Is any ocean freshwater?
Is any ocean freshwater? Many international organisations are working to clean freshwater sources and prevent them from being contaminated so that the world can have access to safe drinking water. There are no freshwater seas or oceans in the world.
Why are oceans salty but not lakes?
This is primarily because rivers continuously receive fresh water from rainfall and melted snow, diluting the salt content. Most lakes are also not salty for similar reasons. They receive freshwater from rivers and precipitation, which dilutes any salts. However, there are exceptions.
