The answer to the question" Give reason - it is easier to swim in a swimming pool than in a river .( only one answer ) "is-

In river has freshwater whereas in a pool there are salts and chemicals

Explanation:

Yes , it is easy to swim in swimming pool than river because -

• river has freshwater
• whereas in a pool there are salts and chemicals added to the water which makes it denser.
• River contains dissolved salts which makes its density more than river water
• Here upthrust is more in sea water than river water So it is easier to swim in sea water than in river water.
• The river has currents and rips.
• While a swimming pool is a still body of water, the river isn't.
• Part of its unpredictability are its currents and rips, which are not always visible before entering the water.
• If we swim out of a swimming hole into the river current we can be swept down the river by the force of the water.

These are the reasons why it is easier to swim in a swimming pool than in a river
