The majority of water in the water cycle is stored in the world's oceans. Oceans hold about 97% of Earth's water. Groundwater, ice caps and glaciers, lakes, and rivers also store water in smaller amounts.
Roughly 97.5% of the world's water is not potable as it is found in oceans and seas (saltwater). This leaves only about 2.5% as freshwater, with the majority of that being stored in glaciers and ice caps.
About 97% of Earth's water is salt water in oceans and seas, while about 3% is fresh water. Of this fresh water, the majority is stored in glaciers and ice caps, as well as underground. Only a small percentage, around 0.3%, is found in surface water sources like rivers and lakes.

About 97% of the Earth's water is saltwater in oceans and seas, with only 3% being freshwater. Of that freshwater, the majority is stored in glaciers and ice caps, with a smaller fraction found in lakes, rivers, and underground aquifers. Overall, the total volume of water on Earth is estimated to be about 1.386 billion cubic kilometers.
All seas have salt water because they have sand which has salt.
