During the winter for many years penguins had to face some of the harshest climate changes in Antarctica; This alone will be the cause of functional adaptation and the start of evolutionary changes. These changes added to the challenges which they endured each winter for survival. These penguins would walk miles to get to the nesting grounds a place where it was safe for them to mate and live with their nuclear family. The nesting grounds was miles away from the shore end so penguins would have to

* 2. The opening scene shows the collapse of a massive ice shelf (a floating glacier) in Antarctica. Could this really happen? If so‚ how might this affect global sea levels? Happens all the time‚ always has. Only affects sea level if the rate of ice shelf collapse increases or decreases significantly over a long period of time. 3. Is it realistic to think our climate is in a fragile state? What does burning fossil fuels have to do with global warming ice caps? Oil and gas are hydrocarbons

The Antarctic Circumpolar Current (ACC -- also the "West Wind Drift")‚ flows in the Southern Ocean around Antarctica‚ and nothing gets in its way. It’s the strongest current on Earth. People may be expecting else to take you "around the world" but that is the correct answer. Always flowing from west to east. 4. If you were traveling from South America to Labrador

depth of 6‚500 feet and the fact that the region contains around seven million cubic miles of ice that allows the Antarctic to be classified as an extreme environment (Mulvaney‚ 1997). As it is an extreme environment‚ any living organisms found in Antarctica will have to deal with these harsh conditions. Despite all of this however‚ quite a few living organisms can still be found throughout the Antarctic. These living organisms are able to survive as they have adapted themselves to suit the conditions

Arctic Sea Melting Enhancing the Effect of Global Warming in High Latitudes The world warmed by about 0.7°C in the 20th century. Every year in this century has been warmer than all but one in the last century (1998). If carbon-dioxide levels were magically to stabilize where they are now (almost 390 parts per million‚ 40% more than before the industrial revolution) the world would probably warm by a further half a degree or so as the ocean‚ which is slow to change its temperature‚ caught up.

BONE-EATING WORMS FROM THE ANTARCTIC: the contrasting fate of whale and wood remains on the Southern Ocean Seafloor OLUDAMILOLA ADESIYUN GEOL 440 DR. CARL RICHTER NOVEMBER 17‚ 2013 This paper explains the results from the first experimental study of the fate of whale and wood remains on the Antarctic seafloor. Using a baited free-vehicle lander design‚ it is observed that whale-falls in the Antarctic are heavily infested by at least two new species of bone-eating worm‚ Osedax antarcticus

Continental Drift Were the continents of this planet always situated the way they are today? Could there have been one supercontinent that over time broke off into the continents we know now? Merriam-Webster Dictionary defines Pangaea as a hypothetical land area believed to have once connected the landmasses of the southern hemisphere with those of the northern hemisphere (Definition of Pangaea). This theory‚ discovered by Alfred Wegener‚ was known as the drift theory. Wegener used the fit of the
