Integrated geography Environmental geography is concerned with the description of the spatial interactions between humans and the natural world. It requires an understanding of the traditional aspects of physical and human geography, as well as the ways that human societies conceptualize the environment.
Two factors make it difficult to study the geology and mineral resources of Antarctica. One, the cold temperatures and strong winds, along with the 24 hour period of darkness during the Antarctic winter, make it a very difficult place to work and collect geological data.
Our understanding of the geology of the Antarctic region is based on the theory of plate tectonics. Plate tectonics is the theory that the earth's crust is made up of a series of pieces. Each piece is called a plate. These plates float on top of the semi-fluid mantle like rafts.
The mantle is believed to have convection cells within it which move these plates around. Because of the theory of plate tectonics, most geologists believe that up until about million years ago, South America, Africa, India, Australia, and New Zealand were all joined together in one very large mass called Gondwana.
One piece of evidence that supports the idea of this large land mass is that all of these continents fit together like a jigsaw puzzle.
It has also been found that when these continents are placed together they share matching fossils, rock types, and land features. The best explanation for this similarity is that the rocks, fossils and land features formed when the continents were joined together. When Gondwana started to break up, the land masses gradually moved into the positions that we see them today.
This idea that all the land masses were formed together allows us to make some assumptions about the geology of Antarctica even though very little of the crust of Antarctica is exposed.
For example, if minerals found in the rocks that were formed before the break up of Gondwana are found in the mountains of South America, then we assume that we will find the same minerals in the mountains of Antarctica.
This is because we can assume that they were formed at the same time and with the same basic processes. Many people believe that Antarctica is a place of unlimited resource wealth. But the harsh climate, short work season, and thick ice make the recovery of these resources very difficult.
The economic value of a resource is determined by the current market value of the resource, the cost of moving the resource to where it is needed, and the cost of moving equipment and workers to recover the resource. The technology to remove and transport mineral resources has not yet been developed but as supplies worldwide are depleted, it will become more cost effective.
There are two opposing views about the feasibility of resource recovery in Antarctica. One side is that by the time it is feasible to use an Antarctica resource, alternative sources will exist. Instead of using petroleum for energy there will be development of fusion reactors, solar, or geothermal energy.
The other view is that increasing economic pressure will force mineral and petroleum exploration into more and more remote regions as resources are gradually depleted in other lands.
One of Antarctica's most important resources is ice. As a resource it has potential as a fresh water supply. Some people have considered towing icebergs from Antarctica to parts of the world in need of fresh water. At present the delivery costs make these ventures unprofitable.
Another possible use of the ice on Antarctica is as a long term deep freeze storage site for grain and other foods. Again the costs of shipping and handling are prohibitive. There are coal deposits found along the coast of Antarctica.
It is also very wide spread throughout the Transantarctic Mountains. These deposits were formed between 35 million and 55 million years ago when Antarctica was covered by ancient swamps. Coal forms in swamps as plants die and are buried before they can be completely decomposed. They are then covered by other sediments such as sand and mud.
This burial allows the hydrocarbons in the coal to be preserved for future generations to use. Coal is used as a source of direct heat and also to generate electricity in coal burning power plants.A Reading and Writing Approach to Teaching Environmental Geology Helen N.
