Comparison Between the Rea Sea and the Black Sea
|Criteria||Red Sea||Black Sea|
|Location and Facts||- The Red Sea is a salt water inlet of the Indian Ocean between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb. In the north are the Gulf of Aqaba, and the Gulf of Suez
- Area: 438,000 km2
- Water volume: 233000 km3
- Average depth: 532 m
- Length: 2,250 km
- Width: 355 km
|- The Black Sea is an inland sea bounded by southeastern Europe, the Caucasus and Turkey
- Area: 436,400 km2
- Water volume: 547000 km3
- Average depth: 1253 m
- Length: 1,175 km
|Climate||- The red Sea is surrounded by extremely hot arid deserts on all shores, that receives very little precipitation in any form||- A steppe continental climate, with cold humid winters and hot, dry summers|
|Rivers and Salinity||- No rivers supply the Red Sea with fresh water, this along with high rate of evaporation and very little precipitation, makes the Red Sea one of the most saline water bodies in the world, with salinity reaching 3.8%.
The microalgae concentration is very low, causing very clear visibility in the Red Sea, which is 200 meters
|- Freshwater flows in from the European areas. The most important river entering the Black Sea is the Danube, followed by the Dnjestr and the Dnepr, these contribute to decreased salinity
The surface water has an average salinity of 1.8% and contains oxygen and other nutrients required to sustain biotic activity.
The microalgae concentration is much richer than the Red Sea, causing the dark colour. Visibility in the Black Sea is only 5 meters, compared to the excellent visibility of 200 m in the Red Sea!
|Human Settlements||- Very hard living conditions on the shores of the sea with no rivers supplying fresh water
- Historically the virgin costal areas had very few human settlements
|- Important cities and civilizations flourished along the coasts of the Black sea.
The Sea was navigated and its shores colonized by Greeks and Romans as early as the eighth century BC
- Troy, Constantinople, Istanbul, Sevastopol, Odessa, and Yalta are examples of historical cities in this coastal area.
|Historical Role||- Natural border between Egypt and the Arabian Peninsula, with no connection between its arid uninhabited coasts on both Asian and African shores
- The earliest known exploration expeditions of the Red Sea were conducted by Ancient Egyptians seeking to establish commercial routes to Punt.
Expeditions were ordered by Pepi 2 at 2200 BC during the Old Kingdom, Mentuhotep 3 at 2000 BC during the Middle Kingdom, and at 1500 BC led by Hatshepsut during the New Kingdom
- In the bible story Moses led the children of Israel out of Egypt, with the Pharaoh and his army chasing him. Moses was in a difficult spot, on either side were high mountains. in front was the Red Sea. And coming up fast behind was Pharaoh and his army. The lord told Moses to lift up his staff and stretch it out over the Red Sea, a strong wind to blow all night, and the water of the sea divided left and right, and a dry path down the middle. Moses and the children of Israel went through easily. When Pharaoh saw this he decided to cross over on the dry path. Moses lifted up his staff and stretched it out over the water, and the water came crashing back, all of Pharaoh's army was drowned.
|- Has been of critical importance to regional commerce throughout the
ages, linking Europe with Asia.
- Many of the colonial and commercial activities of ancient Greece and Rome, and of the Byzantine Empire, centered on the Black Sea
- Among its vast historical riches, the Black Sea region is home to the legend of Jason and the Argonauts and their search for the Golden Fleece, and the Biblical account of Noah's Ark.
|Fauna||- Due to small human populations, and extensive shallow shores. The sea has a rich and diverse ecosystem of over 1,000 marine invertebrate species and 200 soft and hard marine corals
- Coral reefs are 5000-7000 years old
|- Heavily overfished and overcrowded. many fish have disappeared and other fish stocks have declined from the Black Sea habitats.|
