The tributaries carry small amounts of salt into the lake
<u>Explanation</u>:
The Greatest salt lake is one of the most saline inland water body in the world.The water carried to this lake by the tributaries is very less as compared to the amount of the salt present in the lake. Rest part of the salt remains in the lake as such.
When the water from the lake gets evaporated, it leaves behind the salt. When time passes by, or years of inflow and evaporation salts they gets deposited layer over layer. The amount of salt added leads to formation of new minerals on the sea floor.
