In the article, “Is Zealandia a Continent?” by, Thomas Sumner, it explains how and why a new continent came to be. This article was published on March 13, 2017. Throughout this article it shows that continents are not always what they seem. For instance, in the article it says that originally they thought that New Zealand, and surrounding land masses were just islands. But, it turns out that they were just the part of the Zealandia continent that was above water. This article also explains that if Zealandia was once a continent, than it further proves the supercontinent hypothesis. If it was part of the supercontinent, than throughout the 100 million years of continental drift, some of Zealandia submerged under water. Scientists have recently
Over the centuries, the making of the Big Island as we know it today eventually entailed the growth and conjoining of six separate volcanoes, building all the way up from the seafloor, some 18,000 feet below the ocean’s surface. These volcanoes, from northwest to southeast, are named Mahukona, Kohala, Mauna Kea, Hualalai, Mauna Loa and Kilauea, and become younger as one moves north to south. Mahukona Volcano, just off the Big Island’s northwest coast, was the first volcano to start forming. Now submerged beneath the surface of the ocean because it is sinking into the Earth’s crust under its own vast weight, Mahukona is no longer visible. As the Pacific Plate slowly continued moving northwestward over the hotspot, the location of the rising magma moved relatively southeastward, and through time the rest of the Big Island volcanoes formed along that path.After Mahukona, Kohala Volcano, the precursor to today’s Kohala Mountain, erupted next. As Kohala Volcano emerged from the sea and joined with Mahukona, a much larger Big
Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...
Federation is the joining of states to become one nation. The Australian government first considered federation in 1890 when premier Henry Parkes convinced other premiers to discuss federation in the Australasian Federation Convention. Australia finally federated in 1901 after many failed attempts at doing so. Australia finally federated because
Ocean floor subduction was ongoing and as Avolonia continued to move north, the Iapetus Ocean closed and Avolonia crashed into Laurentia and Baltica. Due to this subduction and closing of the Iapetus, Ireland became one. England and wales also joined with Scotland. But the story isn’t over just yet, although wales and England were now joined with Scotland, they still had some distance to go until they reached their present day location.
Pangaea or Pangea is the name given to the supercontinent that existed during the Paleozoic and Mesozoic eras, before the process of plate tectonics separated each of the component continents into their current configuration. The movement of Earth’s tectonic plates formed Pangaea and ultimately broke it apart.
The theory of plate tectonics, only recently introduced to the world, transforms the thought that the earth has been the same since its beginning. The theory alters the view of the average person almost in the way that Columbus showed the world was round. The theory of plate tectonics was developed from the theories of continental drift and sea-floor spreading and states that the earth’s surface is divided into several large plates, which are constantly in motion.
Since the beginning of human kind there has been a cloud of wonder of how our planet was formed. Scientist interested in this field through out the years have developed many different theories to how our planet came about. Before the Twentieth Century, scientists and geologists thought that mountain structures were due to the massive tightening of the earth caused by the gradual cooling of molten rocks. In 1900, American scientist Joseph Le Conte, published an article in the Appleton's Popular Scientific Monthly. He described that the problem in understanding mountain building was establishing the cause of sideways pressure. It was not until 1910, that an American Geologist named F.B.Taylor, proposed the idea of a continental drift. Other scientists dismissed Taylor's idea, because there was just not enough proof. However, Taylor's idea was then backed up by a German scientist named Alfred Wegener. He proposed that the continents surrounding the Atlantic Ocean, Africa and South America fit together like a jigsaw puzzle. His broad range of studies enabled him to incorporate his theory of Plate Tectonics. Wegener, later in 1915 while in the German military published his idea that interpreted how his continental drift theory worked. He proposed that a huge landmass called Pangea, meaning ("all land") existed 200 million years ago. He furthered explained that this super continent began to drift apart very slowly throughout millions of years into what it looks like now. Wegener went on several expeditions through out his life to the continents of South America and Africa.
About 20 million years ago the last part of the Farallon sea floor plate subducted under the North American plate. This put the North American plate and the Pacific plate into contact, but unlike the Farallon sea floor plate, the Pacific plate sheared against the side of the North American plate. Because there was no plate subducting, the North American plate was in direct contact with the mantle (Tierney, 29). Heat from the mantle made the continental crust more ductile, which allowed the crust to extend and thin.
In the movie Walkabout it take place most of the time in the Australian outback. The outback is depicted as a desert, extremely hot, flat for miles and then hilly for a little bit, but there are still signs of life. There are three main characters in this movie, a brother, sister, and an aboriginal man. The movie the Tempest takes place on the Island of Prospera the island is dark, gloomy and dry there is some life there but not much. This movie also has three main characters, Prospero and her daughter who got banished to the island, and Caliban a man who has always lived on the island. In this paper I will be comparing and contrasting the outback in Walkabout with the Island
Gondwana was built of almost all of the landmass, nowadays found in southern hemisphere containing Africa, Australia, Antarctica, South America, Madagascar, Arabian Peninsula and India subcontinent. The later two landmasses mentioned have moved into the northern hemisphere. Furthermore, Florida and most of Central America, southern Europe and much of south-central and southeastern Asia all were parts of Gondwana at different times (Cocks, et al., 2013). North China, South China, Tarim and Annamia might also have been primary parts of Gondwana during the latest Precambrian. Even the large continents of Baltica and Siberia were very close to the superterrane in Late Neoproterozoic and Early Palaeozoic times (Cocks, et al., 2013).
Beneath the waves of the south pacific, lays a land mass known to scientist as Zealandia, the land of which makes up New Zealand and New Caledonia. Zealandia spans 5 million square kilometers and is very vast. Zealandia broke off from the super continent Gondawana about 100 million years ago and has been hidden under the ocean for years. Only about six percent of zealandia shows to the world and that is known as New Zealand and New Caledonia. So why is Zealandia not considered a continent if it is so big? Well because Zealandia is underwater, as I previously said there is only six percent of the total mass showing to the world. “If you could pull the plug on the world’s oceans, then Zealandia would probably long ago have been recognized as
Ever since the beginning on time, Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth, and possibly of what the Earth may become at a certain point in time, has a great influence on understanding all aspects of living things, either in the past, present, or future. The Theory of Plate tectonics is accredited to most of the creations of Mountain Ranges, the Centennial drifting Theory, for earthquakes, and volcanic activity. Plate tectonics and mountains also play a big part in the Earth and its geological features.
The history of New Zealand begins between 800 A.D. and 1300 A.D., when the Māori people arrived from Polynesia to the mountainous island they called “Aotearoa.” The people “lived in tribal groups” fairly peacefully (Wilson). However, life began to change for the Māori people when they first came into contact with a European in 1642, when Dutch explorer Abel Tasman “discovered” the island. In 1769, “[James] Cook successfully circumnavigated and mapped the country” (History). These explorations marked the beginning of Europeanization for the young country of New Zealand. Whalers and traders soon arrived, and missionaries arrived in 1814. When the Māori met with Europeans, events followed a similar path to the colonization of America and the decimation of the native populations-- “contribution of guns…, along with European diseases, led to a steep decline in the [population of] Māori people.” (History). Consequentially, “their chieftains entered into a compact with Britain, the Treaty of Waitangi, in which they ceded sovereignty to Queen Victoria while retaining territorial rights,” in...

Continental drift is the theory of the shifting of the positioning and look of continents in the past and their predicted look in the future. 2.5 cm a year doesn’t seem like a lot unless we calculate it in the millions or hundreds of million years, possibly even 200 million years ago, the era of Pangea. Pangea is the theory that all the 7 continents that we have classified today were joined into one supercontinent, Pangea. The main evidence for this theory of continental drift and Pangea is that almost identical animal and plant fossils, and similar rock formations, are found on different continents. The coastlines of continents even match up with a little bit of rotation and alignment. Through the years, parts of the supercontinent started to drift apart and continued drifting to turn into the continents we know
