Within the photic zone, photosynthesis absorbs carbon dioxide and releases oxygen. At all depths of the ocean, cellular respiration releases carbon dioxide.
Dissolved solids in seawater come from various sources, including weathering of rocks on land, volcanic activity, and underwater hydrothermal vents. Additionally, runoff from rivers, atmospheric deposition, and biological processes like the excretion of marine organisms also contribute to the presence of dissolved solids in seawater.
The dissolved materials in seawater are thought to originate from the weathering of rocks on land, as well as from volcanic activity and chemical reactions at hydrothermal vents on the ocean floor. These processes contribute minerals, salts, and organic matter to the water, creating the diverse composition of seawater.
The most negatively charged ion dissolved in seawater is chloride. In fact, Cl- makes up 55 percent of the seawater's salinity.
The dissolved materials in seawater originate from various sources such as weathering of rocks on the Earth's surface, volcanic activity, and chemical reactions between water and minerals. These processes release ions and compounds into water that eventually flow into the oceans.
The proportion of dissolved salts in seawater has remained relatively stable over millions of years. It is primarily maintained through a balance of inputs from sources like rivers and outputs through processes like evaporation.

The second source of elements found in seawater is from the Earth's interior. Through volcanic eruptions, large quantities of water vapor and other gases have been emitted during ,uch of geologic time. This process is called OUTGASSING

Seawater is a mixture. It is composed of water, various dissolved salts and minerals, gases, and organic matter. These components can be physically separated through processes such as evaporation or filtration.

Dissolved salts are transported by the rivers.

The total dissolved solids (TDS) in seawater typically range from 33,000 to 37,000 parts per million (ppm). This measurement includes salts, minerals, and other dissolved substances present in seawater.
On average, seawater contains about 35 grams of dissolved substances per 1,000 grams of water.
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
