How Seawater Becomes Salty

General Statement:

Two-thirds of the Earth’s surface is covered in water, and 97% of that is salty seawater. Only 3% of our planet’s water is fresh such as water in rivers, lake, and streams. This fresh water plays a big role in explaining how the sea becomes salty. Water moves around our planet in a cycle powered by the sun: from the sea, to the sky, to the land and then back to the sea.

Explanation:

When the sun heats the water in the sea, it changes into gas called water vapour and rises into the air, through a process called evaporation. After that, the water vapour turns back into liquid water while floating in the air, forming clouds through a process called condensation. Then this water eventually falls from the clouds in the sky as rain, sleet, hail or snow in which the process is also called precipitation. When these flows into streams and rivers, and eventually makes its way back to the sea.

Furthermore, the rain that falls from the sky contains small amounts of chemicals called carbon dioxide and sulphur dioxide which makes the rain slightly acidic. This acid can absorb small amounts of mineral salts, including sodium and chloride. These mineral salts are dissolved from the rocks which then enter the water.

Conclusion:

Thus, the main salt in seawater is sodium chloride. The rain water flows off the land and into the rivers and streams that lead all the way to the sea, carrying the dissolved salts along with it that makes the seawater salty.
