Thermal energy reaches Earth's surface primarily through radiation from the sun. The sun emits electromagnetic radiation that travels through space and warms the Earth's surface upon contact. This process is known as solar radiation.
Heat given off by a fire in a fireplace is an example of thermal energy transfer through radiation when the hot objects emit infrared radiation that is absorbed by cooler objects in the room, warming them up.
Thermal energy is transferred on Earth's surface through three main processes: conduction (direct transfer through material contact), convection (transfer through fluid movement), and radiation (transfer through electromagnetic waves). These processes work together to distribute heat and regulate temperature across the surface of the Earth.
Thermal dissipation occurs when the heat energy stored in an object (such as a heated material or component) is transferred to its surroundings, resulting in a decrease in temperature. This transfer of heat can happen through conduction, convection, or radiation, allowing the object to return to thermal equilibrium with its surroundings.
Heat is transferred through the Earth primarily through conduction, where heat is passed from one particle to another. In the Earth's interior, heat is also transferred by convection, where hot material rises and carries heat with it. Additionally, heat can be transferred through radiation, in which energy is emitted as electromagnetic waves.
Thermal energy can be transferred through conduction, convection, or radiation. Conduction is the transfer of heat through direct contact between particles, convection involves the movement of a fluid to transfer heat, and radiation is the transfer of heat through electromagnetic waves.
Heat conduction: the transfer of thermal energy through direct contact between materials. Heat convection: the transfer of thermal energy through the movement of fluids or gases. Heat radiation: the transfer of thermal energy through electromagnetic waves, such as infrared radiation.

Radiation is the fastest method of thermal energy transfer through a vacuum because it does not require a medium for propagation. Radiation can travel through a vacuum at the speed of light.
Thermal energy cannot be transferred through a vacuum via conduction or convection because these methods require a medium. However, thermal energy can be transferred through a vacuum via radiation, as electromagnetic waves can travel through empty space.
Electromagnetic waves transfer thermal energy through radiation. These waves include infrared radiation, which is commonly associated with heat transfer.
The transfer of thermal energy by electromagnetic waves is called thermal radiation. It does not require a medium and can travel through vacuum. Objects that are hot emit thermal radiation in the form of infrared waves.
Radiation
Thermal energy can move through conduction, where heat is transferred through direct contact between objects. It can also move through convection, where heat is transferred through the movement of liquids or gases. Lastly, thermal energy can move through radiation, where heat is transferred through electromagnetic waves.
Thermal energy reaches Earth's surface primarily through radiation from the sun. The sun emits electromagnetic radiation that travels through space and warms the Earth's surface upon contact. This process is known as solar radiation.
Conduction: Thermal energy is transferred through a material without any movement of the material itself. Convection: Thermal energy is carried through fluids (liquids or gases) by the movement of the fluid itself. Radiation: Thermal energy is transferred through electromagnetic waves, such as light or infrared radiation, without the need for a medium.
Thermal energy from the sun reaches the Earth through radiation. The sun emits electromagnetic radiation, including visible light and infrared radiation, which travels through the vacuum of space and heats the Earth's atmosphere and surface upon contact.
