It has definitly been more than once since there has been earth for about 4.5 billion years. The most recent is Pangea
Five hundred million years ago, Pangaea was put together. During the centuries, Pangaea was connected numerous changes above and below the land. Soon after Pangaea, the plates under it touched then started moving away the other plates. Pangaea was a landmass that included all of the present day continents and was on this Earth for many, many millenniums.
There have been several cycles of supercontinent formation and breakup in Earth's history. Some of the well-known supercontinents include Rodinia, Pannotia, Gondwana, and Pangaea. These supercontinents formed and broke up over hundreds of millions of years due to the process of plate tectonics.

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.
No. Pangaea was formed many, many millions of years before Christ
Actually according to my scientific calculations Pangaea means all Earth toghether.So 1 because at the time it was Pangaea all the land masses were together.
There were originally one supercontinent called Pangaea that eventually split into the continents we have today.

About 50 earth quakes occur in each day so we can say that 18250 to 20000 earth quick occur a year.
i think 94 kinds of atoms occur to earth
94 kinds of atoms occur naturally on earth

Nine times.
1000 times
20 times
During the time of Pangaea, most landmasses were concentrated together as a supercontinent, so there weren't many individual islands like Hawaii or Easter Island. Most of the Earth's surface was part of Pangaea, with few separate islands. It was only after the breakup of Pangaea that the continents shifted to create separate islands as we see them today.
once but in the distant future the continents will thus drift together hence creating another supercontinent.
