Who proposed that the continents broken drifted apart from each other?
scientist Alfred Wegener
The theory of continental drift is most associated with the scientist Alfred Wegener. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other.
Who hypothesized that Pangea had once been together but drifted apart?
Alfred Wegener
In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning “all lands”), and over time they have drifted apart into their current distribution.
Who discovered Pangea?
meteorologist Alfred Wegener
German meteorologist Alfred Wegener first presented the concept of Pangea (meaning “all lands”) along with the first comprehensive theory of continental drift, the idea that Earth’s continents slowly move relative to one another, at a conference in 1912 and later in his book The Origin of Continents and Oceans (1915).
What stressed Pangea to break apart?
but, as we have seen, the Earth’s crust is not static. The direction of plate movement shifted over time and the continents began to pull apart rather than converge. Rifts developed in the curst, eventually breaking completely through the crust and leading to the breakup of the supercontinent.
What are the 4 evidence of continental drift?
The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
What are Wegener’s four pieces of evidence?
They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
What two major landmasses broke apart from Pangaea?
Pangaea begins to break up and splits into two major landmasses — Laurasia in the north, made up of North America and Eurasia, and Gondwana in the south, made up of the other continents. Gondwana splinters further — the South America-Africa landmass separates from the Antarctica-Australia landmass.
Will Pangea ever form again?
The answer is yes. Pangea wasn’t the first supercontinent to form during Earth’s 4.5-billion-year geologic history, and it won’t be the last. So, there’s no reason to think that another supercontinent won’t form in the future, Mitchell said.
How long did it take for Pangaea to break apart?
Pangaea formed about 270 million years ago and started to break apart about 200 millions years ago. But all of this happened gradually — large chunks remained joined for another 100 million years, so you can make different arguments about what time period can be included in the question about what lived on Pangaea.
Where can I find answers to questions about Pangaea?

What was the name of the land mass that formed Pangaea?
This animation shows the movement of the continents over the past 250 million years. It starts when dinosaurs roamed the earth. At that time, the continents were all together, forming one land mass called Pangaea. Over the next 250 million years, the land mass broke apart and the pieces travelled to their current positions.
How did animals adapt to life in Pangaea?
Birds and mammals were poised to dominate the landscape with their useful adaptations as conditions changed yet again when Pangaea was breaking up. So life, which started out in warm shallow waters, spread to every sort of habitat on Pangaea.
