The first continents formed through a process called plate tectonics, where tectonic plates collided and merged over millions of years. These collisions created mountain ranges and landmasses that eventually evolved into the continents we have today. The process is ongoing, with continents continually shifting and changing position.

Which scientist first proposed the continents were once joined in a single landmass called Pangaea?
Alfred Wegener, a German meteorologist and geophysicist, first proposed the theory of Pangaea in 1912. Wegener suggested that the continents were once connected in a supercontinent that later drifted apart to form the continents we see today.
Why were the first continents made from granite?
The older, basaltic rocks that formed on the Earth before granite first developed were to easily weathered by the ocean to form permanent continents. The ocean floor is made of basalt, but when basaltic formations extended to the surface of early oceans, they were quickly weathered away. Granite first formed when underwater volcanoes erupted, and the magma was cooled extremely quickly, forming a less dense, but much more durable, rock than basalt. These early granite formations served as the "anchors" for the early continents to form upon. In short, granite was the most durable form of rock to develop on early Earth, and, as such, it provided a durable place for the continents to develop on, safe from the erosive forces of the early oceans.
What is the name of the first land mass brfore it broke up into contenents?
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.
What were the continents called when they were together?
When the continents were together in a single landmass, they were known as Pangaea. This supercontinent existed around 300 million years ago and eventually broke apart to form the continents we have today.
How do the continents fit together to form the Earth's landmasses?
The continents fit together like puzzle pieces to form the Earth's landmasses due to the process of plate tectonics. This theory explains how the Earth's outer shell is divided into large, rigid plates that move and interact with each other. Over millions of years, these plates have shifted and collided, causing the continents to drift and eventually come together to form the landmasses we see today.
How did the 7 continents form?
god did on the first day
Can smaller continents form from larger continents by rifting?
No. Its through paleomagnetism.

When plates separate what do they form?
they form the 7 continents in this case.
What three continents came together to form Pangaea?
It wasn't three continents it was all of them.
Which continents form the boundary of the meditarran sea?
The continents that form the boundary of the Mediterranean Sea are Europe to the north, Asia to the east, and Africa to the south.
Why are fossils found in differrent continents?
The Continents were combined to Pangea at first.
What are tectonic plates how were continents formed?
these are the plates under the land and they are spins round and when they meet and they form the continents
What are the continents without water?
Continents are landmasses and by definition have some form of water surrounding them. There are no continents without any water around them.
What were the first 3 continents to separate from the mass of continents?
India, Africa & Texas

Which of the continents form one large landmass?
