Caspian Sea. Infrared satellite image of the northern part of the Caspian Sea and surrounding salt flats. North is at top. In the infrared range water is dark blue/black,bare ground is brown,salt flats are white/grey,and green vegetation is red. Salt flats occur in previously submerged areas. The Caspian Sea is the world's largest inland sea and has no outflows; water is lost only by evaporation. This evaporation leaves behind salts that were dissolved in the water. These form salt flats as sea level changes from year to year | |
