Wegener thought that all of the present continents were once joined 245 million years ago in a landmass he called?
The last super-continent is called Pangaea, which was formed about 245 million years ago.
Some believe that Pangaea wasn't the first time all the continents were combined. There is evidence that there was another super-continent way before 245 million years ago that is called Rodinia (which separated for a while, then formed back together to form Pangaea, the latest super-continent).
What else can I help you with?
Which theory explains how the continents drifted from one landmass to their present location?
pangea
What did Alfred Wegener and what did he theorize?
Alfred Wegener was a German scientist who was the first one to discover the continental drift. In 1915, Alfred Wegener, suggested that about 300 million years ago all of Earth's land masses, which were in constant motion, collided to form one supercontinent. He called it Pangaea , which means " all land". About 200 million years ago, the supercontinent of Pangaea started to break up. The pieces drifted in different directions to their present positions. Wegener had 4 proofs for his theory of continental drift. Most scientists did not accept the theory because Wegener could not explain what force was powerful enough to move continents. Wegener tried to prove his theory: He saw the jigsaw fit between South America and Africa. He found fossils of the same plants and animals on both continents. He believed that they exist in both places only if the continents were once joined together. It was not until the 1960's that the technology existed to develop Wegener's theory further. By 1968, a new and more complete theory known as plate tectonics had been developed.
As hypothesized by Alfred Wegener what is the history of Earth and the continents?
Alfred Wegener proposed the theory of continental drift, suggesting that the continents were once joined together in a supercontinent called Pangaea and have since drifted apart. Over time, these continents have moved to their current positions, leading to the present-day arrangement of landmasses on Earth. This theory laid the foundation for modern plate tectonics.
Were is pangeau?
Pangaea. "All the World." It's gone. It was the supercontinent that existed at the beginning of the Age of the Dinosaurs. Its counterpart was Panthalassa, "All the Sea." It broke up by 64 million B.C. and the present continents (Africa, Asia, the Americas, etc.) are parts of it.
What is the difference between earth now and when it was Pangaea?
Pangaea was a supercontinent that existed around 335 million years ago, while Earth now is divided into several separate continents. The major difference is in the landmass arrangement, as Pangaea was a single large landmass, whereas the current continents are separated by oceans. Additionally, the climate, ecosystems, and species distribution were different during the time of Pangaea compared to the present day.
A landmass thought to have been comprised of present-day southern continents?
Gondwanaland is a landmass thought to have been compromised of present-day southern continents.
What was Abraham ortelius hypothesis?
The hypothesis that the continents had once formed a single landmass before breaking apart and drifting to their present locations was fully formulated by Alfred Wegener in 1912. Although Wegener's theory was formed independently and was more complete than those of his predecessors, Wegener later credited a number of past authors with similar ideas
What was the landmass called before the continents separated into their present orientation?
Pangea, also spelled pangaea or pangæa. The wikipedia article is probably a good place to start, if you want to find out more about it.

How can you explian Pangaea?
Pangea was the giant supercontinental landmass that existed on the Earth's surface about 250 million years ago. It was essentially all of the present continents 'stuck together' in one large grouping. It is proposed by plate tectonics that the movement of tectonic plates moved portions of this landmass apart and around the world, forming the present continents in their existing distribution.
Who proposed that all of the present continents were once joined together in a single supercontinent called Pangaea?
The theory that all present continents were once joined together in a supercontinent called Pangaea was proposed by Alfred Wegener in 1912. He suggested that over time, Pangaea broke apart into the continents we see today, a process known as continental drift.
What did Alfren Wegener present as evidence that the continents move?
Alfred Wegener presented several lines of evidence to support his theory of continental drift, including the fit of the continents like a jigsaw puzzle, similarities in rock formations and mountain ranges across continents, and the distribution of fossils of the same species on different continents separated by oceans.
What evidence is there that the present-day Continent were once a single landmass?
One piece of evidence that indicates the continents were once connected is the shape of the continents. Many of the continents look as if they fit together like a puzzle.
Which theory explains how the continents drifted from one landmass to their present location?
pangea
How are the continental drift theory to the present positions of the continents related?
They are spread apart now because before the were one big landmass.
