Step-by-step explanation:
1. The sun provides light and heat that sustains life on Earth. Without the sun, the planet would be cold and dark, and life as we know it would not exist.
2. The sun's gravity keeps the planets in our solar system in their orbits. Without the sun's gravitational pull, the planets would either drift off into space or spiral towards the sun, causing catastrophic collisions.
3. The sun's magnetic field also affects Earth, creating the auroras, or northern and southern lights, as charged particles from the sun collide with Earth's atmosphere. However, solar flares and other intense solar activity can also disrupt communication systems and cause other problems for humans on Earth.
