Caspian Sea
The Caspian Sea
has a surface area of about 143,630 square miles, making it the largest inland body of water in the world. Over 130 rivers empty into the Caspian Sea, with the Volga being the largest, but it has no outlets.
Glacers in General
Glaciers in General
A glacier is a huge mass of ice up to 10,000 feet thick that flows slowly over land. All glaciers begin to form when more snow falls during the winter than melts and evaporates in summer. The excess snow gets compacted into dense crystals of ice, and this ice eventually becomes so thick that it begins to move under the pressure of its own great weight.
Surtsey Island
Surtsey Island
dramatically rose up out of the waters off the southern coast of Iceland between November 14, 1963 and June 5, 1967. Formed by an underwater volcano, its highest point is about 505 feet above sea level.
