Why Did Pangea Really Exist?

In 1596- Abraham Ortelius took note that the coastlines of the continents seemed to be too fitting together. He initiated a theory that stated that the continents were probably joined at one point in time and were torn apart between Europe and Africa. In the year of 1912, Alfred Wegener stated that the continents were once joined in a supercontinent called Pangea.

One evidence of this theory is molten material. Molten Material is magma erupting from mid-ocean ridges. Alvin the submarine found weird rocks shaped like pillows or toothpaste. This tells us this magma cools quickly underwater. Another type of evidence are magnetic stripes. Magnetic stripes are patterns in the ocean floor to prove Earth’s magnetic field has reversed itself in history. Scientist also looked at the “magnetic memory” of the rocks. Scientist drilled pipes through water to drill holes into the ocean floor. Scientists discovered that the older rocks were further away and younger rocks were closer. Those were the three types of evidence that scientist used to support the theory of Sea Floor Spreading.

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 theory of plate tectonics was first developed by Alfred Wegener. He concluded that the continents seem to have a similar shape and could potentially fit together. This suggested that they were at one time joined together as part of 2 super continents called Gondwanaland and Laurasia was in the north. This theory was said to be proven by the discovery of fossilised remains of a mesosaurus that were found on the coasts of Brazil and Gabon. Sea floor spreading is another theory that supports the idea of plate tectonics; this theory discovered that rock is being formed under the ocean as a new sea floor. Sea floor spreading was shown in the Atlantic, where it is believed the Eurasian and North American plates are moving apart on a

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.

About 225 million years ago, according to the theory of “Pangaea,” the world was once a single supercontinent that contained all the dry land. Approximately 10 million years ago, North America was shaped by the majestic Canadian Shield. About 2 million years ago, in North America, the grand glaciers laid the land of Canada and the United States, southbound as far as from Pennsylvania all the way to the Pacific Northwest. Recently, about 135 million to 25 million years ago, four massive ranges—the Rockies, the Sierra Nevada, the Cascades, and the Coast Ranges, arose in western North America. About 35000 years ago, the ancestors of the Native Americans, the nomadic Asian hunters, first

Between 280 million and 225 million years ago, the earth’s previously separated land areas became welded into a landmass called Pangaea. About 120 million years ago, due to the continental drift, this landmass began to separate. It split the old world and the new world apart, which dividing North and South America from Eurasia and Africa. The separation lasted for million years that it fostered divergent evolution. The new world and the old world’s biological evolution followed individual paths, becoming two separate biological worlds. However, after 1492, human voyagers reversed this tendency. In October 1492, Christopher Columbus and his crew landed in Bahamas. After Columbus arrived in

Millions of years ago according to scientist the whole world was one large mass called Pangea. When this mass began to split, it divided the Americas from the Eastern World along with the people on it. This resulted in tens of thousands years apart from one another which led to different developments on each continent. After all these years though a man named Columbus’s discovers the Americas in 1492. As soon as he took

James Hutton was the first scientist to address the Earth was millions of years old, as well as alive and is continuously being formed. Charles Lyell popularized uniformitarianism, and believed the Earth was being shaped by slow moving forces. Alfred Wegener introduced the foundation for the theory of continental drift. Wegener was one of the first to recognize and have an understanding of how the Earth works which required data and information from earth sciences. In the 1960s, the theory for the continental drift became known as the theory of plate tectonics or plate building.

About 200 million years ago there was one big continent called Pangaea. They believed that, this landmass began to separate. They believed that the Atlantic Ocean formed, dividing Africa and Eurasia from the Americas. Over the next several million years plants and animals changed and made to separate biological worlds. It wasn’t until Christopher Columbus and his crew sailed to the Americas in October 1492, they started interacting with each other.

Who proposed that all of the present continents were once joined together in a single supercontinent called Pangaea?

The theory of Pangaea suggests that the continents were once stuck together into one huge continent. Eventually they started drifting into separated landmasses, which gave birth to the modern continents.

Because of Pangia humans ended upon 2 continents, Pangia was 1 big super continent. Why they went here is because their food was on those two continents. The original humans food was on Africa and Asia while tetonic plates were moving faster.

Alfred Wegener was a meteorologist and astronomer. He was the first scientist to introduce the theory of the continental drift. Wegener theorized that at one time the continents were one large landmass or Pangaea that had drifted apart. His ideas were initially rejected by other scientists. It was not until long after Wegener’s death that proof was obtained and his theory verified.

In the middle of the eighteenth century, James Hutton proposed a theory, uniformitarianism; “the present is the key to the past”. It held that processes such as geologic forces- gradual and catastrophic-occurring in the present were the same that operated in the past. (Matt Rosenberg, 2004) This theory coincides with the theory of Continental Drift that was first proposed by Abraham Ortelius in December 1596, who suggested that North, South America, Africa and Eurasia were once connected but had been torn apart by earthquakes and floods. He also discovered that the coasts of the eastern part of South America and the
