How does heat from the sun reach Earth?

Explanation:
Energy from the Sun reaches Earth mainly through radiation. Radiation is energy transfer that happens with electromagnetic waves traveling through space, which can occur in a vacuum. Space has no air or matter for conduction or convection to work, so those methods can’t move heat from the Sun to Earth across the void. The Sun emits light and other wavelengths that travel across space and are absorbed by Earth’s atmosphere and surface, warming the planet. Some sunlight is reflected back into space by clouds and surfaces, but the process that delivers heat from the Sun to Earth is radiation.
