Ocean current

1. Outline Alfred Wegener’s hypothesis of Continental Drift Alfred Wegener believed all Earth’s continents were once joined together but gradually moved apart for millions of years by cracking and dividing due to slow currents of magna beneath it. 2. Cut out the attached Gondwana Jigsaw along the dotted lines. Fit the continents together and glue them in position. Hint, refer to other sheets for map. 3. Describe the evidence for Continental drift. All the continents fit together much like…

Ocean acidification is described by many scientists as a consequence of rapid increase of carbon dioxide absorbed into the ocean. As ocean acidity increases, its capacity to absorb CO2 from the atmosphere decreases. This decreases the ocean 's role in moderating climate change, "they write (Cullinane.1). As serious as this may seem several damaging effects are happening to the oceans as we speak. The most important creatures in the ocean’s ecosystem like coral are being depleted and…

Oil spills kill thousands of birds and fish. The integrity of the ocean water is depleted. Not only do oil spills affect marine ecosystems, but seismic testing is harmful to any marine mammal dependent on sound. Seismic testing shoots sound waves that can go through ocean depths and 500…

but not significant enough to make a conclusion of temperature and rainfall directly affecting the distribution of Ctenophora. If currents change because of an increase or decrease in rainfall or temperature, then…

Because the climate change might greatly influence the ecosystem, their cultures (social impacts), and economy. First, the climate change will greatly interrupt the ecosystem in the Arctic region, because of the permafrost. Including warmer ocean currents that was caused by climate change. When the active layer is decomposed and reaching too much, because of the methane(stronger than green gas) was produced by climate change. Then the lose of permafrost case bodies of water was going to sink…

The Nature Conservancy’s video “Help Kelly Slater Save Our Oceans” has a deeper meaning that you may not see just from watching the video and not understanding what Kelly is trying to Portray. But if you can overcome this hurdle and grasp the true meaning behind what he says and how he views the ocean as this serene and tranquil place of beauty. You’ll be able to see the ocean as Kelly does in the video. So by understanding the meaning and message behind the video you can see just how well the…

The ocean is the most obvious feature of the earth 's surface. About seventy percent of the earth’s surface is covered by water. Beneath this water are the familiar sands of the beaches we visit during the summer months, however further offshore this water covers an amazing submarine landscape of underwater trenches, mountains, and plains. This differs from the continents, mainly because they are physically separated from one another, whereas the oceans are continuously interconnected. The…

plastic trash, aluminum cans, and other forms of litter on beaches, which tides can pull in with its currents. Fishes can mistaken trash for food and ingest them, which can either kill them or negatively…

preserve the world. Amitai Etzioni discussed how the government should be more concerned about the ocean because it impacts the climate. Government funding should be put towards oceanic studies because people receive a lot of their food supply from the ocean. Finally, Etzioni discussed the amount of energy that could come from harnessing ocean currents. Etzioni has a great argument as to why ocean exploration should come before space exploration, but his examples barely support his argument. I…

life in the ocean. The marine biome covers more than ¾ of the planet we call home. It provides more than ½ of the world’s oxygen and locks away our CO2. Without it more than 3.5 billion people would starve and the US would lose $574 billion of its gross domestic product. The first organisms on Earth came from the ocean, but our marine biome is dying. The average temperature of the world has increased 1-2 degrees over the last few decades. Coral reefs are being bleached and dying from ocean…
