Solar Radiation | Around 100 trillion Watts or solar energy (light and infra-red rays) hit the Earth. That is around 1.3 kW/m2. |
Cosmic Radiation | These are high energy sub-atomic particles. Small in overall bulk that may affect Earth such as triggering lightning. |
Comet hits | These rarely happen now, but have occurred in the distant past. This must have been where most of our water came from originally. |
Dust hitting Earth | This could be as low as 5 tonnes per day, but could be several hundred tonnes. We don't know. |
Heat Leakage | Heat as infra-red rays. |
