Sentences with phrase «ocean chemistry»
"Ocean chemistry" refers to the scientific study of the chemical components and processes that occur in the Earth's oceans. It involves examining the different substances present in the water, such as salt, minerals, and gases, and understanding how they interact, change, and affect marine life. Full definition
