What is the evidence for Pangaea splitting in the mid Jurassic?

. The main piece of fossil evidence, however, for the existence of Pangaea is the Glossopteris who's fossil records from the mid to late Triassic period spread in a band across South America, Africa, India Antarctica and Australia. The glossopteris plant arose in the Permian period and was extinct by the end of it, during the species life span it became very widespread across the Southern Hemisphere. This makes it a perfect organism to use for dating any sediment containing a glossopteris fossil came from the Triassic period and (after evolving into existence on the continent of Gondwana) spread, we assume, via land based organisms. It was one of the first large seed plants and was deciduous, meaning that every year it dropped a large amount of leaves, which have been found up to a meter in length. posted by matsbugs@hotmail.com. let me know if u need any more info on pangaea

Evidence for Pangaea splitting in the mid Jurassic includes geological similarities between continents that seem to fit together like a jigsaw puzzle, matching fossils on different continents, and the alignment of mountain ranges and rock formations across separate landmasses. Additionally, paleomagnetic data from rocks show how continents have moved over time, supporting the theory of continental drift.

What is proof of theory of plate tectonics developed?
The theory of plate tectonics is supported by evidence such as the matching coastlines of continents, distribution of earthquakes and volcanoes along plate boundaries, and the mapping of magnetic striping on the ocean floor. Additionally, studies of mid-ocean ridges and subduction zones provide further evidence for the movement of Earth's lithospheric plates.
Does subduction occur at the mid ocean ridge?
No, the Mid Atlantic Ridge is where the two plates are diverging, which creates more oceanic floor.
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic Ridge
What island is north Atlantic is splitting apart?
The island that is currently splitting apart in the North Atlantic is Iceland. It is located on the Mid-Atlantic Ridge, a divergent tectonic boundary where the North American Plate and the Eurasian Plate are moving apart, causing new crust to form and the island to expand.
Are Magnetic bands on either side of the mid-Atlantic ridge able to provide evidence for plate tectonics?

What scientific evidence supports the theory of Pangaea?
Scientific evidence supporting the theory of Pangaea includes the fit of the continents' coastlines, similarities in rock formations and geological structures across continents, and matching fossil evidence of ancient plants and animals. Additionally, the distribution of certain species among continents and the discovery of mid-ocean ridges and plate tectonics further support the concept of Pangaea.
How do scientists know Pangaea was together?
Scientists know Pangaea was once together because of several lines of evidence, including matching rock formations and fossils across continents, as well as the fit of the continents' coastlines like puzzle pieces. Additionally, evidence from plate tectonics theory, such as the movement of continents over time and the presence of mid-ocean ridges, supports the idea of Pangaea's existence.
When was Pangaea finally accepted as true?
The concept of Pangaea, a supercontinent that existed millions of years ago, was first proposed by Alfred Wegener in 1912. However, it was not widely accepted by the scientific community until the mid-20th century when supporting evidence from paleontology, geology, and plate tectonics emerged.

When was pangaea discovered?
The concept of Pangaea, the supercontinent that existed approximately 335 million years ago, was first proposed by Alfred Wegener in 1912 based on geological and paleontological evidence. However, the idea was not widely accepted until further evidence, such as plate tectonics, was discovered in the mid-20th century.
What did sea floor spreading do to Pangaea?
Sea floor spreading contributed to the breakup of Pangaea by creating new oceanic crust at mid-ocean ridges, causing the continents to drift apart. This process resulted in the formation of the Atlantic Ocean and the separation of the once-contiguous landmass Pangaea into multiple continents.
What is proof of theory of plate tectonics developed?
The theory of plate tectonics is supported by evidence such as the matching coastlines of continents, distribution of earthquakes and volcanoes along plate boundaries, and the mapping of magnetic striping on the ocean floor.

Does subduction occur at the mid ocean ridge?
No, the Mid Atlantic Ridge is where the two plates are diverging, which creates more oceanic floor.
What is boudary is Iceland in?
Iceland is splitting along a Mid-Atlantic Ridge a divergent boundary between the North American and Eurasian Plates.
What proof do scientists now have to prove the theory of Pangaea?
Scientists have found evidence supporting the theory of Pangaea through the study of fossil records, similarities in rock formations and mountain ranges across continents, and the fit of coastlines. Additionally, advancements in plate tectonics have provided further insight into how the continents once formed a single supercontinent.
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic Ridge
What island is north Atlantic is splitting apart?
The island that is currently splitting apart in the North Atlantic is Iceland. It is located on the Mid-Atlantic Ridge, a divergent tectonic boundary where the North American Plate and the Eurasian Plate are moving apart, causing new crust to form and the island to expand.
