How the Sun Heats the Earth - Solar Energy and Radiation Explained #3648765 (License: Personal Use)

This educational illustration depicts the Sun emitting visible and infrared radiation toward Earth; upon absorption, the planet re-emits some energy as thermal (infrared) waves, shown by red wavy arrows. The blue atmospheric layer highlights how Earth’s atmosphere interacts with incoming and outgoing radiation. The diagram simplifies key concepts in planetary energy balance and radiative forcing.

Commonly used in K-12 science curricula, environmental education modules, and introductory climate change materials to explain solar energy transfer, the greenhouse effect, and Earth’s energy budget. Matches user intent for visual learning aids on weather, climate, or astronomy topics.
