SALINITY OF RED SEA.

Red Sea

has the highest salinity!

Furthermore, in 1949, an underwater research reports hot brine, in the central portion of red sea. Research in 1960's conforms the presence of hot temperature reaching 60 degrees Celsius. The hot solution came out of seafloor rift, and salinity was so high, that it was so hard for an organism to live.

Our Conclusion/Prediction

Evaporation, hydrothermal vents, and sea floor rift, are mainly the solid proof that why is red sea the saltiest water on Earth.

Our prediction is that overtime, red sea will be way more wider than it is , due to the rift, and due to that, many more hydrothermal vents will be born, making red sea the saltiest water in the future too.

So Much Salt!

Red sea is a body of water, made by split of tectonic plate, African and Arabian, as shown in figure 2 and it will one day become an ocean, as the rift is still going on.As red sea is near the equator, a lot of water evaporates. 205cm or 81in per year, as it doesn't precipitation that much, it only rains 0.06m or 2.36in per year. So most of the water goes away in evaporation, and no fresh water comes back as precipitation as shown in figure1. so it means that the concentration of salt is a lot higher and that makes it the saltiest water.

Sea floor Rift!

The Red Sea is actually rifting apart, taking the African plate away from arabian plate, as shown in figure 7 ,8 and Figure 9 extending the area of red sea like a "V" shape. This shows that there might be many hydrothermal vents under Red Sea.

Hydrothermal vents under red sea!

Sometimes during the Tertiary period the Bab el Mandeb

Shown in figure 2, a part of red sea, evaporated to an empty, hot, dry salt-floored sink.

We have found in our research hydrothermal vents, that is a great source of salt. Hydrothermal vents are vents under water that throw out gas and magma, explained with picture in figure 3 including minerals, such as salt too.

There is a rift under red sea (explained in next slide) and there is a land emerging from under water, those islands are called "Zubairs Islands", as shown in figure 4 and, and there are volcanoes on it. which shows that they were once underwater, and part of hydrothermal vents.
