How is a delta created? by sediments deposited on either side of river banks by sediments deposited by winds over large areas by sediments deposited when a glacier melts by sediments deposited when a river flowing from mountains empties into an ocean

Answer 1

A delta is primarily created by sediments deposited when a river flowing from mountains empties into an ocean, sea, or lake. As the river approaches its mouth, the flow of water slows down, and sediments that have been carried by the river are dropped, forming a delta. This deposition occurs because the river can no longer transport the sediment due to the decrease in water velocity, leading to the accumulation of these materials at the river's terminus. Over time, these sediments build up and create the characteristic fan-shaped or triangular landform known as a delta.
