Why are the Northern and Southern hemispheres called Land and Water Hemispheres?

The Land and Water bodies are unevenly distributed on Earth’s surface. This can be justified because the Northern hemisphere has 60% of land and 40% of water. Whereas, the Southern hemisphere has 81% of water and 19% of land. Therefore, the Northern hemisphere is known as the ‘Land Hemisphere’ and the Southern hemisphere is known as the ‘Water hemisphere.’
