Where does the salt in oceans come from?

glaciers contain salt and melt into the ocean.
pollution from trucks adds salt into the ocean.
minerals from the land are washed into the ocean.
decomposing fish and plants in the ocean increase salinity.

The correct answer is minerals from the land are washed into the ocean.

Explanation: Rain water is slightly acidic, and as the rain erodes rock, acids in the rainwater break down the rock. This process creates ions, which are carried away in runoff to streams and rivers and eventually to the ocean. Two of the most prevalent ions are sodium and chloride, and when they are together they are salty, creating salt water.
