Q:

Why are oceans important?

A:

Quick Answer

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.

Full Answer

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.

    What is a good explanation of the sulfur cycle?

    A:

    The sulfur cycle involves both atmospheric and terrestrial processes with sulfur first being released into the atmosphere and environment by weathering rocks before coming into contact with air and getting converted into sulfate, which is taken up by plants and microorganisms before moving up the food chain. Once organisms expire, they will release the sulfate back into the environment where it will reenter the atmosphere, rain down into the ocean and combine with iron in the water to form ferrous sulfide and finally transform back into marine sediment. Ferrous sulfide is responsible for the black and brown color of marine sediment.

    Why is the sun so important to life on Earth?

    A:

    The sun is important to Earth because it helps regulate the climate, is the main source of energy for producers in the ecosystems and it keeps the oceans from freezing, along with providing light. If just one of these factors changed dramatically, it would impact all life on Earth. Without the sun, the planet's oceans would freeze, temperatures would drop and all life would die off without light or food.

  • Q:

    What produces most of the world's oxygen?

    A:

    Scientists believe phytoplankton in the Earth's oceans produce between 50 and 85 percent of the planet's oxygen. The exact figure is difficult to calculate because scientists do not know how much phytoplankton exists on Earth. Phytoplankton, including algae, make oxygen by photosynthesizing sunlight.

  • Q:

    Where can you find sulfur?

    A:

    Sulfur makes up 3 percent of Earth's crust, and the oceans, air, sulfur hot springs and human digestive system are all sources of sulfur. As of 2014, the petroleum refining industry produces most of the world's supply of sulfur. Petroleum refining produces more sulfur than the market demands.
