3 ways to prove the supercontinent pangaea exsisted?

Question

supercontinent pangaea was when all the continents were formed together.

Answer 1

These are my best guesses (with help from the source below):

1) It could be done by looking at the shape of the continental coastlines and seeing how they might fit together as a puzzle.

2) Also by looking at the geology between two seperate continents. (Distinctive rock strata).

3) Fossil distribution

4) Coal distribution

Answer 2

1) The shapes of all of the continents match, and look like they could fit together like a jigsaw puzzle.

2) The species on the continents match. About 80 years ago, noted geologist Alfred Wegener noted that plant fossils of late Paleozoic age found on several different continents were quite similar. This suggests that they evolved together on a single large land mass. He was intrigued by the occurrences of plant and animal fossils found on the matching coastlines of South America and Africa, which are now widely separated by the Atlantic Ocean. He reasoned that it was physically impossible for most of these organisms to have traveled or have been transported across the vast ocean. To him, the presence of identical fossil species along the coastal parts of Africa and South America was the most compelling evidence that the two continents were once joined. Also, fossils very similar to the Platypus have been found in South America. The fossil wasn't a platypus, and was a much larger animal, but the skulls were nearly identical, and other anatomical comparisons between the two species' skeletal features show very clearly that the South American specimen was a relative, even if not a direct ancestor.

3) The rocks match. Broad belts of rocks in Africa and South America are the same type. These broad belts then match when the end of the continents are joined. The match is made in both composition, and isotopic age.

Also, the magnetic orientation of volcanic rocks indicate that the continents were in a totally different position. When molten lava is ejected from a volcano, the atoms of magnetic material in the rock (Mostly Iron, but other metals as well) settle in an orientation that aligns with the magnetic field of the earth. Once the rock had cooled and hardened, these atoms are locked in place, forever pointing in the same direction. However, if the entire continent on which the volcano in question spins, over millions or billions of years, then these atoms will no longer be pointing north. The only two explanations for this is that the atoms moved within the rock after it hardened (which we know doesn't happen) or that the continents moved. Using applied plate tectonic theory, one can determine at what point two continents would be close together, and where on the globe that would have occurred. One would then predict that the magnetic atoms would be aligned north at that point. This has been tested, and the observations fit the predictions.

4) The positions don't match. If the continents were cold enough so that ice covered the southern continents, why is no evidence found for ice in the northern continents? Simple! The present northern continents were at the equator at 300 million years ago. The discovery of fossils of tropical plants (in the form of coal deposits) in Antarctica led to the conclusion that this frozen land previously must have been situated closer to the equator, in a more temperate climate where lush, swampy vegetation could grow.

5) The fact that the continents have been verified to still be moving, and in the predicted directions and speed that would have predicted Pangaea if the clock were turned backward, further supports the supercontinent theory.

6) Each of these individual metheds supports each other to a very high degree.

Answer 3

If yet another great continent does type returned, it may well be a various shape than Pangaea. because of the fact of abrasion the sides of at present's continents are a various shape. extra, plate tectonic activity has performed a great function in reshapig the continents.

Answer 4

1. The fact that the shapes of the continents look like they fit together

2. The fact that the minerals are similar where the continents' borders were together

3. The fact that the continents are still drifting

Answer 5

I d believe that it existed. In the old testament there's a portion that lists the name Peleg & in parenthesis (which means earth divided for in his day the earth was divided.)

There is a book you can read only called "In the Days of Peleg" that discusses this topic in great depth. Perhaps it may assist you in getting the answers you need. See the link below for that info.

Answer 6

RE: Crush 33. China/Asia will never rule the world. Bible does reference that the "Kings of the East" will mount an army of 200 million, but read on as to what happens to them, its called Armageddon. Maybe they should be happy making our DVD players.

Answer 7

Many areas of the world fit toegether with china and since i am asian and asian people will eventually rule the world you must say pangeae exists. Or the chinese will do harm on to everyone. (mook)

Answer 8

Sure, geologists have been working on this and have concluded it did exist. I can't tell you why. But, I know that it has been determined to have existed.

Answer 9

Is there a question here? All you have written is a prepositional phrase!
