The sun irradiates the Earth by emitting electromagnetic radiation, including visible light, ultraviolet light, and infrared radiation. This radiation travels through space and reaches the Earth's atmosphere. The Earth's atmosphere then absorbs some of this radiation and scatters the rest, allowing only a portion of it to reach the Earth's surface. This energy from the sun is essential for life on Earth as it provides warmth, light, and fuels various processes such as photosynthesis. **
