He claimed that each of the present continents was once joined together as part of a super continent called Pangea. He believed this because he saw that in certain areas continents would fit together for example the west coast of Africa fits together with the east coast of South America, therefore they must have moved apart from one central mass. Other evidence was shown to back up this theory such as the fact that glacier derived clays are found in all of the continents in Gondwana forming one half of Pangea, as one striations in rocks of Carboniferous age. Presently they cover half the globe but would form a reasonably sized polar ice cap if Wegener’s theory was true and the globe was reconstructed in his image of how it used to be. Despite Wegener having no concrete proof as to why this was the case his theory was proved to be accurate, physicists had believed that the earths crust was far from strong enough to be able to force itself apart.
3. The coldest temperature ever recorded was a negative 126.9 degrees fahrenheit in Vostok Station, Antarctica. 4. Between evaporation and falling as precipitation, a droplet of water may travel thousands of miles. 5.
The animals in the alpine biome are usually the warm blooded animals which accumulate layers of fat to insulate their bodies. The insects and some, very few cold blooded animals are usually hibernating or living under ground (Global Environment). This area has animals such as alpaca, mountain goats, chinchillas, condors, various insects, wolves, and arctic fox. Alpine biomes occupy high-mountain summits, ridges, and slopes above timberline. Because the alpine zone is present only on mountains, much of the landscape is rugged and broken, with rocky, snowcapped peaks, cliffs, and talus slopes, but also contains areas of gently rolling to almost flat topography (Biomes of the World).
Organism Physiology Paper: Rattle Snake April 16, 2012 The desert biome offers a unique ecosystem where organism must become accustomed to extreme temperatures ranging from the high 120 degrees in the summer to below 30 degrees in the winter. On top of extreme temperatures, organisms who live in this environment must also deal with dryness or low rainfall. Therefore, animals living in this ecosystem must adapt to withstanding very hot and very cold weather as well as surviving on the small food supply available in this environment. A prime example of this ecosystem is the Southwestern Desert. So what types of animals could possibly survive these harsh climate changes?
e. All of the above are correct. 8. All of the following are TRUE concerning the deepest part of the ocean except: a. The bottom of the trench was visited by Piccard and Walsh in the Trieste in 1960. b. The deepest part of the ocean is located in a trench south of Japan and north of Papua New Guinea c. The depth of the trench exceeds the height of Mount Everest.
What might happen to ice fish if the waters around the Antarctic became warmer? -They have a few methods of coping with the lack of hemoglobin. One mechanism being that they obtain oxygen from large capillaries throughout the fish, and its larger gills. It also has a much larger heart to help pump the blood throughout the body more efficiently. The lack of red blood cells keeps the fish from freezing and the viscosity of the blood is also lower.
Canada has very cold, bitter winters some parts of Canada are steppe. The U.S. and Canada are some what the same in Alaska most of the state is tundra like half the country in Canada. Also the US and Canada are mostly humid continental and our highlands like in the U.S. the Rockies and Appalachians and for Canada there Rockies and laurnatan highlands are cool or cold year around. The US and Canada have almost the same climate in parts of each country but also very different in some parts as
ii Going back to Vulpes zerda specifically, these desert dwellers are able to keep their internal desired temperature regardless of the fluctuation of the environmental heat through their endothermic characteristics. For this animal and other endotherms alike they are able to cool their bodies with rising temperatures and warm their bodies with low temperatures versus ectotherms that rely mainly on behavioral strategies to battle environmental changes. These carnivores are also described to be homeotherms which are animals that are capable of keeping a relatively constant temperature within their bodies. Insulation is a key component in thermoregulation of these homeotherms in which they are able to minimize the interaction of the environmental heat with their bodies. Burrowing is a common behavioral response of insolation in protecting themselves from the intensity of the heat and sun of the desert.
These are important to prove evolution. Convergent evolution includes three very important parts: (a) common ancestry, (b) speciation, and (c) natural selection. Evidence of a continental drift involvesis marsupials spreading across oceans that did not yet exist, making their travel across vast bodies of land possible. A key examplenother supporter of the a species that experienced continental drift is the Glossopteris. This tree was only able to grow in warm climates and had a seed that could not float, yet fossils of this tree are found in different hemispheres of the world today.
The Mount Kosciuszko supports a significant portion of Australia’s biodiversity including species of flora and fauna found only within the Mount Kosciuszko; pygmy possum, broad tooth rat and the spotted tail quoll. This variability provides for major breeding events of birds, fish and other fauna. Natural induces stress that has made the ecosystem of Mount Kosciuszko vulnerable is extreme strong winds, high rain fall, and high run-off falling snow-melt, large fluctuations of diurnal and seasonal temperatures and low mean temperatures. Having extreme weathering leads to loosening of soil which results in soil to be shallow, acidic and contain little organic matter which are easily
