Give geographical reasons:All rivers do not form delta. |

Answer» All rivers do not form delta because – 1. Delta is a place near the seashore where the sediments brough down by a river are deposited in triangular form. 2. Most of the rivers finally join to the sea but every river does not form delta because they do not have the huge load of sediments. 3. If the rivers are travelling from a long distance, they join many tributaries and they deposit the sediment into the main river. Such long and sluggish rivers can deposit sediment at the river mouth and form delta. For example, The River Ganga has formed a huge delta. 4. Some rivers are short and swift. They do not receive more tributaries, so such rivers have less sediments. These rivers flow very swiftly so they deposit sediments in the sea water. Therefore, they do not form delta. |
