The Red Sea contains some of the worldâ€™s warmest and saltiest seawater â€“ that's the result of high levels of evaporation by the hot dry climate. Normally the sea is the intense blue-green that you see here, but algal blooms sometimes form and turn the sea a reddish color when they die off. (Image captured by Sentinel-2A in June of this year)
A note for those interested in geology: The Red Sea lies in a fault separating two blocks of Earthâ€™s crust â€“ the Arabian and African plates.Â
