North America and South America are connected by a strip of land known as the Isthmus of Panama. This land bridge joins the two continents, effectively making them part of the same land mass.
Asia and Europe are part of one huge land mass separated by the Ural Mountains.
Europe and Asia are part of one huge landmass called Eurasia.
The continents that were part of Gondwana land are Australia, Antarctica and South America.
Before the seven continents, the mass of land was called " pangea".
Continental drift is the theory that explains how the Earth's continents have moved over time due to the process of plate tectonics. About 300 million years ago, all the continents were part of a supercontinent called Pangaea. Over time, the movement of tectonic plates has separated and repositioned the continents to their current locations.
All the continents used to be a part of one land mass and separated. This supercontinent was Pangea.
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.
Asia and Europe are part of one huge land mass separated by the Ural Mountains.
Europe and Asia
Europe and Asia are part of one huge landmass called Eurasia.
The Rhine river flows through Europe, which is part of the Eurasian land mass.
The continents that were part of Gondwana land are Australia, Antarctica and South America.
The Earth (land).
Before the seven continents, the mass of land was called " pangea".
The hypothesis that proposed that Earth's continents were once joined in a single land mass is called continental drift. This theory, formulated by Alfred Wegener in the early 20th century, suggested that the continents were once part of a supercontinent called Pangaea that later broke apart and drifted to their current positions.
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.
Antarctica is not different from Earth; Antarctica is part of the Earth, the fifth largest of seven continents that make up the land mass of the planet.
