How many years have the people on the 7 continents been there?
There have been many forms of humans on the planet over the last at least 400,000 years. The human race that now lives on the earth (homo sapiens) developed some 200,000 years ago.It took quite a while before they had spread over all the continents on the planet. They started spreading over the continents some 70,000 years ago and they finished spreading to all the continents some 15,000 years ago.

How many years ago were all the continents joined?
Around 200 million years ago, all the continents were joined together in a supercontinent called Pangaea. This event is known as Pangea's formation during the late Paleozoic and early Mesozoic eras. Over time, Pangaea began to break apart, eventually leading to the continents we see today.
What do many science believe about the earth continents?
That at one time in the past many many millions of years ago they were all joined together forming just one super continent.
What was pangaea and what has happened over the many years to the continents?
Pangaea was a supercontinent that existed about 335 million years ago and eventually broke apart to form the continents we have today due to the movement of tectonic plates. Over millions of years, the continents have drifted apart, leading to the formation of new oceans and mountain ranges as a result of plate tectonics.
When many monosaccharides are joined together?
When two to ten monosaccaharides are joined together they are called as oligosaccharides ,and polymer of hundred to thousand monosaccharide joined they are called as polysaccharide.
How many continents are south and North America divided into?
They are continents. Unless, because they are joined, you consider them part of a single continent, i.e. America.
What evidence supported continental drift?
the same rock types on the edges of different continents and the reverse magnetic polarity show seafloor spreading which shows that the continents are moving. the Coastlines of South Africa and south ameria seem to match and fit together like a jigsaw and so do many other countries which gives the impression that all the continents were onced joined together as a massive continent called Pangaea

How many times have all of Earth's continents come together to form a super-continent?
It is estimated that Earth's continents have come together to form a super-continent around three times in the last 600 million years. This cycle of continents coming together and then breaking apart is known as the supercontinent cycle. Examples of supercontinents include Pangea, Rodinia, and Columbia.
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.
