  1. What is Marine Science?<\/strong><\/li>\n<\/ol>\n

    It is the study of organisms of the sea.<\/p>\n

      \n
    1. Why do we need to study Marine Biology?<\/strong><\/li>\n<\/ol>\n

      71% of our Earth is the ocean. Our life probably originated in the sea, and marine life helps determine the very nature of our planet. Through the study of marine biology, we can have a better understanding of the relationship between aquatic animals and the environment. How do they influence each other? How do these marine animals that we share on a planet live in the ocean? We could learn a lot from marine life and create a better world.<\/p>\n

        \n
      1. Discuss the importance of ocean explorations and give an example of an<\/li>\n<\/ol>\n

        expedition and its discovery or contribution to studying oceans today.<\/p>\n

        The ocean’s contributions to the world are significant. Oceans can regulate the climate, produce oxygen for living organisms, provide food for both marine animals and humans, help people to transport, and offer resources for us such as submarine oil… The world can\u2019t live without the oceans. There are a lot of things in the ocean that we haven\u2019t discovered yet. Besides, we are using ocean resources, so we have to know whether it\u2019s sustainable to keep exploiting the ocean resources. Therefore, it is crucial to learn ocean, to be aware of the limit of oceans, and more importantly, we need to make efforts to protect the oceans. A lot of people in history contribute to the study of oceans. James cook, for example, was one of the first ocean explorers. He created the first dependable charts and brought back plant and animal specimens. He also found that eating citrus (containing vitamin C) could prevent scurvy. Therefore, he proved that through careful observation, scientific discoveries can be made by nonscientists.<\/p>\n

          Submersible (AUVs & ROVs)- helps to explore inhospitable environments such as the deep sea<\/p>\n

          Crittercam- can take photos for scientists to study animals\u2019 behavior<\/p>\n

          1. What are the layers of the Earth?<\/li>\n<\/ol>\n
              \n
            • Crust<\/li>\n
            • Mantle<\/li>\n<\/ul>\n

              Upper mantle<\/p>\n

              Lower mantle<\/p>\n

                1. Differentiate the oceanic crust from the continental crust.<\/strong><\/li>\n<\/ol>\n
                    \n
                  • Different composition:<\/li>\n<\/ul>\n

                    Oceanic crust- basalt \u00a0\u00a0\u00a0Continental crust- granite<\/p>\n

                      \n
                    • Different density:<\/li>\n<\/ul>\n

                      Oceanic crust- 2.9 g\/cm3 \u00a0\u00a0\u00a0\u00a0Continental crust -2.7g\/cm3<\/p>\n

                      Different location:<\/p>\n

                        \n
                      • Oceanic crust- mid-ocean ridges<\/li>\n<\/ul>\n

                        Continental crust- the outermost layer of Earth\u2019s lithosphere<\/p>\n

                          \n
                        1. Explain the Theory of Continental Drift.<\/strong><\/li>\n<\/ol>\n

                          Alfred Wegener was the one who proposed this idea. He pointed out that the continents had drifted. Matching mountain ranges across oceans, glacial ages, climate evidence and fossil distributions such as Mesosaurus were all his evidence to support his idea. However, some scientists objected to his idea because it was too far-fetched and contrary to the laws of physics.<\/p>\n

                          1. What is the evidence of seafloor spreading?<\/strong><\/li>\n<\/ol>\n
                              \n
                            • Earth\u2019s magnetic field<\/li>\n
                            • Age of the sea floor (younger sea floor is near the mid-ocean ridge. Sea floor\u2019s age is growing with increasing distance from the mid-ocean ridge)<\/li>\n
                            • The pattern of worldwide earthquakes<\/li>\n<\/ul>\n

                                  Two plates move toward each other<\/p>\n

                                    \n
                                  • Convergent<\/li>\n<\/ul>\n

                                    Two plates are moving separated<\/p>\n

                                      \n

                                      1. Describe asthenosphere, mid-ocean ridge, and trench.<\/strong><\/li>\n<\/ol>\n
                                          \n
                                        • The asthenosphere is a layer beneath the lithosphere with the partially-molten mantle.<\/li>\n
                                        • Mid-ocean ridge<\/li>\n<\/ul>\n

                                          When two continents are separated, some regions rise, like a mountain. Volcanoes and earthquakes occur along with this active rift area.<\/p>\n

                                          • Trench<\/li>\n<\/ul>\n

                                            The trench is like a gap or crack in the ocean. It is the deepest part of the ocean.<\/p>\n
