The theory that continents were connected as one large landmass was developed by Alfred Wegener in 1915 and is called continental drift. This is caused by molten rock on the sea floor spewing out between continents. If you look at the border of west Africa and East S. America they kind of fit together. It wasn't until 50 years later however that this was believed as at the time Wegener couldn't explain why they moved.
Hope that helps. :)

What is the theory that suggested the earth once had a supercontinent?
The theory that suggests the Earth once had a supercontinent is called Pangaea. It proposes that all current continents were once connected as one large landmass before breaking apart and moving to their current positions. The evidence for this theory includes the matching shapes of continents, similar geologic formations across different continents, and the distribution of fossils.
Earth's continents were once part of a single landmass called?
Pangea
What is the theory that the continents were once one giant landmass?
Alfred Wegner thought that all the continents used to be one giant landmass called Pangea. He said that the continents would move a little each year. The scientists didnt believe him though, but later found out that it could be true because of the plates in the earth
How do fossils support the idea of continental drift?
Fossils found on separate continents that were once connected suggest that landmasses have moved over time. Identical or closely related species of plants and animals found on different continents indicate that they were once part of the same landmass and have since drifted apart. This evidence supports the theory of continental drift proposed by Alfred Wegener.
What is the theory of Pangea?
The theory of Pangea proposes that all the continents were once connected as a single landmass about 335 million years ago. Over time, the landmass broke apart and drifted to their current positions, forming the continents we have today. This theory is supported by geological evidence such as the matching shapes of continents, rock formations, and fossils found on different continents.
Island that was once part of a large landmass?
Australia was once part of a large landmass. That large landmass was called Gondwanaland. Australia broke apart from Gondwanaland over 65 million years ago.
All continents were once connected as one large landmass are now called?
The supercontinent that existed when all continents were connected is called Pangaea. Over time, Pangaea began to break apart due to tectonic movements, eventually forming the distinct continents we have today.
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.
What is the name of the giant landmass that once contained all of the continents?
The giant landmass that once contained all of the continents is called Pangaea.
What is the theory that suggested the earth once had a supercontinent?
The theory that suggests the Earth once had a supercontinent is called Pangaea. It proposes that all current continents were once connected as one large landmass before breaking apart and moving to their current positions. The evidence for this theory includes the matching shapes of continents, similar geologic formations across different continents, and the distribution of fossils.
What are three pieces of evidence that the continents were once one large landmass?
Continents fit together like puzzle pieces - the coastlines of continents such as South America and Africa seem to fit together like pieces of a puzzle. Fossil evidence - similar fossils of plants and animals found on continents that are now far apart suggest they were once connected. Rock formations and mountain ranges - similar geological features and rock formations found on continents that are now separated indicate they were once part of the same landmass.
What evidence does the continental drift have that the continents were once connected?
Evidence for continental drift includes the fit of continents like South America and Africa, similar rock formations and mountain ranges on different continents, and the distribution of fossils that were once found on now widely separated landmasses. These pieces of evidence suggest that the continents were once connected in a single landmass called Pangaea.
What name did Alfred wegener gave his supercontinent?
Alfred Wegener named his supercontinent "Pangaea," which means "all lands" in Greek. He proposed the concept of Pangaea in his theory of continental drift, suggesting that all continents were once connected as one large landmass before drifting apart to their current positions.
The older theory of continental drift suggested?
that the continents were once all connected as one supercontinent, called Pangaea, which broke apart and drifted to their current positions over millions of years. This theory eventually led to the development of the theory of plate tectonics to explain the movement of Earth's large landmasses.
What is the name of the single landmass that once contained all continents?
Pangea
All continents once might have been connected in a large landmass called?
Pangea is the name of the latest super continent, but it is widely believed that there were more than one cycle of such "super continent, followed by breakup".Rodinia is the name given the immediate preceding super continent, and traces of at least one other are observed by believers.
What part of present day Eurasia was once a separate landmass?
The Indian subcontinent was once a separate landmass known as the Indian Plate. It is estimated to have separated from the supercontinent Gondwana around 100 million years ago, and eventually collided with the Eurasian Plate, leading to the formation of the Himalayan mountain range.
