Before all of our continents split apart, due to tectonic activity, they were all together. Because of this, they were just one continent, called Pangea, which was a super continent. Evidence has proved that the continent did exist, because the same species of animals have been found all over the world.
When the continents were all together, they were called supercontinents. The Earth is thought to be 4.6 billion years old. The oldest theorized supercontinent is Vaalbara, which may have formed 3.3 billion to 3.6 billion years ago. The oldest known supercontinent is Ur, which formed 3 billion years ago. The Kenorland supercontinent formed 2.7 billion years ago. Columbia formed 1.8 billion to 1.5 billion years ago. Rodinia formed 1.1 billion to 750 million years ago. Pannotia, which also is called the Vendian supercontinent, formed 600 million to 540 million years ago. Pangaea formed 500 million to 200 million years ago. Laurasia formed 200 million years ago. And the last supercontinent was Gondwana. But that title may be held only temporarily by Gondwana. For the future may hold possibilities of one or two supercontinents within the next millions of years.
750 L is greater than 750 mL. There are 1000 milliliters in a liter, so 750 L is equivalent to 750,000 mL.
750 dL = 75 L
The two main ancient supercontinents are called Rodinia and Pannotia. Rodinia existed around 1.3 billion years ago and is believed to have broken up around 750 million years ago, while Pannotia existed around 600 million years ago and eventually broke apart around 540 million years ago.
750 million years ago, a single landmass, called Rodinia ( 1.1 billion to 750 million years ago ), broke up into more landmasses. 600 million years ago, they all came together, thus, Pannotia was born, only to break up in 514 million years ago. Once again, they came together to form Pangaea ( 300 million years ago to 200 million years ago ). 100 million years after it was formed, it broke into two; Laurasia the north, and Gondwana the south. In the present day, they still drift very slowly, but in about 250 million years in the future, a new supercontinent will form... ( but we, our children, grandchildren, great- grandchildren, ......, and our great-great-great-great-great ........... great-great-great grandchildren have already been long gone before this could happen )
The supercontinent that existed approximately 1.1 billion years ago was Rodinia. It was a precursor to Pangaea and consisted of most of Earth's landmasses at that time. Rodinia began to break apart around 750 million years ago.
A million is 1,000,000. So: 750 million = 750 * 1,000,000 = 750,000,000
Rodinia is the super continent that existed before Pangea.
Pollux, a giant star in the constellation Gemini, is estimated to be around 724 million years old.
The supercontinent that existed before Pangaea was called Rodinia. It formed approximately 1.3 billion years ago, broke apart around 750 million years ago, and eventually reassembled to form Pangaea around 335 million years ago.
According to geologists, a rodinia are segmented landmasses that come together and form a supercontinent. Studies indicate that rodinia existed between 1100 and 750 million years ago during the Neoproterozoic period when earths crust had broke.
Pangaea formed about 300 million years ago and began to rift about 200 million years ago.The formation and falling apart of super continents appears to be cyclical. Pangaea is the fourth super continent in Earth's history.Known super continents:Columbia (2 billion years to 1.8 billion years ago)Rodinia (1.1 billion years ago to 750 million years ago)Pannotia (600 million years ago to 540 million years ago)Pangea (300 million years ago to 200 million years ago)
Plants evolved around 750 million years ago.

The earliest continent currently theorised to have existed was Ur about 3 billion years ago. About 1.8 billion years ago Arctica, Baltica and East Antarctica merged forming Nena. Then about 1 billion years ago Nena, Atlantica, and Ur collided forming Rodinia which held together for about 750 million years. Finally about 300 million years ago Pangaea formed from Avalonia and Laurentia and was itself broken into Gondwana and Laurasia about 100 million later.
