Question

Why is the northern part of the Red Sea more saline than its southern part?

• A. The northern part of the Red Sea recieves water from Gulf of Suez.
• B. The rate of evaporation is lower in the northern part of the Red Sea.
• C. The nothern part of the Red Sea is a landlocked sea.
• D. Salinity and temperature currents of Indian Ocean largely regulate the salinity and temperature of southern end.

Answer 1

Answer: (A), (C), (D)

Salinity and temperature currents of Indian Ocean largely regulate the salinity and temperature of southern end.

The northern part of the Red Sea is more saline than the southern part maily due to the Gulf of Suez that which lies to the west of the Sinai Peninsula. The water from the Gulf of Suez is known to have a salinity of about 40 parts per thousand. The northern part is a landlocked sea. It is surrounded by Sahara and Arabian desert. A relatively higher rate of evaporation in the northern part of Red Sea makes it more saline.

The southern end of the sea is towards the Indian ocean. The ocean currents of Indian Ocean largely influences the salinity and temperature of southern part of the Red Sea.
