Geography is the study of natural and human constructed phenomena from a spatial perspective. Geography has two main sub disciplines:
Human geography includes such subjects as demography, human settlements, transportation, recreation and tourism, resources, religion, social traditions, human migration, agriculture, urban systems, and economic activities
Physical geography is concerned with the study of the Earth’s atmosphere, biosphere, hydrosphere, and lithosphere from theoretical and applied viewpoints.
Sometimes the disciplines of human and physical geography combine knowledge to create a more holistic synthesis.
The Don Juan Pond in western Antarctica is the most saline water body on Earth, at approximately twelve to thirteen times the salinity level of other typical seas of the world....
DenmarkLast Updated on 2014-12-19 12:32:19Denmark is a nation of just over five-and-a-half million people in Northern Europe, bordering the Baltic Sea and the North Sea, on a peninsula north of Germany (Jutland) and includes roughly 500 islands, including several major islands (Sjaelland, Fyn, and Bornholm). It is a part of the generally fertile and mostly agricultural region known as the North European Plain. This entire region is generally flat to slightly rolling and is overlain with glacial deposits.
Denmark also includes the Faroe Islands and Greenland.
Its major environmental issues include:
air pollution, principally from vehicle and power plant emissions;
nitrogen and phosphorus pollution of the North Sea;
drinking and surface water becoming polluted from animal wastes and pesticides
Flooding is a threat in some areas of the country (e.g., parts of Jutland, along the southern... More »
Canadian Rocky Mountain Parks, CanadaLast Updated on 2014-12-08 19:23:12The contiguous national parks of Banff, Jasper, Kootenay and Yoho, with the adjoining Mount Robson, Hamber and Mount Assiniboine provincial parks (50°34'-53°28'N, 115°10'-119°32'W), are World Heritage Sites located at the continental divide of the central Rocky Mountains at their highest point. They protect an approximate linear extent of 400 kilometres (km) of forested mountain landscape studded with dramatic peaks, glaciers, lakes, cascades, canyons and limestone caves,. The Burgess Shale fossil site, inscribed as a World Heritage site in 1980 and noted for its fossil remains of soft-bodied marine fauna, is within Yoho National Park.
The parks are a 400 km long continuous belt of protected areas bestriding the central Rocky Mountains at their highest, along the British Columbia-Alberta border. The ridge axis extends from north to south: Jasper... More »
BiogeographyLast Updated on 2014-11-30 22:10:52Biogeography is the study of the spatial distribution of biological organisms. The scale of analysis ranges from very small micro-topography regimes to continental dimensions. Fundamental concepts in this field of study are the nature of barrier formation and response of species in their patterns of travel and migration; in particular, the presence of rivers, mountain ranges, deserts and other natural boundaries are examples of large scale barriers. Besides such major landform barriers, there are soil, topographic and meteorological factors that influence the distribution of each species. In the case of smaller scale regimes that are applicable for some bacteria or limited range plant species, there are often very restricted niches; for example, certain bacteria extremophiles may be limited to such localized features as small geyser pools, and some rare plants may have a single extant...

Energy profile of CanadaLast Updated on 2014-11-30 21:44:07 Canada is one of the world's five largest energy producers and is the principal source of U.S. energy imports.
Canada is a net exporter of most energy commodities and is an especially significant producer of conventional and unconventional oil, natural gas, and hydroelectricity. It stands out as the largest foreign supplier of energy to the United States, its southern neighbor and one of the world's largest consumers of energy. Just as the United States depends on Canada for much of its energy needs, so is Canada profoundly dependent on the United States as an export market. However, economic and political considerations are leading Canada to consider ways to diversify its trading partners, especially by expanding ties with emerging markets in Asia.
Canada's large territory is endowed with an exceptionally rich and varied set of natural resources, which enables it to... More »
Mississippi RiverLast Updated on 2014-11-29 22:15:22The Mississippi River drains the largest river basin in North America, and is one of the major rivers of the world.
The Mississippi River watershed is the fourth largest in the world, extending from the Allegheny Mountains in the east to the Rocky Mountains in the west. The watershed includes all or parts of 31 states and two Canadian provences. The watershed measures approximately 1.2 million square miles (3.1 million square kilometers), covering about 40% of the lower 48 states. The Mississippi drains most of the United States between the Appalachian Mountains in the east and the Rocky Mountains in the West.
The mainstream of the Mississippi River has headwaters rising at Lake Itasca, Minnesota and flows approximately 2340 miles (3765 km). Though the longest part of the river includes the the Missouri River which flows approximately 2540 miles (4088 km) before joining the... More »
