Then, answer the questions. 29. star can be classified based on its I II III temperature brightness size I and II I and III II and III I, II and III 13

14 30. hoose the correct statement related to the phenomena occurring on the surface of the Sun. Sunspots are violent explosions on the surface of the Sun. Solar flares are bright red arches or loops of hot gases projecting from the surface of the Sun. Prominences are dark spots seen on the surface of the Sun. Solar flares are violent explosions on the surface of the Sun 31. How is energy generated by the Sun? Helium atoms undergo nuclear fusion to form hydrogen atoms. Hydrogen atoms react with helium atoms to produce heat and light energy Hydrogen atoms undergo nuclear fusion to form helium atoms and produced large amount of energy. Helium atoms under high temperature in the core of the Sun split up. 32. hoose the correct statement. Galaxies are divided based on their shapes which are spiral, elliptical and irregular. galaxy consists of millions of planets and their moons only. The three types of galaxies are spiral, spherical and irregular. Galaxies are divided based on their sizes. 14
