1912‚ Alfred Wegener proposed the past existence of a supercontinent called Pangaea (or Pangea). According to Wegener‚ Pangaea had split apart into a northern half called “Laurasia” and a southern half called “Gondwanaland”. Surrounded by a global ocean called “Panthalassa” and separated by a big body of water called “Tethys Sea”. The slow drifting of continents has been occurring over the past 250 million years. In the 1960s‚ the theory of plate tectonics began to take credence because of the modification

Climate Change Impacts on the Ocean Climate change has widespread effects. It doesn’t just affect weather and temperature. It will also have lasting effects on the ocean and the ecosystems within it. Coral reefs get hit hard by the temperature of the water getting warmer. “Warming of as little as 1°C causes coral bleaching‚ a state in which the tissues of the coral become colorless because of the loss of the zooxanthellae”(Hoegh-Guldberg‚Donner‚pg. 9‚ par 3). This bleaching can stress the reefs

Lab 2B 1. In the Figure 1 schematic view of the ocean bottom‚ the vertical scale is given in kilometers (km). This vertical scale is vastly different from the horizontal scale. The vertical distance between scale markings is [(1)(10)(100)] km. 2. The ocean trench in the schematic view has a maximum depth of [(8)(80)(800)] km below sea level. 3. The distance between scale markings on the horizontal scale is 100 km. Comparison of the vertical and horizontal scales indicates that the vertical scale

climate change‚ our oceans are devolving into waters dominated by microbes‚ jellyfish‚ and disease. By destroying the marine habitats within our seas and oceans‚ humans are threatening their own livelihood by not only destroying a food supply but also other benefits that marine life offers. Pollutants such as‚ everyday trash‚ chemicals‚ and farm fertilizers are not only killing off marine life‚ but also destroying natural habitats within those waters. The pollutants in our oceans and seas are not only

Your Name: Professor’s Name: Course Number: Date of Submission: Deep Ocean Mining Part 2 Deep ocean mining is an alternative to land mining in search of minerals such as copper‚ gold‚ manganese or cobalt among other minerals. The minerals on land are being depleted owing to the increasing demand for these minerals‚ and this makes the deep sea bed an alternative to the exploitation of minerals. The fact that the water

Sakashita‚ Oceans program director at the Center for Biological Diversity. She is an authority in the field of hydrosphere research and hence her views carry some weight. This article was published in the huffington post which is a newspaper for the masses. This article touches on the threatening environmental issue of ocean acidification through carbon dioxide pollution and its purpose was to act as a plea to enlighten the general population to lower carbon emissions to reduce ocean acidification

consumption of goods increases and therefore the demand for plastic. The latter results in a greater pollution consist of 75 percent of plastic. The amounts of plastic waste end up largely in rivers that flow again to oceans and seas. The quantity of plastic that finally floats in oceans is called the plastic soup. In order to maintain a responsible ecosystem‚ we should decrease the plastic soup. The question is‚ how can this objective be achieved. First of all‚ it is necessary to amplify why this

smuggling to Australia is one of the most crucial issues faced by Australia through the Indian Ocean Region‚ especially in north-west part of Australia. Through 2009 and 2010‚ there has been a marked increase in the numbers of asylum seekers trying to enter Australia by sea‚ mostly across the Timor Sea and the northwest Indian Ocean. IUU fishing is a serious problem faced by Australia in the Indian Ocean‚ including off the Australia’s northwest coast. Increased world demand and the limitation of fish
