Scientist say that all the continents were once joined but however when the plate tectonics moved upward and downward they separated, and that's why they are supposedly not joined any longer.
Pangaea. But this was just the most recent of the super-continent agglomerations. There may have been at least two previous super-continents that eventually broke up and then re-formed in a different association.
Alfred Wegener, a German meteorologist, first proposed the theory of continental drift in 1912. He suggested that a supercontinent he named Pangaea had existed and later broke apart to form the continents as we know them today.
Pangaea was a supercontinent that existed about 300 million years ago, when all the Earth's continents were joined together as a single landmass. The plates that make up the Earth's crust shifted over time, breaking apart Pangaea into the continents we know today.
The fact that similar fossils are found on both sides of the ocean is evidence of past land connections between continents, such as Pangaea. This supports the theory of continental drift, where continents were once joined together and have since drifted apart.
Alexander du Toit discovered evidence for continental drift in the early 20th century. He proposed that the continents were once joined together in a single supercontinent called Pangaea, and that over time they drifted apart to form the continents as we know them today. His work laid the foundation for the theory of plate tectonics.
Evidence of continental drift includes the matching shapes of continents, similar fossils found on different continents, and geological features that align across separate continents. These clues suggest that the continents were once joined together in a single landmass called Pangea.
At one point in history, the continents were joined together as a supercontinent called Pangaea. Over time, the movement of tectonic plates caused the continents to drift apart to form the world map we know today.
When Earth's continents were joined together in a supercontinent called Pangaea about 300 million years ago, the landmass looked like one giant landmass surrounded by a single ocean called Panthalassa. This configuration eventually broke apart due to plate tectonics, leading to the continents we have today.
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.
the ocean sea floor is spreading
Pangaea. But this was just the most recent of the super-continent agglomerations. There may have been at least two previous super-continents that eventually broke up and then re-formed in a different association.
The supercontinent that all continents were once joined to is called Pangaea. It existed during the late Paleozoic and early Mesozoic eras before breaking apart into the continents we know today.
When all continents were connected, they were part of the supercontinent called Pangaea. Pangaea existed during the late Paleozoic and early Mesozoic eras, before breaking apart into the continents we know today.
Approximately 335 million years ago, all the Earth's continents were joined together in a supercontinent called Pangaea. Over time, due to the movement of tectonic plates, Pangaea began to break apart, leading to the formation of the continents as we know them today.
because he didn't know how the tectonic plates/continents moved
Pangaea was a supercontinent that existed about 335 million years ago, and it included almost all of Earth's landmasses joined together. It had a distinctive single landmass configuration, with some of the current continents as we know them today joined into one large landmass.
Alfred Wegener, a German meteorologist, first proposed the theory of continental drift in 1912. He suggested that a supercontinent he named Pangaea had existed and later broke apart to form the continents as we know them today.
