  • Amantle Nyangane Botswana The source of energy occurring on the earth's surface originates from the sun, which radiate solar energy that heat the earth creating air movements in the atmosphere. Note, the sun drives the winds, ocean currents and water cycle.

  • Eddie Akpan United States of America The origination of energy is from the sun, which radiate solar energy that heat the earth creating air movement in the atmosphere. Therefore the sun drives the wind, ocean current and the water cycle that affects matter within the earth.

  • Taylor Jackson United States of America Solar energy heats the earth unevenly, due to this the sun controls wind, rain cycles, and ocean currents.

  • Jafia Noy Other energy on earth is derived from the sun . in the form of radiation . it is responsible for wind ocean temperature and growth of plants in the form of photo synthesis

  • Michal Kmet United Kingdom The Source of energy for us is the Sun. Heating the Earth, influences the water cycle, wind flow etc. and plant use the energy of the Sun in photosynthetic reaction. Sink means the energy lost in an process. Both (sources and energy sink) must me calculated in a business and environmental managing.

  • Susan Hinder United Kingdom Energy sources are abundant on the Earth. All engery initially durive from the sun. Atainable sources of energy include, thermal, fossile fuel, wind and solar power. When an abundance of power if obtain but is lost or used it is called Engery Sinks.

  • Olatomiwa Asaju United Kingdom I really don't understand the process of the sun heating up the earth and resulting into wind and ocean current

    • De Irdre United Kingdom The sun's rays travel space and to the Earth. The sun's rays are full of energy, and this energy heats up whatever the rays touch. When the rays heat up the air on the earth, the hot air rises. As the hot air rises, cold air blows in to take it's place, because cold air is heavier than hot air. This causes wind. As the wind blows over the oceans, they whip up waves which helps create current. The ocean's currents are controlled by a lot of things, including the pull of the moon's gravity on the Earth.
