The continent that has the least water is Antarctica as almost all water in Antarctica turns into ice and it's also very dry as it does not get much precipitation.

The continent that has the most salt water is Asia and Africa.

Europe, Balkan Peninsula, Eastern Europe, Anatolia and Caucasus also have a lot of salt water.

The country that has the most underground water is the United States.

The United States has the largest amount of renewable groundwater resources worldwide with an estimated 1,383 billion cubic meters.

70% of Earth's freshwater is located in the Antarctic Ice Sheet and 90 percent of it is ice.

The majority (over 68%) of Earth's freshwater is found in icecaps and glaciers, and just over 30% is found in groundwater.

Freshwater accounts for only a few percent of the total water within the hydrosphere.

Of this tiny percentage, the bulk, about two-thirds, is frozen in glaciers and ice caps.

The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometers and an average thickness of over 2 kilometers.

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet).

The ocean would cover all the coastal cities. And land area would shrink significantly.

But many cities, such as Denver, would survive.

Antarctica is losing ice mass (melting) at an average rate of about 150 billion tons per year, and Greenland is losing about 270 billion tons per year, adding to sea level rise.

At its thickest point the ice sheet is 4,776 meters deep.

It averages 2,160 meters thick, making Antarctica the highest continent.

This ice is 90 percent of all the world's ice and 70 percent of all the world's fresh water.
