Because 80% of the earth is covered in water. It is estmated that only 7 % of the earth is livable.
Roughly 29% of the Earth's total land surface is considered habitable, meaning it provides suitable conditions for human settlement and support for various ecosystems. This habitable land includes areas such as fertile plains, forests, valleys, and coastal regions where human populations have been able to thrive.
99% of the worlds LANDsurface is covered by the continents
Groundwater makes up about 0.6% of the Earth's total water volume.
The Mantle takes up 84% of the Earth's mass.

The UK covers approximately 0.2% of the Earth's total surface area.
The Mantle takes up 84% of the Earth's mass.
The mantle and core make up the most percentage of Earth's mass. The mantle is the thickest layer and accounts for about 84% of Earth's total volume, while the core makes up about 32.5% of Earth's total mass.
Asia takes up 8.6% of Earth's total land area.
The volume of nitrogen in Earth's atmosphere is approximately 78% of the total volume at sea level, which is roughly 78.08%. The volume of nitrogen is expressed as a percentage of the total volume of gases in the atmosphere.
Portion/Percentage = Total/100 So Total = 100*Portion/Percentage.
Divide the number of interest by the total and multiply the result by 100. That is the percentage of the total.
