Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
The portion west of the Weddell Sea and east of the Ross Sea is called West Antarctica and the remainder East Antarctica, because they roughly correspond to the Western and Eastern Hemispheres relative to the Greenwich meridian.
In the dry valleysthe same effect occurs over a rock base, leading to a desiccated landscape. The sheet has been of recent concern because of the small possibility of its collapse.
If the sheet were to break down, ocean levels would rise by several metres in a relatively geologically short period of time, perhaps a matter of centuries. Antarctica contains many other mountainson both the main continent and the surrounding islands.
Another well-known volcano is found on Deception Islandwhich is famous for a giant eruption in Minor eruptions are frequent, and lava flow has been observed in recent years.
Other dormant volcanoes may potentially be active. It was once believed that the lake had been sealed off forto one million years, but a recent survey suggests that, every so often, there are large flows of water from one lake to another.
If life is discovered in Lake Vostok, it would strengthen the argument for the possibility of life on Europa. If found, these resilient creatures could further bolster the argument for extraterrestrial life in extremely cold, methane-rich environments.
Geology of Antarctica Subglacial topography and bathymetry of bedrock underlying Antarctica ice sheet The above map shows the subglacial topography of Antarctica. As indicated by the scale on left-hand side, blue represents portion of Antarctica lying below sea level. The other colours indicate Antarctic bedrock lying above sea level.
Map is not corrected for sea level rise or isostatic reboundwhich would occur if the Antarctic ice sheet completely melted to expose the bedrock surface. Topographic map of Antarctica after removing the ice sheet and accounting for both isostatic rebound and sea level rise.
Hence, this map suggests what Antarctica may have looked like 35 million years ago, when the Earth was warm enough to prevent the formation of large-scale ice sheets in Antarctica.
Antarctica was not always cold, dry, and covered in ice sheets. At a number of points in its long history, it was farther north, experienced a tropical or temperate climate, was covered in forests, and inhabited by various ancient life forms.
Palaeozoic era — Ma During the Cambrian periodGondwana had a mild climate. West Antarctica was partially in the Northern Hemisphereand during this period large amounts of sandstoneslimestones and shales were deposited. East Antarctica was at the equator, where sea floor invertebrates and trilobites flourished in the tropical seas.
Sand and silts were laid down in what is now the EllsworthHorlick and Pensacola Mountains. During the Permian period, the land became dominated by seed plants such as Glossopterisa pteridosperm which grew in swamps. Over time these swamps became deposits of coal in the Transantarctic Mountains.Unit 6A: The U.S.
