ABSTRACT
Seawater is water from a sea or ocean. Everything soluble, given enough time, eventually ends up in the sea.
The rivers of the world dump billions of tons of dissolved and particulate minerals into the oceans each year and have for eons. Undersea volcanoes, hot springs, and volcanic eruptions on land have also added billions of tons of elements. More importantly, 90% of all volcanic activities on Earth occur in the oceans. Additionally, seawater is a biological soup of active organic substances.
