What evidence is there of Pangaea from climate?

Fossils of tropical plants had been found on polar continents. The only way these plants could have possibly grown is if the continent had once been closer to the equator.

What is the Pangaea puzzle?

The Pangea puzzle is the theory of the beginning of the continents. It's how the Earth started out. Well it is the theory of how the continents came to be. The legend has it that way back in time, there weren't any continents. There was just one large landmass. Until it started to spread apart. That is when it was no longer just one piece. But there were 7 different landmasses. Over hundreds of thousands of years, those landmasses spread apart into what we know now as our 7 continents.

Scientific Method

Pangaea Supercontinent

Why is the earth's surface not expanding?

This is because when one divergent boundary is occurring (more sea floor being made), convergent boundaries are occurring (the sea floor is being consumed) on the other sides of the plates, such as what is occurring at the Mariannas Trench in the Pacific Ocean.

What are 3 types of plate boundaries and how are they different?

divergent plate boundaries move away from each other, convergent plate boundaries move toward each other, and transform plate bounties slide past each other.

What evidence did Alfred Wagner use to support his theory of continental drift?

Actually there is a lot of evidence that supported his evidence the big one was fossils of animals on distant continents and plants for example Glossopteris was one the strange reasons that Alfred was more than ever to prove his point.


Alfred Wegener proposed that, using 19th century longitude determinations, Greenland had moved 1 mile away from Europe. However, this conclusion ended up being false due to false calculations. Still, Wegener discovered that every year San Diego moved 6 feet closer to Shanghai while Washington D.C. and Paris got 15 feet closer. In addition, Alfred Wegener discovered that related species, too small to swim across the ocean, were found on different continental plates, as well as similar fossils.

Alfred Wegener's theory was rejected at first, however, because he was unable to explain the reason why the plates moved. Later, Arthur Holmes published his theory of thermal convection being the the thing that drove the plates apart. He also noted that the continents didn't "move" but were "carried" by larger pieces of the Earth's crust. Discoveries of the Mid-Ocean Ridge in addition to Harry Hess's work adds onto this theory of Wegener's.

As this theory is the most complete theory concerning global dynamics, the roots of such lie in the curiosity and work of Alfred Wegener.

Plate Tectonics

What layer of Earth makes up the plates and what layer causes them to move?

The layer of the Earth which makes up the plates is called the lithosphere. The lithosphere is composed of the continental and oceanic crusts along with the hard upper mantle.

What happened to Apollo 1?

Apollo 1 and her crew were destroyed in an electrical fire on board the spacecraft during a training session while on the launch pad. Gus Grissom, Ed White - the first US citizen to walk in space, and Roger Chaffee lost their lives within minutes, well before anyone could open the cumbersome hatch or even get close enough to the craft due to the intense heat. The training session had been plagued with problems, and Grissom was furious at the multiple problems the craft had. After the fire, the entire craft design was overhauled and the extra safety features quite likely preserved the Apollo 13 mission when the cabins became saturated in condensation, and it is thought the attention to insulating the wiring after the Apollo 1 fire prevented serious problems on Apollo13.

Pangaea Supercontinent

When did Pangaea exist in Earth's geologic history?

Laurasia and Gondwanaland collided to form a single supercontinent called Pangaea from the late Carboniferous Period, through the Permian Period of the Paleozoic era. Glacial deposits show that South America, South Africa, Antarctica, Australia, and India were close together near the south polar region at the middle of the Permian Period.
Pangaea was formed in the Late Permian and broke up in the Triassic Era.

What evidence did Alfred Wegener use to support his theory of continental drift?

Deep-sea mountain ranges had caught his attention.

Alfred Wegener's fully developed theory of continental drift attempted to point out evidences that the continents were once joined into a single continent he called Pangaea. Wegener's theory hypothesized that the continents were able to push through the rock of the seafloor to their present positions.

As evidence, he noted (as had others before him), of the geographic correlation in coastline perimeters of South America and Africa. This was the feature that led Wegener to investigate other clues. His investigations revealed that mountain ranges in South America and Africa, and strata and composition of coal fields in Europe and North America matched or lined up. Additionally, matching reptilian fossils were found on either side of the ocean, indicating that the continents were once joined together. Although he was unable to find a mechanism for his proposed continental drift theory, he also observed that the more shallow an ocean, the younger its geologic age. It wasn't until the 1950's and 1960's, with the discovery of the Mid-Atlantic Ridge (and other sea floor mapping discoveries) that Wegener's hypothesis started to become more accepted. The newer science of plate tectonics owes much to Wegener's scientific groundwork.
