Question

There is higher salinity in the northern Red Sea while lower in the southern.

Answer 1

The Red Sea is one of the saltiest bodies of water in the world, owing to high evaporation.

The salinity is 36%o in the southern part because of the effect of the Gulf of Aden.

It reaches 41 %o in the northern part, owing mainly to the Gulf of Suez and the high evaporation as well as very little precipitation.

Hence, there is more salinity in the northern Red Sea while lesser in the south.
