Europe and Asia.
yes
Asia and Europe are on the same land mass. That is the correct answer but Technically North and South America share it too.
Wegener discovered that fossils in the west of Africa and the east of South America were exactly the same, and the only way of them being so was that the two continents were originally parts of the same land mass, which he named Pangaea. He also found the same with rock types in all continental plates, and he noticed that all continents fit together like a jigsaw. I learnt that on Thursday in science!
Europe, Asia, and Africa are all on the same continental land mass, but they are split apart politically.
The existence in the fossil record of the same land species on several continents. Since these animals are not seafaring then the continents must have been connected at one time. Also continental drift is supported by vast empirical evidence.
Europe and Asia
Europe and Asia share the same landmass, known as Eurasia. The two continents are traditionally divided by the Ural Mountains in Russia, although the distinction between Europe and Asia is considered somewhat arbitrary.
Asia and Europe share the same land mass with the boundary defined by the Ural Mountains in Russia. This region is known as Eurasia.
What is the continents of asia are really parts of the same land mass?
Asia and Europe both share the same land mass.
There are three continents that span the Eastern and Western Hemispheres: Europe, Africa, and Antarctica.
The inference is that both continents were once one single land-mass.
Asia and Europe and north and south America
Some people are trying to make it so that its one continent called Eurasia. But that's a good question.
Eurasia
Europe and Asia are visibly on the same land mass. Africa is too a part of this land mass. The three continents form the supercontinent of Afro-Eurasia.
North and South America are not located on the same land mass as Asia and Europe are. However, North and South America are located on the same land mass as each other, just as Europe and Asia are.
