Although more than 80% of the water vapor in the air has been evaporated from the ocean, water vapor is not salty as the ocean is. Why not?
When water is evaporated from the ocean, most of the minerals dissolved in the water remain behind.
How does the ocean moderate the climate of the earth?
The temperature of the ocean does not change as quickly as that of land. Therefore the ocean warms the land in the winter and cools it in the summer.
