Here is another possible casual chain that might be used. I haven't had a chance to look over the rough draft very much. I have a basetball game tonight. I will try and look at it later tonight or tomorrow. Maybe this chain can be of some help.
L>H>L>H>E>H>B: (L) The Earth is made up of large bodies of land called continents. Their surfaces vary from low, green valleys to high, rocky mountains where almost nothing grows. Antarctica, the continent at the South Pole, is almost completely under ice and snow. The Transantarctic Mountains cross the entire continent. The mountains are made up of several ranges. Some peaks rise more than 14,000 feet. The Transantarctic Mountains divide the continent into two natural land regions. The land formation allows ice streams (H) to reach the coast and push out across the ocean. It passes over rocky terrain, (L) anchoring to irregular rocks to form a hinge. The ice continues to grow outward into the water. (H) The result is a large; floating shelf of ice affixed to the continent called shelf ice. (E) Ice shelves are made up of continental ice and glaciers, which are slowly floating into the sea. They are usually 100’s meters. They lose mass primarily by ice calving. Changing in the volume of water equal to the volume of water it contains. Ice shelves cover fifty percent of the Antarctic coast. The surface of all ice shelves added together is more than one-tenth the size of the continent. The largest individual ice shelf is the Ross Ice Shelf in West Antarctica, also called the Great Ice Barrier. It is as big as France and fed by not less than seven ice streams. (H) Snowfall and glaciers that slide off land will nourish it. Eventually the outermost parts of healthy ice shelves crumble into icebergs during the warm summer, helped by storms and tides, Icebergs can be extremely dangerous to people. (B) During the night of April 14 and 15 1912 one of the greatest sea disaster in history occurred when the Titanic struck an iceberg, around 1,500 people were killed. This disaster lead to the establishment of the International Ice Patrol. The patrol reports the position of icebergs and estimates their probable courses. There is little humans can do to control icebergs. Ships can not approach them because the submerged parts my tear open the ship’s bottom. http://www.earthsky.com http://www.asoc.org/general/iceshelve.html http://www.greenpeace.org
