Answers
Answer:
Formation of Beaches
Sea waves strike the coasts.
They erode the coasts and carry the eroded material in the form of silt and other material.
When they withdraw they deposit the silt and other material (sediments) along the shore, forming wide beaches.
Ox-Bow Lakes
When the meander loop is cut-off from the main river, it forms a cut-off lake.
Its shape is like an ox-bow.
Hence, the cut-off lake is called ox-bow lake.
Explanation:
Answer:
Beaches are formed when waves deposit sand and gravel along the shoreline. Some beaches are made up of pebbles and rock. Over time, they are rolled out smooth by the waves.
An oxbow lake is a U-shaped lake that forms when a wide meander of a river is cut off, creating a free-standing body of water. In south Texas, oxbows left by the Rio Grande are called resacas. In Australia, oxbow lakes are called billabongs.
