yes, they all use to be together in a single landmass.
The early supercontinent that existed when Earth's landmasses were joined together was called Pangaea.
Yes, Africa and Australia were once part of the supercontinent called Gondwana, which existed during the Paleozoic and Mesozoic eras. Over millions of years, the breakup of Gondwana led to the separation of Africa and Australia to their current positions.
Matching coastlines are coastlines from different continents that seem to fit together like puzzle pieces. This observation led to the development of the theory of continental drift and plate tectonics, as it suggests that these continents were once joined together as a single landmass. A famous example of matching coastlines is the fit between the eastern coast of South America and the western coast of Africa.
are molecules are joined together to form elements
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.
Laurasia was the northern landmass that broke away from Pangaea. The modern day continents located in Laurasia were Europe (without Balkans), Asia (without India), and North America. Gondwana was the southern landmass that broke away from Pangaea. The modern day continents and countries located in Gondwana were Africa, South America, Australia, India, Arabia, Antarctica, and the European Balkans.
Europe and Asia are joined together by land, a connection known as the Eurasian landmass.
the continents were once joined together in a single landmass
Pangea
That supercontinent was called "Pangea".
Europe and Asia are joined into one large landmass known as Eurasia.
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.
A map of the continents (with the exclusion of Antarctica and the inclusion of Greenland) is included in the link below and depicts how they would fit together today. They do not completely lock perfectly as their coasts have been eroded.
S America and N America - the panama canal, Europe, Asia, and Africa - the Suez.
No.
Alfred Wegener theorize that all the continents were once joined together in a single landmass and have since drifted apart.
