Yes, they were. The combination of the continents was called Pangaea.
Yes, millions of years ago, all the continents formed one giant landmass called "Pangaea". A word from the ancient Greek. PAN=ENTIRE+GAIA=EARTH. [Latinized as GAEA].
Pangaea it existed during the Paleozoic and Mesozoic eras before slowly splitting apart and forming the continents today.
The largest single landmass on Earth is Afroeurasia (the continents of Africa, Europe, and Asia). It occupies 85,000,000 km2, or about 5 times the size of Russia.
The theory of continental drift did originate in the 1930s. Continental drift asserts that the continents were once a single landmass called Pangaea that drifted apart over time.
That there was once a super continent called Pangaea huge land mass was broken into continents that drifted apart. The theory also suggests that the earth is made up of 7 gigantic shifting slabs of the earth's crust. This disproved the more popular (at the time) "raisin" theorem
It wasn't three continents it was all of them.
The continents do not "drift" in the usual sense of the word. They are held tightly together on the numerous plates, and move because they are being pushed, squeezed, and/or lifted. At no time are they free to move about with no other plates packed around them. Continental Drift is a theory developed in the 1900s by a German scientist named Alfred Wegner. He believed that the continents all fitted together at one point and published a book explaining it in 1915. He believed that the Earth 200 million years ago had one large landmass, aka Pangaea. His theory stated that the Earth's continents split up over time to create the continents we know today. He believed that this could be proven, and found a 250 million seed fern whose seeds could not travel long distances (not over oceans). Wegner died in a blizzard in Antarctica looking for the fern after he found it on other continents. Not until the 1960's did scientists find the fossil evidence to be good enough to prove that all land was joined at one point in time. Sea-floor spreading is another phenomena that science finds to be proof of Pangaea.
All the continents used to be one large landmass. It was called Pangea. Later on, the landmass started drifting apart little by little. Eventually they became continents.
a continental theory
the name for continents in one landmass surrounded by gigantic ocean
Alfred Wegener.
Alfred Wegener.
It is actually the name of the super continent - when all the continents were one landmass.
Australia
Alfred Wegener.
All continents have landmasses that narrow. In fact, all continents are wider in the north than in the south. It is unknown why.
Alfred wegener came up with the theory of continental drift, when all of the continents were together as one the landmass was called Pangea
Pangea
the answer is it was pangaesa
