this supercontinent is called PANGEA. it is the greek word for "all lands".

∙ 10y agoThe hypothesis is that of Plate Tectonics, or Continental drift.
Pangea, is the most recent assembly of the continents, and their break-up. Many scientists thought that all the continents were once a huge land mass surrounding by all the oceans. It is said that plate tectonics then moved the continents apart over millions of years and made the world look like it does today.
Modern thinking is that the aggregation of the continents and their subsequent break-up has occured several times. Have a crack at supercontinent cycles in a reference work such as wikipedia.

What hypothesis states that the continents were once joined to form a single supercontinent?
If put together, they would fit perfectly into one huge super continent like a puzzle.
What is Wegeners hypothesis?
Wegener hypothesized that, on earth, there was only one continent called Pangea, but it split into the continents we have now.Improved Another Answer:Wegener's hypothesis was that long 225 million years ago, there was a supercontinent called Pangaea (All the continents were all together).Wegener saw that South America and Africa looked like they could fit together like puzzle pieces. He then found that there were fossils of animals in a warm climate and it was also in a very cold climate. He thought, "How could that be? The animal couldn't have lived in two different kinds of climates and how could it have swam across the sea?!"
Who was alfred wagner?
Wagner , a german, was the first to speculate the continents were once joined together and somehow drifted apart. This was i believe in 1911. Now we know the method of movement sea floor spreading. at one time this mass land mass was called pangea.
What evidence did wegener gather to support his continental drift hypothesis?
Well it wasn't so much climate as the fossils that have been found. Fossils have been found in Antarctica of plants that only occur in tropical climates so at one point it must have had a tropical climate. That is the most dramatic example but there are more subtle ones that led him to believe that the continents, at one point, must have been in different locations on the Earth and then moved to where they currently are.
Why Wegener interested in finding fossils of the same plants and animals on two different continents?
The answer is quite simple. Millions and billions of years ago, the Earth was one land. This was called Pangea. However, due to plate techtonics, they move the land around and over time, these lands split apart. After enough time has elasped, these gaps would become oceans. For example, when the continents were together as pangaea the animals roamed freely, but when they split apart the animals were split up. So a plant or animal fossil may be the same on the eastern coast of South America as it is on the western coast of Africa.
Why is continental drift called a hypothesis?
the Hypothesis is Based on an apparent fit between Africa and South America,Wegener hypothesized that at one time all continents were joined together in a "supercontinent" called Pangaea. The supercontinent eventually broke into the smaller continents, which then "drifted" towards their present positions.
What was the name of the supercontinent that was hypothesis to have existed when all continents had been joined?
Pangea
What hypothesis state that the continents were once joined to form single supercontinent?
this supercontinent is called PANGEA. it is the greek word for "all lands".
What is the hypothesis that the continents move slowly over earths surface and once were joined into one supercontinent?
Continental drift.
The theory that the continents were once joined and then slowly drifted apart is called what?
The Pangaea theory or the Expanding Earth theory posits that the Earth originally had one supercontinent that slowly divided. Pangaea is the name of the supercontinent.
Who developed the idea that continents were once joined and have since drifted apart?
wegener
What was the one supposed supercontinent?
Pangaea, which was the supercontinent made out of all of today's continents joined together. It existed 250 millions years ago.
What its the theory that the continents we're once joined and slowly drifted apart?
Continental Drift.
What is the large ancient landmass composed of all the continents joined together?
That supercontinent was called "Pangea".
State the hypothesis of continental drift?
That there was once a super continent called Pangaea huge land mass was broken into continents that drifted apart. The theory also suggests that the earth is made up of 7 gigantic shifting slabs of the earth's crust. This disproved the more popular (at the time) "raisin" theorem
As hypothesized by Alfred Wegener what is the history of Earth's continents?
They were joined together, then drifted apart to their current positions
Who proposed that all of the present continents were once joined together in a single supercontinent called Pangaea?
Alfred Wegener
