what factors lead to the formation of a delta?
Answers
Answer:
the deposition of sediments from the rivers and its tributaries leads to form the delta.
Answer:
• The formation of a delta depends on the amount of sediments that river carries, the size of the sediments it carries , and the speed of the flow of river.
Explanation:
• Deltas are the wetlands which are formed when river water meets other bodies of water such as Seas, and Oceans.
• The river in its upper course flows with high speed and causes large scale erosion.
• The sediments carried by the river flows along with the river and is deposited in the lower course of the river.
• The amount of sediments are so large that the river forms many branches and forms numerous channels of river.
• The sediments settle according to their sizes, that is the largest sediment particles settle at the bottom while the smaller ones in the upper layers.
• If the amount of sediments carried by the river is large, then the chances of this river forming delta is much larger.
• It is also determined by the size of the sediment particles.
• And lastly it depends on the speed of flow of the river. If the speed of flow is slower than there is more chances of formation of delta.
