1.How is delta formed? Draw a neat and labelled diagram of delta.
2.Explain the depositional work of glacier.
3.Explain the erosional and depositional work of wind.please dont answer unneccessary (reported)
Answers
1When a river reaches a lake or the sea the water slows down and loses the power to carry sediment. . The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layers forming a delta.
2When a glacier passes through the ice tunnels and deposits the sediments at a distance or in simple words when a glacier make its last moraine.
3Wind can carry small particles such as sand, silt, and clay. Wind erosion abrades surfaces and makes desert pavement, ventifacts, and desert varnish. Sand dunes are common wind deposits.
Answer:
1)Delta it is a triangular landform that a river form near mouth( where it meets the ocean or sea) the river deposits most of its elements near the mouth this deposit sediment force the river to split into several distributors and the resulting collectively known as dalta
2) glacial deposition and is the sitting of sediment left Behind by moving glacier As glaciers move over land tthey pick up the sidiment deposits carried by the glacier is called glacial till.piles of till deposited along the edges of the mixture of unsorted sediment deposited along the edges of past glaciers are called moraines.
