Sea water is a mixture of many different chemical compounds and molecules.
this includes, but is not limited to, water (H2O), table salt (NaCl), dissolved oxygen (O2), Sulfur, Iodine, etc.
if you mean to ask what are the two elements that give "water", then hydrogen and oxygen (as per H2O above)
if you mean to ask what are the two major components of sea water, i would be inclined to answer water (H2O) and sodium chloride (NaCl, existing as dissociated ions within the water).
Sodium chloride, potassium chloride, magnesium chloride
Two sources of oxygen in seawater at the surface include atmospheric exchange, where oxygen from the air dissolves into the water, and photosynthesis by marine plants and phytoplankton, which produce oxygen as a byproduct.
These elements are transported by rivers to the sea. Another source is the volcanic activity.
The two main salts found in ocean salt water are sodium chloride (table salt) and magnesium chloride. These salts make up the majority of the dissolved solids in seawater.
The two different types of source are primary and secondary sources. Primary sources provide first-hand information, like original research or documents. Secondary sources analyze or interpret primary sources and provide commentary or analysis.
The two primary sources for dissolved components in seawater are weathering of rocks on land, which releases minerals into rivers and eventually the ocean, and gases released by volcanic activity. These sources contribute ions like sodium, chloride, calcium, and magnesium to seawater.
Chlorides salts of Na, Mg, Ca.
Sodium chloride, potassium chloride, magnesium chloride
Primary sources and secondary sources. Primary sources are firsthand accounts or direct evidence of an event, while secondary sources are interpretations, analysis, or commentary on primary sources.

The cause is the irrational use of fertilizers.
primary sources and secondary sources.
1. The most important part of the sodium and chlorine are dissolved from the earth salts and transported by rivers in seas/oceans.2. A small part of chlorine is originated from the eruptions of submarine volcanoes
Chemical weathering and out gassing
Two processes are: >regular dissolving of mineral salts from the surroundings >more and more animals decafcdsafying in the sea.ghgd
The two classifications of historical sources are primary sources and secondary sources. Primary sources are original, first-hand accounts of an event or topic, while secondary sources are interpretations or analyses of primary sources created by someone not directly involved in the event.
