Glaciers provide evidence for the existence of Pangaea through glacial deposits and striations found in regions now located near the equator, such as Africa, South America, and India. These remnants indicate that these continents were once situated closer to the poles, where glacial activity could occur. Additionally, the alignment of rock layers and the presence of similar glacial features across continents support the idea of these landmasses being part of a single supercontinent. This evidence aligns with the theory of continental drift, which suggests that Pangaea existed around 335 million years ago.

Why is the existence of Pangaea a belief rather than a fact?
The existence of Pangaea is a scientific theory supported by evidence such as the fit of the continents, geological similarities, and fossil distributions. While overwhelming evidence supports the theory, it is still technically a hypothesis because we cannot directly observe the movement of the continents over millions of years.
How did wegener explain the existence of glaciers in the southern landmasses and the lush tropical swamps in North America Europe and Siberia?
Wegener explained the existence of glaciers in the southern landmasses and lush tropical swamps in North America, Europe, and Siberia through his theory of continental drift. He proposed that these regions were once part of a supercontinent called Pangaea, which allowed for climate zones to shift over time. As the continents drifted apart, areas that were once near the poles became tropical, while regions that were once warm moved to colder climates, leading to the formation of glaciers and swamps in their respective locations. This movement accounted for the geological and paleoclimatic evidence observed in different regions.
How did Wagner use fossil evidence to support his theory for Pangaea?
Alfred Wegener used fossil evidence to support his theory of Pangaea by demonstrating that identical fossil species, such as the freshwater reptile Mesosaurus and the seed fern Glossopteris, were found on continents now widely separated by oceans. This distribution suggested that these continents were once joined, allowing species to inhabit a continuous landmass. Additionally, he highlighted similarities in fossilized flora and fauna across continents, indicating a shared biological history that could only be explained by the existence of Pangaea. This fossil evidence bolstered his argument for continental drift, which was a key component of the Pangaea hypothesis.
Is it true that Alfred wegner provided evidence from landforms and climate in support of his theory of the shrinking earth?
No, Alfred Wegener provided evidence from continental drift and fossil distribution to support his theory of plate tectonics, not a shrinking Earth. Wegener's theory suggested that the continents were once connected in a single landmass (Pangaea) and drifted apart over time due to the movement of tectonic plates.
What fossil was found on two different continents supporting Pangaea?
The fossil of the reptile Mesosaurus was found on both South America and Africa, providing strong evidence for the existence of the supercontinent Pangaea. This freshwater species could not have traversed the vast ocean that separated these continents, indicating that they were once joined. The discovery of such identical fossils on separate landmasses supports the theory of continental drift and the historical connection of continents.
What forms of evidence were used to help gather evidence for the existence of pangaea?
Plate tectonics led to the theory of Pangaea.

What forms of science were used to help gather evidence for the existence of Pangaea?
Geology, paleontology, and paleoclimatology were used to gather evidence for the existence of Pangaea. These sciences helped researchers study the geological formations, fossil records, and ancient climate patterns across different continents to reconstruct the supercontinent Pangaea.
How did mesosaurus and lystrosaurus provide evidence of Pangaea's existence?
Mesosaurus and Lystrosaurus provided evidence for the existence of Pangaea through their fossil distributions. Mesosaurus, a freshwater reptile, was found in both South America and Africa, suggesting these continents were once connected, as it could not have traversed the vast ocean separating them. Similarly, Lystrosaurus fossils were discovered in Antarctica, Africa, and India, indicating that these landmasses were once part of a larger supercontinent. The presence of these identical species across distant continents supports the theory of continental drift and the existence of Pangaea.
What evidence that supports the existence of pangaea?
There definitively was a Pangaea. Pangaea implies one continent. Back when the earth was forming, there was no oceans, thus the whole earth would be referred to as Pangaea. Today continents would refer to how much land is above the ocean.
Explain the evidence that supports the existence of Pangaea?
Evidence supporting the existence of Pangaea includes: Fossil evidence of similar species found on different modern continents. Rock formations and mountain ranges that match up when continents are rearranged. Paleoclimatic evidence, such as glacial deposits in regions that are now warmer. Similarities in geologic structures and ages of rocks across continents.
Why did most scientists not believe in Pangaea?
Because the earth was thought to be made by god, and it was perfect and no continental crusts. The existence of continental crusts is one of the many evidence that proved Pangaea to be a theory. Also, the existence of the fossil records of the same species along the coastlines of 2 different places confirms Pangea. The current movements in earth's crust also provide evidence that Pangaea could have formed. Most scientists were not given this data and therefore the evidence for Pangaea was vague. Only now has the evidence shown more consistency. Science is skeptical my friend.
What evidence may be called to prove that there once existed a super continent called Pangaea?
Evidence to prove the existence of the supercontinent Pangaea includes fossil evidence of similar plant and animal species across continents, the matching shapes of coastlines and mountain ranges on different continents, and the distribution of ancient rock formations that line up when continents are fitted together. Additionally, geological evidence such as rock layers and paleoclimatic data also supports the theory of Pangaea's existence.
Why is the existence of Pangaea a belief rather than a fact?
The existence of Pangaea is a scientific theory supported by evidence such as the fit of the continents, geological similarities, and fossil distributions. While overwhelming evidence supports the theory, it is still technically a hypothesis because we cannot directly observe the movement of the continents over millions of years.
Pangaea was in existence and invertebrates and amphibians were common?
When Pangaea was in existence, the main animals were reptiles and amphibians. During this time, birds developed also.
What are the existence of pangaea?
Pangaea was a supercontinent that existed about 335 million years ago and began to break apart around 175 million years ago, eventually forming the continents we recognize today. Evidence for Pangaea's existence includes the fit of the coastlines of continents, similar rock formations and mountain ranges across continents, and the distribution of fossils of the same species on different continents.
What proof did they have that Pangaea is real?
There is no direct proof. But there is evidence best explained by Pangaea having existed. This is the case with a lot of science, and looking for proof is not a very productive way to proceed. Proof works well only in mathematics.
