Sources of salt in sea: Know what is the process of salt formation in water –
Salt is created when rocks dissolve in water and release minerals.
Rain dissolves minerals from rocks, which flow into the sea through rivers.
Rivers are a major source of minerals and salt for the sea.
Water from the sea evaporates due to heat, and the salt remains behind.
Over time, salt gets deposited on the seabed, forming layers.
Volcanic eruptions release minerals that also contribute to the salt content.
The sea has been accumulating salt since the early days of Earth's formation.
Marine life plays a role in maintaining the salt balance in the sea.
When polar ice melts, it adds more minerals, increasing the salinity.
Winds and rain also help bring minerals into the sea, affecting its salt content.
