What rays does the sun give off and how do they impact the Earth?

The sun gives off three main types of rays: visible light, ultraviolet (UV) light, and infrared radiation. These rays impact the Earth by providing light and heat, supporting photosynthesis in plants, and causing sunburn and skin damage in humans. UV rays can also contribute to the formation of vitamin D in the skin, but overexposure can lead to health risks such as skin cancer.
