What are two major sources of the elements in seawater?
These elements are transported by rivers to the sea. Another source is the volcanic activity.
The two major dissolved gases in ocean water are?
The two major dissolved gases in ocean water are oxygen and carbon dioxide. Oxygen is essential for marine life to respire, while carbon dioxide plays a role in the ocean's carbon cycle and influences seawater acidity levels.
What are the two primary sources for the salts in seawater?
Earth's interior
What are two sources of chemicals that may cause cancer when they enter the body and react with oxygen?
Two sources of chemicals that may cause cancer when they react with oxygen in the body are tobacco smoke and certain industrial pollutants. Tobacco smoke contains various carcinogens that can damage DNA and lead to the development of cancer. Industrial pollutants, such as benzene and asbestos, can also undergo chemical reactions in the body that may result in oxidative stress and DNA damage, leading to the formation of cancerous cells.
What are solutes and what two ions comprise the majority of seawater?
These ions are Na+ and Cl-.
What are two ways that oxygen enters seawater?
Oxygen enters seawater through diffusion from the atmosphere at the water's surface and through photosynthesis carried out by marine plants and phytoplankton.
What are sources of oxygen in ocean water?
Oxygen in ocean water mainly comes from two sources: photosynthesis by marine plants and phytoplankton, and diffusion from the atmosphere at the water's surface. Photosynthesis by marine plants produces oxygen as a byproduct, while surface diffusion replenishes oxygen levels that can be consumed by marine organisms.
What are two primary sources for the materials that comprise the dissolved components in seawater?
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.
What are the two most abundent elements in seawater are?
They are the hydrogen and oxygen of the water itself. After that it's chlorine and sodium.
What two gases are vital to marine life?
Gases are also dissolved by seawater. Carbon dioxide(CO2) is dissolved in ocean water and used by phytoplankton to produce plant matter. Oxygen and nitrogendissolved at the surface from the atmosphere are also present in seawater. Conversely, the ocean also releases these gases into the atmosphere.

Define the term 'available oxygen' as the term is applied to natural sources of fresh water?
"It means the concentration of dissolved oxygen available for fish and other aquatic life. When you discharge untreated sewage into a waterway, the bacteria that break it down use up oxygen and there is less available for other aquatic life. Water at the bottom of deep lakes and deep in the ocean is also low in available oxygen. The two sources of oxygen are contact with the atmosphere at the surface, so atmospheric oxygen dissolves in the surface water, and green algae near the surface."
What are the two primary sources for the materials that comprise the dissolved components in seawater?
Chemical weathering and out gassing
Where is oxygen obtain?
The two main sources for obtaining oxygen are the air - 23% of air is oxygen - and water by electrolysis.
How is Oxygen added to the ocean?
Strangely enough, oceans are oxygen neutral in transferring to / from the air. Oxygen is liberated from water by plankton, and consumed by the various animal cells. There is some minor oxygen exchange with rainfall, wave breaking near shores / shoals, and some carried into the ocean by rivers, etc. Oceans *do*absorb large quantities of carbon dioxide directly from the air... which really hurts the coral reefs.
Which two gases are exchanged at the surface of airsack?
oxygen + carbon dioxide
