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.
What are the two primary sources for the salts in seawater?
Earth's interior
Why will light from two closely spaced stars not produce a steady interference pattern at the earth's surface?
For a steady interference pattern, the two sources of light must be monochromatic and coherent.The light coming from any star contains many wavelengths. Hence, it is not monochromatic.Also, the light is from two different sources. So, the two sources will not be coherent.Because of these reasons, the stars will not produce a stable interference pattern.
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 primary sources for the materials that comprise the dissolved components in seawater?
Chemical weathering and out gassing
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 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."

Where is oxygen obtain?
The two main sources for obtaining oxygen are the air - 23% of air is oxygen - and water by electrolysis.
What are the two sources of energy that heat Earth's surface?
The sun and the earth's core.
Which two gases are exchanged at the surface of airsack?
oxygen + carbon dioxide
What are two main chemical elements found in seawater?
H & O (Hydrogen and oxygen) Exept H & O sea water has Cl & Na ( Clor , Soudeum )
Where can you buy oxygen for a person with a pulmonary decease?
As the physician treating the person wit pulmonary disease where the nearest two or three sources of oxygen can be found.
