Why are there 6 contenents?

Answer 1

There are actually 7 continents not 6.

1. Asia
2. Africa
3. North America
4. South America
5. Antarctica
6. Europe
7. Australia

The earth's crust floats on earth's mantle and the crustal is moved round the planet by convection currents in the mantle.

Sometimes the bits of the crust are brought together into a super continent (this has happened in the past and this continent was called 'Pangaea') and sometimes the crust break up into bits and become separated - this is the condition at present.

Thus the answer to your question is :- there are 7 continents because the mantle convection has broken the crust up into 7 bits at the moment.

Answer 2

There are seven continents on Earth: Africa, Antarctica, Asia, Europe, North America, Australia, and South America. The number of continents is a historical and cultural concept that has evolved over time based on various criteria, such as geographic separation, cultural differences, and tectonic plates. The division of continents is not strictly based on scientific boundaries, leading to variations in the number of continents depending on different perspectives.
