What Are The Continents Coastlines Once Connected

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.

The first, would be Land features. Alfred Wegener saw how the coal fields in North America and Europe lined up, he also realized that mountain ranges in North America and Africa lined up. The second, evidence he used were the fossils. There were three types of fossils he found the first was the glossopteris a fern like plant found in Africa, South America, Australia, India, and Antarctica. The second and third were the Mesosaurus and the Lystrosaurus fossils, they were freshwater reptile fossils on continents separated by oceans. The third evidence Alfred Wegener used was, the climate zones. Alfred Wegener looked at the past of the climates and he found scratches in rocks from glaciers in South Africa. Those were the three main evidences Alfred Wegener used to prove Continental Drift

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.

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.

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

According to the theory of “Pangaea,” the world was once a single mega-continent that contained all the dry land about 225 million years ago. North America was shaped by the majestic Canadian Shield about 10 million years ago.

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

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?

At one point in time there was one big super continent known as Pangea. There was no need to reconnect with the other continents because they were already connected, it was just a matter of how long it would take to get from one place to another. Shortly after, continental drift happened where Pangea split into several continents. One of them is now known as Europe; another is America. 1492, the year that changed everyone’s mindset about what happens if someone should go overseas, Christopher Columbus didn’t fall of the earth like projected. However, he did find America; which led to the Columbian Exchange. The Columbian Exchange, also known as the great exchange, was the act of the new world (America) and the old world (Europe) trading

Back about 21,00 years ago there was one big continent called Pangia. Then plates started moving, the ice age happened, Land bridge formed then disapered.

Geologists believe that between 280 million and 225 million years ago, the earth’s previously separate land areas became welded into a landmass called Pangaea. About 120 million years ago, they believe, this landmass began to separate. As this happened, the Atlantic Ocean formed, dividing the Americas from Africa and Eurasia. Over the course of the next several million years in both the Americas and in Afro-Eurasia, biological evolution followed individual paths, creating two primarily separate biological worlds. However, when Christopher Columbus and his crew made land in the Bahamas in October 1492, these two long-separated worlds were reunited. Columbus’ voyage, along with the many voyages that followed, disrupted much of the biological segregation brought about by continental drift.

2. What was the first line of evidence that led early investigators to suspect that the continents were once connected?

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
