What are the major sulfur sinks?

Earth's main sulfur sink is the oceans SO42−, where it is the major oxidizing agent. When SO42− is assimilated by organisms, it is reduced and converted to organic sulfur, which is an essential component of proteins.

Explanation:

Earth's main Sulfur sinks are the oceans of sulfate.

EXPLANATION:

Source means how a substance is released in the atmosphere. Earth's sulfur is mainly stored under the bottom of rocks and also as sulfate salts deep inside oceans. Major sources of sulfur are oceans, pyrite, and gypsum evaporated from seawater.

Also, airborne sea spray and marine coastal organisms are major sources of sulfur in the environment. Sulfur cycle is the system of process by which the sulfur would travel between several rocks, seas and living organisms. These cycle are considered to be more important in the field of biology as they may affects the quality of more minerals found in the earth surface.
