Where is Earth's saltwater primarily found?

Explanation:
Saltwater is found mainly in the oceans. Oceans hold the vast majority of Earth's water—about 97%—and their salinity is about 35 parts per thousand, giving them the characteristic seawater. The other water bodies—rivers, lakes, and groundwater—are much smaller in total volume and are predominantly freshwater, with salts present only in much lower concentrations. So, when asking where saltwater is primarily found, the oceans are the primary reservoir.
