Are the continents and oceans always been in the same positions they are today?
No, the positions of continents and oceans on Earth's surface have changed over millions of years due to the process of plate tectonics. Continents have drifted apart and collided to form new landmasses, changing the configuration of oceans. This movement is ongoing, with the positions continuing to shift gradually over time.
What was the name of the supercontinent that was hypothesis to have existed when all continents had been joined?
Pangea
The shapes of which two continents' coastlines led to early suggestions they had been joined at one time?
Two Continents Are Africa And South America .
Why did Wegener think that the continents might once have been joined?
Wegener noticed that the coastlines of continents seemed to fit together like puzzle pieces, and that similar fossils and rock formations were found on opposite sides of the Atlantic Ocean. He proposed the theory of continental drift, suggesting that the continents were once connected in a supercontinent called Pangaea and had since drifted apart.
Have the continents and the oceans always been in the positions they are in today?
No, the continents and the oceans have not always been in the positions they are in today. The Earth's tectonic plates slowly move over time through a process called plate tectonics. This movement has resulted in the continents shifting positions and the reshaping of the oceans over millions of years.
Continents had once been joined in one landmass called?
It is called Pangaea, about 245 million years ago
Have the continents on opposite sides of the Atlantic ocean generally been drifting apart?
Yes. The continents have been drifting around since Earth first got her oceans, or before. At one time, there were a group of continents clustered near what is now Antarctica . . . the entire remainder of Earth's surface was covered by oceans of water. They eventually drifted apart. The current arrangement of continents occurred fairly recently in Earth's 4.5 billion year age.
What did Alfred Wegener propose after looking at the rock sequences on different continents?
Because the rock sequences matched so well, he surmised that the continents might once have been joined together.
What do the glossopteris fossils tells us about the early position of the continents?
That they must have been joined up in the past because the same fossils could not exist on the continents given their current position.
