Hence, the total water area is 361,132,000 square kilometres. The remaining 29.2% of the Earth\’s surface is land consisting of continents and islands. Thus, the total land area is 148,940,000 square kilometres. Every continent has countries, except the Antarctica continent. These countries have their own boundaries.
