Question

Give reason.

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

Answer 1

• The Red Sea is a conical, long sea in the peninsula of North-East Africa and Arabia. The northern part of this sea is surrounded by landslides, while its southern part is in the Indian Ocean.
• Therefore, the flows of the Indian Ocean have a direct impact on the southern part of the Red Sea, which balances the alkali here and reduces the resulting alkali.
• Near the Sahara Desert and Arabian Desert, there are higher temperatures and vaporia in the northern region. This causes more salinity.
