1100 mya (million years ago) the 1st known supercontinent was formed , Rodinia, thru a series of chemical reactions over the course of M.Y.A. Millions of yrs of rain coupled w/ the moving crust, allowed bodies of granite to rise from the oceanic world. Rodinia was a barren wasteland for it's time, (this era known as "snowball earth")but it would usher in a baby-boom of marine organisms. Thus the oceans turned blue & beneath the earth the continental " drift" was on the move. The 2nd configuration is hypothetical to most scientists it has become known as Pannotia(600-540 Mya). Pannotia comes from greek for "all seas", this is due to the Iapetus ocean tearing Rodinia apart.
It was made up of our land masses today but continental drift came and moved the continents
It wasn't three continents it was all of them.
The two continents that people came to America were from Europe and Africa.
The supercontinent that split into today's continents is called Pangaea. It is believed to have been a single landmass around 335 million years ago before breaking apart into the continents we have today.
there are seven continents in the earth in 2011 right now
The shape of the continents is mainly due to water erosion.

The movement of tectonic plates over millions of years has shaped the continents' current positions. This process, known as plate tectonics, causes continents to drift apart, collide, and converge. The distribution of continents we see today is a result of this ongoing movement.
The continents that were part of Gondwana land are Australia, Antarctica and South America.
Yes, Earth's continents are still moving today due to plate tectonics. This movement is very slow, with continents drifting at a rate of a few centimeters per year. The movement of continents causes earthquakes, volcanic activity, and the formation of mountain ranges.
