water erosion

waterfalls natural levees meandering streams 0X- BOW LAKE Braided stream river deltas lagoons caves , arches , stacks cliffs

A levee is a natural or artificial wall that blocks water from going where we don’t want it to go.

when a river flodts and deposits sand / sediment on the side if river bank The banks of a river are often slightly elevated from the river bed.

A meander is a bend in a river channel.

Meanders form when water in the river erodes the banks on the outside of the channel.

erosion involves the movement of sand and soil particles from one location to another deposition is when those sand and soil particles moved by erosion , is deposited in places on land

a curved lake formed, when it had been cut off from the the meandering stream, by erosion

erosion makes the neck narrow during floods the river take the shortest coarse through the meander neck this cuts off the meander from the main stream and it forms a ox bow lake

A river with multiple channels separated y sand or gavel bars or (islands )

braiding form by deposition of sand or gravel bars in mid-channel

forms at the mouth of a river where it opens into the ocean

forms from deposition of sediment carried by a river as the flow leaves its mouth

caves , arches , stacks

• large crack , opened up by hydraulic action • the crack group into a cave, by hydraulic action and abrasion • cave becomes bigger • the cave breaks through the headland forming a natural arch • the arch is eroded and collapses • this leaves a tall stack 7 stack erodes foring a stump
