Scientist say that all the continents were once joined but however when the plate tectonics moved upward and downward they separated, and that's why they are supposedly not joined any longer.

What is the name of the theory on the continents drifting apart?
Pangea is the original super continent that broke up into the continents we know today by a process known as 'Continental Drift' proposed by a scientist named Wegener
How do scientists know about continents once existing of landmasses?
There are two main evidences for this: 1. The continents fit together like a puzzle 2. There are both extant and extinct animal and plant species present on several continents that are not connected
How do scientists know that the continents were a big land mass?
If you are referring to Pangea, the theorized land mass that all continents were once part of, they know this because of the continents' puzzle like features, because things most likely exploded apart, causing the seemingly random shapes of the shores of the continents.
What is pangaea and what happened to it?
pangaea is all the continets together and an earthquake separated them a long time ago.
What convinced scientists that the the continents were slowly moving?
how an i suposed to know in a 3rd grader
How did earth look when continents were joined together?
When Earth's continents were joined together in a supercontinent called Pangaea about 300 million years ago, the landmass looked like one giant landmass surrounded by a single ocean called Panthalassa. This configuration eventually broke apart due to plate tectonics, leading to the continents we have today.
How do scientist know that the continents are moving?
the ocean sea floor is spreading
Why did scientist reject wegener's hypothesis?
because he didn't know how the tectonic plates/continents moved
Which continent was the first continent on earth?
The first continent wasn't any of the continents we have today. It was a lot of the continents that we know now, all joined together. It is known as Gondwala. The continent eventually broke up into the present day continents, eg. the east coast of South America used to fit into the west coast of Africa.
How do you know you have a mixture?
You know when you get a mixture because you get lots of elements but they are not joined together
How are the continents like a jigsaw puzzle?
they are like jigsaw puzzle because scientist don't know where places fit
What suggested to early cartographers that the continents were once joined?
The continent pieces fit together as if they where a puzzle. If you look at South America and Africa it seems that they could have once been connected.Fossil evidence in different countries implies that they may have once been joined. The fossils of large birds are the same implying that there was a common ancestor to large flightless modern birds that are separated on different continents.Mid ocean ridges are spreading the ocean floors apart. The age of the rocks on the bottom of the ocean shows that the plates that the continents are on are moving apart.Finally, the most compelling evidence is to do with the magnetism of the rocks. As the lava cools the ferromagnetic material in some rocks lines up with the Earth's magnetic poles. When these rocks move they are no longer lined up to the Earth's current magnetic poles, they produce anomalies in the magnetic readings. These rocks reveal their latitude of where they were when they cooled.

What is the name of the all continents joined together?
The name off all the continents joined together is Pangaea they were joined together more than 200 million years ago and started to drift apart due to the tectonic plates in the earths core. They are constantly moving apart. However we know that they were all joined together because fossils that were discovered in china are also being discovered in north America this is because dinosaurs used to walk over continents. The same soil and rock is being discovered in different parts of the world e.g. south America and Africa. Also we can tell this because if you draw it like a jigsaw puzzle you can see that south America and Africa join together. The pipelines going from America and England are also being pulled apart as the plates move further away from each other. India broke off from Africa and drifted apart until it crashed into Asia and the crash was so massive the Himalayan mountains were produced. India is still today moving more into Asia causing the mountains to grow bigger. This is proof that the continents once used to be joined together as one country called Pangaea.

Millions of years ago was Antarctica Australia South America and Africa joined together?
Pangaea was the original super-continent which broke up into Gondwanaland and Laurasia. Gondwanaland consisted of present day Africa, Antarctica, Australia, India and South America and began to break up about 250 million years ago.
What was the earth called when all countries were joined together?
