Where does the salt in the sea come from?

Sources of salt in sea: Know what is the process of salt formation in water –

Minerals from rocks

Salt is created when rocks dissolve in water and release minerals.

Dissolution by rain

Rain dissolves minerals from rocks, which flow into the sea through rivers.

Rivers bring minerals

Rivers are a major source of minerals and salt for the sea.

Salt from vapor

Water from the sea evaporates due to heat, and the salt remains behind.

Deposits on the sea floor

Over time, salt gets deposited on the seabed, forming layers.

Volcanic mineral

Volcanic eruptions release minerals that also contribute to the salt content.

Deposits from the early Earth

The sea has been accumulating salt since the early days of Earth's formation.

Marine life balance

Marine life plays a role in maintaining the salt balance in the sea.

Polar melt salinity

When polar ice melts, it adds more minerals, increasing the salinity.

Winds and rain

Winds and rain also help bring minerals into the sea, affecting its salt content.
