Pangea
Scientists called the now separated land mass "Pangaea."
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.
The name of the land mass made of all of the continents is Pangaea. It was a supercontinent that existed about 300 million years ago before it broke apart into the continents we know today.
The first land mass before it broke up into continents is called Pangaea. It was a supercontinent that existed about 335 million years ago and eventually split apart to form the continents we know today.
The vast majority of the land mass and vegetation on Earth is concentrated in the continents, with the largest land mass being in Asia and the highest vegetation cover in tropical regions like the Amazon rainforest and the Congo basin. Oceans and polar regions make up a significant portion of the Earth's surface, but they have less land and vegetation compared to the continents.

What is the continents of asia are really parts of the same land mass?
Antarctica has the least land mass of all the continents.
All the continents used to be a part of one land mass and separated. This supercontinent was Pangea.
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.
The land mass was called Pangaea before the continents split into the continents we know today. Pangaea was a supercontinent that existed about 335 million years ago.
Asia is the biggest in land mass.
The name of the land mass made of all of the continents is Pangaea. It was a supercontinent that existed about 300 million years ago before it broke apart into the continents we know today.
The inference is that both continents were once one single land-mass.
Europe and Asia
Asia and Africa.
The continents from largest to smallest in terms of land mass are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
