Why does the earth have 7 continents?

Answer 1

The continents all started as one huge continent named "Pangea". They seperated apart because of erosion. Hope this helps!

Answer 2

The Earth's continents are a result of tectonic plate movements over millions of years, leading to the current configuration of seven main landmasses. These continents have been shaped by geological processes such as continental drift, volcanic activity, and erosion. The number of continents is a human-made concept based on how we divide and categorize the Earth's landmasses.
