D.《1》☀️When a map is made, scaling down the distance on the ground to that of the map is essential.
☀️Representative fraction or RF helps to establish a ratio between the two.
☀️Thus RF has the universal application of making maps.
《2》☀️When this mid-channel bar is deposited at the mouth of a river, the flow is routed around it.
☀️This results in additional deposition on the upstream end of the mouth-bar, which splits the river into two distributary channels.
☀️A good example of the result of this process is the Wax Lake Delta.
