What is a water delta?
a mouth or delta
Fresh water flows into the sea at a place called the river delta. Depending on the geography of the delta, over time, the waters mix and the composition of the delta water establishes its unique saline content. The saline content of the delta is lower than the saline content of the sea and higher than the saline content of the river, which should be zero. You can read more about river deltas, below.
A delta develops when a river flows into a larger body of water because the the river water is no longer flowing downhill. +++ A delta develops where there are no significant cross-currents in the lake or estuary to carry away the silt carried down by the river. As the river slows its suspended sediment falls to the bed, building the fan-shaped delta upwards to near-surface, and outwards. (:
In a bath 30kg of cold water at 20 degrees centigrade is added to 10kg of water at 60kg What is the temperature of the water Please explain in simple terms?
The 60kg in the above statement should be 60 degrees centigrade. It is common to use the term Celsius instead of centigrade. The First Law of Thermodynamics can be applied to the mixing of the cold water and the hot water. They eventually come to thermal equilibrium at a temperature, TE. Q = ( Delta UCW ) + ( DELTA UHW ) + WB Assume perfect insulation. -----> Q ~ 0.0 There is no work…
Deltas are complex depositary features which are formed at the mouths of rivers. Some major deltas are the Nile delta in Egypt, the Mississippi delta in the USA and the Ganges delta in Bangladesh. They mainly form because the velocity of a river slows where the fresh water mixes with the salt water of the sea and the reduction of velocity causes sediment carried by the river, the heaviest sediment first.
