A Delta is shaped like a triangle , which is also the shape of the Greek letter D, called Delta. A river delta is caused by deposits at the mouth of the river. This happens when the river transports more slit to its mouth than can be removed by currents or tides.
The Mediterranean Sea has a very small tidal range , so big rivers like the Nile and the Rhone have very big Deltas. Deltas are less common rivers that flow to oceans and tidal seas.
