Introduction:
The Sun is the primary source of energy for the Earth. It emits a wide range of electromagnetic radiation, including X-rays, gamma rays, infrared rays, ultraviolet rays, and visible light. However, the largest amount of energy received by the Earth is in the form of infrared rays and heat.

Explanation:
- X-rays and gamma rays: X-rays and gamma rays are high-energy forms of radiation. While the Sun does emit X-rays and gamma rays, their contribution to the total energy received by the Earth is relatively small. These types of radiation are absorbed by the Earth's atmosphere and do not reach the surface in significant amounts.

- Ultraviolet rays and X-rays: Ultraviolet (UV) rays and X-rays have higher energy than visible light but lower energy than gamma rays. UV rays are responsible for causing sunburns and can be harmful to living organisms. However, the amount of energy received by the Earth in the form of UV rays is also relatively small compared to other forms of radiation.

- Gamma rays and visible rays: Gamma rays are the highest energy form of electromagnetic radiation emitted by the Sun. However, they have very short wavelengths and are mostly absorbed by the Earth's atmosphere. Visible light, which includes the range of colors that human eyes can perceive, is also a form of electromagnetic radiation. While visible light is an important source of energy for the Earth, it is not the largest contributor.

- Infrared rays and heat: Infrared radiation has longer wavelengths than visible light and is not visible to the human eye. It is responsible for the feeling of warmth when exposed to sunlight. Infrared rays and heat account for the largest amount of energy received by the Earth from the Sun. This energy is absorbed by the Earth's atmosphere, land, and oceans, contributing to the overall temperature of the planet.

Conclusion:
Although the Sun emits a range of electromagnetic radiation, including X-rays, gamma rays, ultraviolet rays, visible light, and infrared rays, the largest amount of energy received by the Earth is in the form of infrared rays and heat. This energy is responsible for sustaining life on Earth and maintaining the planet's overall temperature.
