Oceans remove carbon from the air, regulate the Earth's climate, provide food, provide jobs and provide oxygen. Oceans are the most valuable shared natural resource on Earth.Know More
Oceans make it possible for people to live on Earth. The oceans are responsible for supplying fresh water to the whole planet by forming the clouds that transport fresh water to land. People use the fresh water to grow food, water livestock and drink. Without fresh water, people could not live.
By absorbing the excess carbon dioxide emissions from human waste and activity, the oceans scrub the atmosphere clean. Ocean plants provide half of the oxygen on Earth.
Fish from the oceans are used for the fish industry and for food. Much of the fisheries' catches are ground into oil and fish meal to feed livestock.
Nearly $130 billion flows into the economy from marine-based jobs every year. Ocean tourism, fishing, recreation, mining ore and oil and biomedical research are some marine-related jobs.
The oceans' water holds heat and carry it across huge basins, where it warms the atmosphere. Evaporation cools the water and warms the air, such as in the tropics. Near the poles, less evaporation takes place and the air is not warmed.Learn more in Geology
Human beings require air because, like all other animals, they are aerobic organisms who require oxygen, which is a component of air. While oxygen is found in water, humans evolved to extract the oxygen from air, as birds, mammals and reptiles do, instead of from the water, as fish and some amphibians do. Additionally, air is necessary to keep the planet warm as it insulates the planet like a blanket.Full Answer >
Air is made up of oxygen, nitrogen and carbon dioxide. It consists of approximately 78 percent nitrogen, 20 percent oxygen and trace amounts of carbon dioxide.Full Answer >
When magnesium burns in air, the oxygen in the air reacts with magnesium metal to produce magnesium oxide. However, for this reaction to occur, heat must be applied. The chemical equation for this reaction is 2Mg + O2 produces 2MgO and energy.Full Answer >
Humans inhale air that is rich in oxygen and exhale air that is rich in carbon dioxide. The pathway that air takes in the human body begins with the nose and ends with the alveoli in the lungs.Full Answer >
