Briefly describe how the Sun produces energy.
The Sun produces energy by the process of nuclear fusion. Nuclear fusion occurs when lighter nuclei combine to produce a larger, heavier nucleus. In the process, energy is released. Nuclear fusion requires very high temperatures and pressures. Nuclear fusion occurs in the core of the Sun when hydrogen atoms combine to form helium atoms.
Which of the following did you include in your answer? Check all that apply.
Describe the differences between sunspots and solar flares.
Sunspots are dark areas on the surface of the Sun that are cooler than surrounding areas. They appear in groups, vary in size, and cycle in number over an 11-year period. Solar flares are sudden eruptions of energy from a small area of the Sun's surface. They are extremely hot (10 to 20 million degrees Celsius) and extend into the corona. Solar flares occur near sunspots and can disturb radio communications on Earth.
