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).

Which theory explains how the continents drifted from one landmass to their present location?
pangea
Does the continents landmasses affect weather climate?
This is possible. A landmass is a continent or other large body of land. However, what's present on this landmass can affect weather. For example, carbon emissions presented by humans affects weather.
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.
How can Wegener's granulomatosis be prevented?
At present, there are no preventive measures known for Wegener's granulomatosis.
What is the earths land masses?
Earth's landmass is the part of earth total area that is covered by land and solid mass; it occupies about 21% of earths total surface area. Earth's landmass consists of the soils, continents, rocks, vegetations, and every other landforms and structures present on the earths surface. Geographically we can say that the Earth's landmass is the areas ocupied by the crust, the lithosphere and the solid part of the biosphere.
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

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?
Alfred Wegener
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.
When were the continents separated?
The continents separated from Pangea about 200 million years ago. The continents were in there present state (with different shorelines) 50 million years ago.
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.
Does the continents landmasses affect weather climate?
This is possible. A landmass is a continent or other large body of land. However, what's present on this landmass can affect weather. For example, carbon emissions presented by humans affects weather.
