5.1.2 Quiz: Energy Bill Match each item with the process that provides its energy. Fossil fuels Sun Hydropower square Water cycle ? square Photosynthesis ? square Nuclear fusion ?

This question is asking to match each energy source with the process that provides its energy. <br /><br />1. Fossil fuels: These are formed from the remains of ancient plants and animals that have been subjected to heat and pressure over millions of years. The energy in fossil fuels comes from the process of nuclear fusion that occurred when these plants and animals were alive. <br /><br />2. Sun: The Sun's energy comes from the process of nuclear fusion. In the core of the Sun, hydrogen atoms combine to form helium, releasing a tremendous amount of energy in the process. This energy is what powers the Sun and provides light and heat to the Earth.<br /><br />3. Hydropower: This is a form of renewable energy that is generated by using the energy of moving water to produce electricity. The energy in hydropower comes from the water cycle, which is the continuous movement of water on, above, and below the surface of the Earth.<br /><br />4. Photosynthesis: This is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigments. The energy for photosynthesis comes from the Sun.
