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.

All seas have salt water because they have sand which has salt.
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.
