The sun primarily affects Earth by warming up its surface through the transfer of solar energy in the form of heat and light. This ensures the continued survival of all organisms on the planet.
Sunlight is an important component that drives photosynthesis on Earth. Green plants are able to harness this energy and use it to produce vital food that people consume, including the oxygen that they breathe to sustain life.
The sun's heat warms the oceans and is crucial to the water cycle , which provides essential water for all organisms. Furthermore, the sun heats up Earth's atmosphere, directly influencing the climate and weather patterns people on the planet experience on a daily basis.
