Connecting Two Continents: The Ultimate Engineering Challenge Artist's rendering of concept for the Bering Strait bridge. The Bering Strait was last crossed by humans 20,000 years ago during the ice age, when ice formed a bridge between North America and Asia. Today, 47 miles and some of the harshest ocean and arctic conditions separate the two continents. However, there are many who believe there would be great economical, sociological, and political value in connecting the two land masses by bridge or tunnel.

- Other large continental masses, including the core cratons of North America (the Canadian Shield or Laurentia), Europe (Baltica), and Siberia, were added over time to form the supercontinent Pangaea by Permian time. When Pangaea broke up (mostly during the Jurassic), two large masses, Gondwana and Laurasia, were formed.

The Bering Strait and The Land Bridge However, it is clear that people and animals could have freely crossed the land bridge until after 11,000 years B.P. Elias can describe the paleoenvironment of the land bridge because of research he and his colleagues have done on pollen and the remains of insects and plants.

Pangaea, Gondwanaland, Laurasia and Tethys The world geography was not dominated by Pangaea for all time before the end of the Paleozoic. The Earth's plates had probably clumped up more than once in he past and moved apart before clumping up again. That cycle of clumping and reopening of oceans is called the Wilson Cycle.

The Paleozoic Era Before Pangaea there were older continents. At the beginning of the Paleozoic the continents were massed in another supercontinent called Pannotia. This was at the end of a global ice age.

Ice Age and Beringia The oceans became so low that some of the islands and continents we are used to seeing were actually connected by land! When we learn about the Ice Age, we will learn that people crossed a land bridge that once connected Asia and North America (a land bridge we now call Beringia). We will also learn that people traveled throughout North America and began to start tribes in different climates.

Surface of the Earth The plates move about one inch per year, so millions of years ago the continents and the oceans were in different positions. About 250 million years ago, most of the land was connected together, and over time has separated into seven continents. Last modified September 6, 2002 by Lisa Gardiner.

- The two continents that were connected by that stupid land bridge that I have no<br /><br />Idea what it is called but I really don't care I believe the two continents that were<br /><br />connected were North America and Europe.

- Pangea started to break up into smaller supercontinents, called Laurasia and Gondwanaland, during the Jurassic Period. By the end of the Cretaceous period, the continents were separating into land masses that look like our modern-day continents.An Austrian geologist stated that there had been once a land bridge connecting South America, Africa, India, Australia, and Antarctica.e named this land mass Gondwanaland. For how Pangea looked, it is better shown through a picture, than through words. So, what is happening now with the continents. As we speak, the continents are moving, they are always moving, how they move so slowly that you cant tell.

- If they do, there is nothing left but to conclude that the pieces were in fact joined in this way. Wegener began by demolishing the theory that large land bridges had once connected the continents and had since sunk into the sea as part of a general cooling and contraction of the Earth.iven the difference in density between continents and sea floor, plus the process of isostasy, Wegener reasoned that if continent-size land bridges had existed and somehow been forced to the ocean bottom, they would have bobbed-up again when the force was released.

How Did Continents Split? Geology Study Shows New Picture Over time, these islands collided with the large group of continents and were attached to it in a process called accretion. About 525 million years ago, that land mass broke apart, with North America on one side and South America, Africa and the small island pieces on the other. The two plates drifted apart, forming the Iapetus Ocean.

- The theory of Pangea is that millions of years ago all the continents were joined together in one enormous land mass known as Pangea. Then for a reason that is still not known for sure, the continents broke apart and began to drift in opposite directions.

Beringia The Bering land bridge is a postulated route of human migration to the Americas from Asia about 20,000 years ago. An open corridor through the ice-covered North American Arctic was too barren to support human migrations before around 12,600 years ago.

Beringia The latest emergence of the land bridge was 70,000 years ago. However, from 24,000–13,000 years ago the Laurentide ice sheet fused with the Cordilleran ice sheet, which blocked gene flow between Beringia (and Eurasia) and continental North America.

Boundaries between the continents of Earth Europe and North America are separated by the North Atlantic. In terms of associating islands with either continent, the boundary is usually drawn between Greenland and Iceland. The Norwegian islands of Jan Mayen and Svalbard in the Arctic Ocean are usually associated with Europe.

Pangaea, Gondwanaland, Laurasia and Tethys a large supercontinent that existed in the southern hemisphere, clustered near the Antarctic Circle, before it began to break up ~200 million years ago, consisting of the modern day continents of Antarctica, India, Australia, South America and Africa. Breakup of Gondwanaland.

This History of the Supercontinent Pangea In the case of Pangea nearly all of the Earth's continents were connected into one large landmass. It is believed that Pangea began forming about 300 million years ago, was fully together by 270 million years ago and began to separate around 200 million years ago.The name Pangea is ancient Greek and means all lands..angea began to break up about 200 million years ago as a result of the movement of the Earth's tectonic plates and mantle convection.

- Back to the question: the evidence for a land bridge is twofold: (1) the topology and depth of the ocean floor in the Bering strait, and (2) geological evidence of significantly lower sea levels at the time in question.
