Does the earth have 7 continents and will it ever change?

Answer 1

It depends how you count continents, but I could list seven, those being Europe, Asia, Africa, North America, South America, Antarctica, and Australia. However, Europe and Asia are actually part of the same land mass, sometimes called Eurasia, and Australia may be too small to really qualify, so perhaps there are as few as five.

And yes, the number of continents will change. Continents float on the magma of the Earth's mantle, and slowly move, a process which is officially called continental drift. As they move, they will eventually collide, and merge into one giant continent. But that will take an extremely long time.
