Question

2.
How would you differentiate between.
fresh water and saline water​

Answer 1

Answer:

Salt water is water that contains a certain amount of salts. This means that its conductivity is higher and its taste much saltier when one drinks it. ... Freshwater is water with a dissolved salt concentration of less than 1%.

Answer 2

Answer:

When river water meets sea water, the lighter fresh water rises up and over the denser salt water. Sea water noses into the estuary beneath the outflowing river water, pushing its way upstream along the bottom. Often, as in the Fraser River, this occurs at an abrupt salt front.
