Conduction requires contact, radiation does not.
Radiation in regards to thermodynamics is the straight line (line of sight) transfer of heat from a hot body to a cold body with no intervening fluid to convey that heat. Example: a flame will heat an object some distance from it by radiation as long as the transfer of heat is unobstructed. Place an object between the two and this flow of heat will stop.
Conduction is the flow of heat between a hot body to a cold body by direct contact. Separate the two bodies and this flow of heat stops.
Note: transfer of heat by an intervening fluid is convection. The hot body heats the fluid, then the fluid heats the cold body. All three forms of heat transfer occur in most practical heating applications.

What are the three major mechanism of heat transfer?
The three major mechanisms of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between materials. Convection is the transfer of heat through the movement of fluids. Radiation is the transfer of heat through electromagnetic waves.
What are the three major modes of heat transfer?
The three major modes of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through a material by direct contact of particles. Convection involves the movement of fluids or gases to transfer heat. Radiation is the transfer of heat through electromagnetic waves.
What are the three major ways of heat transfer?
The three major ways of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of materials, convection is the transfer of heat through movement of fluids (liquids or gases), and radiation is the transfer of heat through electromagnetic waves.
What is the major direct source of heat in the troposphere?
The major direct source of heat in the troposphere is the sun. Solar radiation warms the Earth's surface, which then heats the air above it through conduction, convection, and radiation. This process creates temperature variations that drive weather patterns and atmospheric circulation.
