The answer depends on the context:
Do you want:
frozen water as a percentage of all water on earth?
frozen water as a percentage of all matter on earth?
frozen water as a percentage of all water in the solar system, or beyond?
frozen water as a percentage of all matter in the solar system, or beyond?
There are other possible interpretations.
no
Briefly put, one hundred percent of the water in Mexico is in Mexico.
Well it is about 20 to 30 percent (i answered it)
97% of water on the Earth is salt water, and only 3% is fresh water of which slightly over two thirds is frozen in glaciers and polar ice caps.
They weigh the same
100%
no
A bit less than 2% of the worlds water is frozen. Antarctica accounts for about 80% of the worlds fresh water.
twice as much
Out of all the water on Earth, only 2.75 percent is fresh water, including 2.05 percent frozen in glaciers, 0.68 percent as groundwater and 0.011 percent of it as surface water in lakes and rivers.
Only 2 percent of fresh water is frozen in glaciers.
2.25%
Technically, none of it. The hydrosphere is the liquid water on Earth. The Cryosphere is the ice. However, only 3 percent of the water on Earth is fresh, 97 % is salt water. Of that 3 % frsh water, 85 % is frozen so 85% of 3% of the water is frozen. So, 2.55% of Earths water is frozen.
According to NOAA: "Of the three percent of the water that is not in the ocean, about 69 percent is locked up in glaciers and icecaps. Ninety percent of that frozen water is in Antarctica and about nine percent covers Greenland."
75%
75%
Their is .5% frozen water in the whole world.
