What hypothesis says that all the continents once were joined as a single supercontinent and have since drifted apart?
this supercontinent is called PANGEA. it is the greek word for "all lands".

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
Who proposed the hypothesis that the continents were once joined in a single supercontinent?
Alfred Wegener proposed the hypothesis of continental drift in 1912, suggesting that the continents were once joined in a supercontinent he called Pangaea. His idea laid the groundwork for the development of the theory of plate tectonics.
What is the hypothesis that proposed that earths continents were once joined in a single land mass?
The hypothesis that proposed that Earth's continents were once joined in a single land mass is called continental drift. This theory, formulated by Alfred Wegener in the early 20th century, suggested that the continents were once part of a supercontinent called Pangaea that later broke apart and drifted to their current positions.
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 hypothesis by Alfred wegener explains why continents seem to fit togethere?
Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined together in a single supercontinent called Pangaea. Over time, the supercontinent broke apart and the continents drifted to their current positions, explaining why they seem to fit together like pieces of a puzzle.
What Hypothesis States That The Continents Were Once Joined From A Single To Form Single Supercontinent?
The hypothesis that states the continents were once joined together in a single supercontinent is called "Pangaea." This theory suggests that due to the movement of tectonic plates, Pangaea eventually broke apart over millions of years to form the continents as we know them today.
State Alfred Wegener's hypothesis about how Earth's continents have moved?
Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined together in a single supercontinent called Pangaea. He argued that these land masses have drifted apart over time to their current positions.
The hypothesis that continents have moved is called continental?
The hypothesis that continents have moved is called continental drift. This theory suggests that Earth's continents were once joined in a single supercontinent called Pangaea and have since moved apart to their current positions.
Describe wegener's hypothesis of continental drift?
Alfred Wegener's hypothesis of continental drift proposed that the Earth's continents were once joined together in a single supercontinent called Pangaea. He suggested that over time, Pangaea broke apart and the continents drifted to their current positions. Wegener supported this theory with evidence like matching coastlines, similar rock formations, and fossil distribution across continents.
The theory that the continents were once joined and then slowly drifted apart is called what?
The theory that the continents were once joined and then slowly drifted apart is called "continental drift." This theory was proposed by Alfred Wegener in the early 20th century and later developed into the theory of plate tectonics.
What scientist who first proposed the theory that the continents drifted?
Alfred Wegener was the scientist who first proposed the theory of continental drift, which later developed into the theory of plate tectonics. He suggested that the continents were once joined together in a single supercontinent called Pangaea and have since drifted apart.
