Answer 2

The Sun is a yellow dwarf star, (C) which means it is a medium-sized star. It is believed to be about 5 billion years old. The Sun spins slowly on its axis (F) as it revolves around the galaxy. The center, or core, of the Sun is very hot. A process called "nuclear fusion" takes place there. Nuclear fusion produces a lot of energy. Some of this energy travels out into space (A) as the solar wind also flows out from the Sun. Some of it arrives at the Earth! Streams of gas particles known (B) as moving particles off the Sun's surface. On the Sun's surface, we can see storms. We call these storms "sunspots" (D) because they look like dark spots on the Sun's surface. The Sun also produces big explosions of energy called solar flares. These flares shoot fast (E) as heat and light. These particles can hit the Earth's atmosphere and cause a glow called an Aurora.
