1.	The predominant gases that. constitute the sun are :1. Hydrogen and Helium2. Hydrogen and Methane3. Methane and Helium4. Methane and CO25.
Answer» Correct Answer - Option 1 : Hydrogen and Helium The correct answer is Hydrogen and Helium. Sun It holds 99.8 percent of the solar system's mass. The visible part of the sun is about 10,000 degrees Fahrenheit (5,500 degrees Celsius), while temperatures in the core reach more than 27 million F (15 million C), driven by nuclear reactions. It is composed of layers made up almost entirely of hydrogen and helium. Hydrogen atoms are compressed and fuse together, creating helium. This process is called nuclear fusion. As the gases heat up, atoms break apart into charged particles, turning the gas into plasma. A very small percentage (1.69 percent) of the sun’s mass is made up of other gases and metals: iron, nickel, oxygen, silicon, sulfur, magnesium, carbon, etc. While Earth orbits the sun, the planet is simultaneously spinning on an imaginary line called an axis that runs from the North Pole to the South Pole. It takes Earth 23.934 hours to complete a rotation on its axis and 365.26 days to complete an orbit around the sun.
