What the world used to be like.

This is what the earth used to look like before the continental drift. The picture below is Pangaea a super continent made up of the continents we see today.

In the 1900's, a German meteorologist by the name of Alfred Wegener was the first to present an argument supporting continental drift. He proposed that the continents were not stationary, but actually moving or drifting away from one another. His primary sources of evidence included the fit of the continents, glacial till deposits, and the apparent shifting of climatic belts over time. His colleagues at the time argued for polar wandering as an explanation of his data. These ideas were not well accepted until later scientists in the 1940's and 50's expanded on these ideas adding to them paleomagnetism, convection currents and sea floor spreading. With all this new evidence, plate tectonic theory became an accepted idea in the 1970's.

Wegener noticed that the continents seemed to fit together, not at the continuously changing shoreline, but at the edge to their continental shelves. He derived this hypothesis from the observation that the continents in the southern hemisphere exhibit an identical pattern of rock and fossils known as the "Gondwana sequence". The most logical explanation was that the continents themselves were once parts of a much larger "super-continent" which was named Pangaea.

This video below shows the way the earth has changed in the last 600 million years.

Formation of the Earth

The Earth is thought to have been formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. Gravity slowly gathered this gas and dust together into clumps that became asteroids and small early planets called planetesimals.

Plate Tectonics.

Plate tectonics says that the Earth's strong outer layer (called the lithosphere, which consists of crust and uppermost mantle) is broken into a mosaic of plates that slowly move over a mechanically weaker layer (the asthenosphere, which is part of the upper mantle). Where these plates interact, major geological processes take place, such as the formation of mountain belts, earthquakes, and volcanoes.

What will the Earth look like in 100 million years.

Based on  scientific research the next super continent will be in between 50 million and 200 million years from now .
