Detailed explanation-1: -It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
Detailed explanation-2: -It gets as hot as 27 million degrees Fahrenheit in the sun’s core. The energy travels outward through a large area called the convective zone. Then it travels onward to the photosphere, where it emits heat, charged particles, and light.
Detailed explanation-3: -How does the sun’s energy travel to earth? The radiant energy is carried by packets of light called photons. The photons are bundles whose energy depends on frequency. The radiant energy corresponds to a range of wavelengths on the electromagnetic spectrum, of which visible light is only a small portion.
