Thermal energy can be converted into radiant energy through a process called thermal radiation. When an object's temperature increases, it emits electromagnetic radiation in the form of visible light, infrared, or ultraviolet radiation. This conversion is based on the object's temperature and its emissivity properties.
When radiation is absorbed in a material, the thermal energy of the material increases due to the conversion of radiation energy into heat. This increase in thermal energy can lead to a rise in the temperature of the material.
Sunlight being absorbed by the Earth's atmosphere. X-rays being absorbed by bones during medical imaging. Microwaves being absorbed by food to heat it. Radio waves being absorbed by antennas in a communication system. Ultraviolet radiation being absorbed by sunscreen on the skin. Gamma rays being absorbed by lead shielding in medical facilities. Infrared radiation being absorbed by objects to produce heat. Visible light being absorbed by plants during photosynthesis. Thermal radiation being absorbed by clothing to keep warm. Cosmic radiation being absorbed by the Earth's magnetic field.
All objects emit thermal radiation because they have a temperature above absolute zero. This thermal radiation is a form of electromagnetic radiation that includes visible light, infrared, and ultraviolet rays. The intensity and wavelengths of the radiation emitted depend on the temperature of the object.
Materials on Earth typically absorb shorter wavelengths of electromagnetic energy compared to the wavelengths they radiate. This is because materials absorb higher energy radiation (such as ultraviolet or visible light) and emit lower energy radiation (such as infrared or thermal radiation).

Some is absorbed by molecules in the atmosphere (such as ultraviolet absorption by ozone), some is absorbed on the surface, and some is reflected by clouds or the surface back into space. The surface will re-radiate much of the absorbed solar radiation as infrared (thermal) radiation, and some of this is then absorbed by atmospheric gases such as carbon dioxide and methane.
They technically are not "hot" per se....they are forms of radiation.

Thermal energy is transferred by radiation through electromagnetic waves emitted by a warmer object and absorbed by a cooler one. Unlike conduction or convection, radiation does not require a medium to transfer heat and can occur in a vacuum. The amount of thermal energy transferred by radiation depends on the temperature of the objects and their surface properties.
The main difference between infrared and ultraviolet radiation lies in their wavelengths. Infrared radiation has longer wavelengths than visible light, making it thermal radiation that we feel as heat. Ultraviolet radiation has shorter wavelengths than visible light and can cause sunburn and skin damage.
Ozone is the gas in the atmosphere that greatly reduces the amount of ultraviolet radiation hitting the Earth's surface. The ozone layer acts as a shield, absorbing most of the harmful UV radiation before it reaches the surface.
Most of the solar radiation absorbed by Earth's surface is later radiated back into space as infrared radiation. This process helps to maintain Earth's energy balance and regulate its temperature.
The heat from the sun is in the form of thermal radiation, which includes a spectrum of electromagnetic waves such as infrared, visible light, and ultraviolet radiation. This radiation travels through space and reaches Earth, warming its surface and supporting life.
