How did Alfred Wegener prove that pangaea existed?
truth is he couldn't prove it he tryed to show the scientists that the continents could have drifted but the scientists did NOT believe him
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
What did wegener hypothesis happened to the continents?
Alfred Wegner believed that continents moved because of earth's plates shifting. Because he could not prove why they moved because of the day in age he live, most scientist didn't believe him. Now, with the science we have today, scientists have proved that our continents shift about 2cm a year.
What caused the drifting of the continent?
The causes of the natural disasters and plus the wind could possibly tear the continents and make separate continents. Also there could have been a terrible earthquake that caused the continents to also separate.
What evidence do scientists have that all the continents were one large land mass?
There is evidence that the continents may have been close, because if you look at a map for the earth, it looks like the earth is a big puzzle. Saudi Arabia fits into Eurasia, South America can interlock with Africa, and if you moved all the little islands between US and Europe, the could slide in. As you can see, there is evidence that the continents may have been closer at one time.
What did scientists discover that showed that continents could move?
Scientist discovered tectonic plates

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.
What model developed so that scientists could explain that the continents have moved over millions of year?
Plate Techtonics
What do scientists believe happened to most ancient species?
Their environment changed and they could no longer survive.
Wegener's continental drift hypothesis was weakened because a viable mechanism for moving the continents was lacking?
Yes, they could not find a reason that would cause the movements of the continents. Now, scientists have discovered that the continents don't drift, but rather they are carried by tectonic plates.
What do the glossopteris fossils tell us about early positions 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.
What do the glossopteris fossils tell us about the early positions 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.
What do the glossopteris fossils tell us about the early position of the continents?
shows that all three continents were once connected (joined) together. because the 'exact' same fossil types were found in all three different continents, which are now split from each other.

Which continent could fit in several position?
There are a number of continents that could fit together in several different positions. Africa and South America are an excellent example.
Could all the continents fit into the pacific ocean?
All the continents could fit into the Pacificbasin.
