Landforms Flashcards
What is fluvial erosion? (Landforms rivers)
the bed and banks are broken down by different processes
What is fluvial deposition? (Landforms rivers)
the process of dropping eroded material
What are v-shaped valleys? (Landforms rivers)
vertical erosion, river takes a winding course due to the highland areas that jut out
What are waterfalls? (Landforms rivers)
River flowing over a rock that is not uniform, soft rock will lead to undercutting and a plunge pool at the base
What are patholes? (Landforms rivers)
fast flowing water swirled and small particles wear at depressions which gradually become deeper
What are rapids? (Landforms rivers)
A series of short and fast falls, the water is very shallow and flows quickly over rocks
What are meanders? (Landforms rivers)
loop-like bends in the middle course that generally form when erosion is on the outside bank
What are ox-bow lakes? (Landforms rivers)
Recent shaped
form when meanders become so pronounced that they cut off from the main river
What is braiding? (Landforms rivers)
Rivers that have been multiple channels and islands of sediment in between
What are leeves? (Landforms rivers)
If a river floods, material is deposited on the banks, creating natural embankments
What are deltas? (Landforms rivers)
Pieces of flat land are made of layers of sediment deposited at the river mouth over time
