☀️ The Sun and Its Energy
This quiz explores the structure, composition, and role of the Sun in our solar system. From its powerful core to the light and heat that reach Earth, you'll discover how this massive star powers all life on our planet through nuclear fusion. **What you'll learn:** - The Sun's internal structure and layers - How nuclear fusion produces the Sun's energy - The Sun's composition and physical properties - Why the Sun is Earth's primary energy source - The path light and heat take from the Sun to Earth
