Effects of The Sun on The Earth

Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun gives energy to the growing green plants that provide the food and oxygen for life on Earth. Energetic atomic particles and X-rays from solar flares and other disturbances on the Sun often affect radio waves traveling the Earth's ionosphere, causing interference and even blackouts of long-distance radio communications.

Can you give an another example for the effect of Sun to us?
