When a river reaches a lake or the sea the water slows down and loses the power to carry sediment .The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layers forming a delta.
Some deltas are so large that people can live on them. The Nile delta is a very important farming area in Egypt.
Deltas have a fairly flat section called a delta plain that is above water. The river cuts many small channels through the delta plain. These channels are called distributaries. New sections of delta build up at the mouths of the distributaries.
The rest of the delta is under water
There is a steeply sloping delta front that faces the lake or ocean. The prodelta is furthest away from the mouth of the river and is deepest under water.

In the reaction A + 2B ⇌ 2C, if 2 moles of A, 3 moles of B and 2 moles of C are placed in a 2 L flask and
the equilibrium concentration of C is 0.5 mol/L. The equilibrium constant (KC) for the reaction is.....and please tell how you know that the reaction is going forward .. imean how to calculate the reaction quotient ???
