On average, ocean water is about 3.5% salt
solution. This usually depends on latitude,
evaporate rates, and connections to other bodies
of water. The Atlantic Ocean is the saltiest out
of all of the major oceans; its salinity can reach
up to 3.7%. There are other bodies of water that
are much greater in salt concentration than that,
like the Dead Sea (near the Mediterranean) and
Lake Assal (in Africa), which have salt
concentration levels up to 34%. When water is this
salty, you can float very easily in it!
