The sun is important to Earth because it warms the seas, generates weather patterns, stirs the atmosphere and provides energy to growing plants. The plants are responsible for providing oxygen and food for life to exist on Earth, according to the U.S. National Aeronautics and Space Administration.
The sun is more commonly known for giving warmth, light and energy, but other aspects of the Sun affect the Earth as well, according to NASA. X-rays and energetic types of atomic particles caused from disturbances and solar flares affecting the sun can also affect radio waves traveling Earth's ionosphere. These disturbances have been known to cause voltage fluctuations and blackouts of cities.
