The sun is like a big, bright ball of fire in the sky! 🔥 It's so hot because it's made of something called gas that is always burning and making light and heat. Just like when you sit near a campfire, you feel warm, the sun warms up the whole Earth! 🌎
The sun is very, very far away, but it's still so hot because it's HUGE—much bigger than our planet!
The sun is a giant star made mostly of hydrogen and helium gases. Deep inside it, a special process called nuclear fusion happens. This is when tiny particles smash together and create a lot of heat and light! 🌟
Think of it like millions of tiny fireworks going off all the time! The sun's heat travels through space and reaches Earth, making our planet warm enough for plants, animals, and people to live.
The sun is a massive star powered by nuclear fusion. In its core, hydrogen atoms collide under extreme pressure and temperature, forming helium and releasing enormous amounts of energy in the form of heat and light. This process is similar to how a hydrogen bomb works, but the sun does it continuously for billions of years! 💥
The sun’s heat reaches Earth as radiation (light and infrared waves). Without this energy, Earth would be a frozen, lifeless rock. The sun’s surface (photosphere) is about 5,500°C, but its core is 15 million°C—hot enough to melt anything instantly!
