Why was the hypothesis about the super continent Pangaea rejected?
The hypothesis of the supercontinent Pangaea was not rejected, but rather supported by geological evidence such as matching rock formations, fossils, and mountain ranges across different continents. The concept of plate tectonics provided a framework to explain the breakup of Pangaea into separate continents over time.
In what time period did Pangaea start to break up?
Pangaea started to break up during the Triassic Period. It continued to split apart in the Jurassic Period and was almost complete in breaking up in the Cretaceous Period. After that it formed into the landmasses that we see today.
What is a break in the geological record?
A break in the geological record refers to a gap in the sequence of rock layers, known as stratigraphic discontinuity, where no deposition or preservation of rocks occurred. These breaks are often caused by erosional processes, tectonic events, or periods of non-deposition. They represent missing time periods in the Earth's history.
How do pangaea works?
Pangaea was a supercontinent that existed about 300 million years ago, where all the Earth's landmasses were joined together. Over time, plate tectonics caused Pangaea to break apart and drift to form the continents we know today. This movement is still ongoing, with the continents slowly shifting positions on the Earth's surface.
Why is pangaea important?
Pangaea is important because it provides evidence for the theory of plate tectonics, helping us understand how Earth's continents have moved over time. It also explains the distribution of fossils and geological features across different continents, helping scientists reconstruct the Earth's history and evolution. Studying Pangaea helps us better comprehend the dynamic nature of our planet and its ever-changing landscape.
What does the geological timescale encompass?
IT encompasses all of the geological time period that have happened since the begin of time
All continents were once connected as one large landmass are now called?
The supercontinent that existed when all continents were connected is called Pangaea. Over time, Pangaea began to break apart due to tectonic movements, eventually forming the distinct continents we have today.
Which continent changed its position least since Pangaea?
Antarctica is the continent that changed its position the least since Pangaea. It has remained relatively close to its original location near the South Pole throughout geological time.
How the theory of the plate tectonics relates to the formation and break up of pangaea?
The theory of plate tectonics explains that the Earth's lithosphere is divided into tectonic plates that float on the semi-fluid asthenosphere beneath. Pangaea, the supercontinent that existed around 335 million years ago, formed as these plates converged and collided, bringing landmasses together. Over time, the movement of these tectonic plates caused Pangaea to break apart, leading to the current configuration of continents as they drifted to their present locations. This ongoing process continues to shape the Earth's surface and geological features.
What will happen if continents combined?
that means we would have the Pangaea again *Pangaea was the supercontinent that existed during the Paleozoic and Mesozoic eras about 250 million years ago, before the component continents were separated into their current configuration.
What were the major geological events in the permian time period?
The major geological events in the Permian period include the assembly of the supercontinent Pangaea, widespread glaciation in the southern hemisphere, and the formation of the Siberian Traps volcanic province, which led to significant climate change and a mass extinction event known as the Permian-Triassic extinction.

Where was the Philippines located during the time that Pangaea existed?
During the time that Pangaea existed, the land that now makes up the Philippines was located near the equator within the larger landmass of Gondwana. As Pangaea began to break apart around 175 million years ago, the land that is now the Philippines started to drift northward.
Why did scientist reject the theory of Pangaea?
Scientists initially rejected the theory of Pangaea due to a lack of understanding of the mechanisms that could drive continental drift. At the time, there was no satisfactory explanation for how continents could move across the Earth's surface, as the prevailing geological theories emphasized stability rather than mobility. Additionally, the fossil and geological evidence that supported the idea of Pangaea was not widely recognized or accepted until later, when advancements in plate tectonics provided a clearer understanding of continental movement. These advancements ultimately validated many aspects of the Pangaea hypothesis, leading to its acceptance in the scientific community.

When did pangaea break up?
The first phase began in the Early-Middle Jurassic (about 175 Ma).
