In 1915 the first edition of The Origin of Continents and Oceans‚ a book outlining the Continental Drift theory of Alfred Lothar Wegener‚ a German meteorologist‚ was published; expanded editions were published in 1920‚ 1922‚ and 1929. About 300 million years ago‚ claimed Wegener‚ the continents had formed a single mass‚ called Pangaea (from the Greek for "all the Earth"). Pangaea had split‚ and its pieces had been moving away from each other ever since. Wegener was not the first to suggest that the

as commercial entrepots‚ a void fell over trade in the Indian Ocean that would persist until 750 AD‚ which signaled the beginning of Muslim dominance in the area. Initially confined to the Persian Gulf‚ Muslims began to expand their circle of influence to the eastern coast of Africa. Like Meroe and Aksum‚ the eastern coast of Africa provided a pipeline to the interior luxuries of the continent‚ as well as to those of the Indian Ocean. However‚ unlike Meroe and Aksum‚ the sheer length of the coast

Premium Blue Ocean Strategy
Blue ocean strategy generally refers to the creation by a company of a new‚ uncontested market space that makes competitors irrelevant and that creates new consumer value often while decreasing costs. The following guidelines may be proposed to companies seeking to create blue oceans: 1. Identify the key features/ dimensions that currently define a product/ service.2. Identify a group of customers who only value a subset of these features. These customers may be currently using lower end alternatives

overuse our ocean resources? It is possible to overuse our ocean resources. We can drill and use an excessive amount of oil from the bottom of the ocean. This resource is made up of dead fish and other creatures that sink to the ocean floor and as sediment builds up the dead animal remains decompose and heat up to form the oil and natural gas. This can take up to thousands of years to form and if humans use too much oil we will have to wait another thousand years to use the oil the ocean provides us

The ocean appears to be a large trash can for disposing waste in the convenience for humans. According to UNESCO‚ statistics show that in 2006‚ 46‚000 plastic materials were found scattered every square mile in the ocean; in addition to that statistic‚ millions of marine animals are severely injured or even fatal

Keeping oceans young and productive: - Upwelling and Downwelling Oceans cover two thirds of our planet thus they can be regarded as one of the major factors in shaping this blue marble in space. But oceans just don’t result in varying gradient of humidity that gives rise to different vegetations and ultimately widely different biomes when coupled with other factors such as differential exposure to solar radiation‚ and inherent soil type. Oceans are living systems that themselves support numerous

organisms die a year because of the ocean temperatures rising? One reason the ocean temperature surges is because of the greenhouse gas. As greenhouse gas (a gas from the greenhouse effect that benefits by absorbing carbon dioxide‚ chlorofluorocarbons‚ and infrared radiation; different kinds of elements and gases) collects together and increases‚ it traps more heat energy into the Earth‚ and making the temperature rise. Another way this is caused is when the warmer ocean water makes movement‚ it changes

Actually‚ there is not any mixing of these two oceans‚ but there is a mixing of the "glacial melt fresh water"(Light blue color) with the "saline sea waters" (Dark blue color). However‚ due to density contrast‚ they don’t mix... at least not immediately! It has been stated that this stange and natural phenomenon is caused by and where heavy‚ sediment-laden water from the Alaskan glacial valleys and rivers pour into the open ocean. There is
