16. What was Pangea? How does the theory of Plate Tectonics lead modern scientists to believe that the Earth will experience a second Pangea (in ~250ma)?…
Over the years proceeding the birth of the theory, increasingly convincing evidence has been gathered for proof of the theory of plate tectonics. In 1912, Alfred Wegner proposed the theory that continents are sat upon tectonic plates and that these plates are slowly drifting around the Earth (continental drift). Since then, volcanic and seismic events have made up a large proportion of the evidence towards the theory, including volcanic eruptions at both constructive and destructive boundaries, hotspots, sea floor spreading, paleomagnetism, and seismic earthquakes. However, not all of the evidence supporting plate tectonics comes from volcanic and seismic events; other evidence includes continental fit, geological evidence, biological evidence, climatological evidence and other activity at destructive plate margins.…
Pangaea: The primeval supercontinent, hypothesized by Alfred Wegner, that broke apart and formed the continents and oceans as we know them today; consisted of two parts- a northern Laurasia and a southern Gondwana.…
One evidence is the continental drift that made Pangea drift into the us known continents today. The next evidence is sea floor spreading which is demonstrated by alternately magnetized volcanic crustal rock. New crustal material was formed by volcanic eruptions by the crest of mid oceanic ridges and therefore slow lateral movement of the crust away from the ridges was occurring.…
A. He proposed a hypothesis that would account for the close “fit” of the shapes of the facing continents. His continental drift hypothesis required a preexisting super continent, Pangaea, which split into the continents of the world.…
-The relationship between continental drift and the formation of the Earth’s Oceans stems from plate movement that occurred on Earth. There is a theory that all the continents were once all one big piece of land named Pangaea, and over millions and millions of years the land of Pangaea started to split apart into many different continents. It divided Panthalassa, the large global ocean that surrounded the supercontinent Pangaea, into many different oceans instead of just one big one and now we have many various oceans around the world.…

The plate tectonics theory was made by a German named Alfred Wegener. He stated that a single continent existed about 300 million years ago named Pangaea and that it split into two continents of Laurasia in the north and Gondwanaland in the south. Today’s continents were formed by further splitting of the two masses.…
The Continental drift was the process in which the Earth’s land surfaces ( at the time known as the pangea) started slowly breaking apart and drifting away. This has continued until the continents were in the places we know them to be today. This drift has caused the formation of separate oceans instead of one huge one. This drift still continues today.…
2.The theory of “Pangaea” exists suggesting that the continents were once nestled together into one mega-continent. The continents then spread out as drifting islands.…
The plate tectonics theory was put forward by Alfred Wegener suggesting that the continents were at one point all conjoined in one supercontinent known as Pangaea. He then said that Pangaea had drifted apart through the movement of plates to give us the current places of continents we have today. Wegener's theory was linked to a variety of evidence, however it took further research and evidence for this to become a leading theory. This means that although volcanic and seismic events help to prove the plate tectonics theory valid, there is also a range of other factors involved.…
They discovered how the temperatures warmed and cooled several times. Scientists also believe that this ice age theory may also have to do with the continental drift. They believed that the ice movement, that occurred 2.1-2.4 million years ago, may have caused the continents to separate apart from each other and still to this day they believe that the continents might still be moving.…
The Great Ice Age contributed to the origins of the continent’s human history. Debatable evidence has indicated that some of the early people may have reached America by makeshift boat, or arrived through travelling by foot. For these early humans to travel by foot, the continents once had to be connected. The Pangaea theory is the imaginary landmass that existed when all the continent were joined about 300-200 million years ago. The main connection between the continents was the Bering Strait. The Bering Strait, also known as the ‘Land Bridge’, connects Eurasia with North America in the area of present day Bering Sea between Siberia an Alaska. This Land Bridge was the way hunting would be carried out and eventually, the separation of people to develop their own civilizations.…
