Earth receives two crucial kinds of solar radiation:
 |
Light drives photosynthesis, the foundation of food energy. |
• |
Light arrives in quantum packets called photons |
• |
Plants, algae, and archaea and cyanobacteria transform sun-energy into packaged food. |
|
Plant-packaged sun energy transfers from life to life |
| |
|
|
|
Solar Heat drives the water cycle, the winds, the ocean currents |
• |
Heat arrives as infra-red waves |
| |
• |
Earth is at just the right distance from Sol to receive the amount of heat that earthlife needs. |
