mountains typically with a river running through it.
  • River Valley: Formed by the erosive action of water flowing over the land.
  • Glacial Valley: Due to breadth and weight of glaciers, these valleys are wider and have flat bottoms with a contour similar to a "U"
  • Flat-floored Valley: Most common type of valley in the world. Over time rivers and streams spread across the valley (either River or Glacial), persistently eroding its edges.
