Radiant energy is heat transferred through electromagnetic waves, such as from the sun or a fire. Convection energy is heat transferred through the movement of fluids or gases, such as warm air rising and cool air sinking. They represent different mechanisms of heat transfer.
Whether electrons are shared or transferred between two atoms is determined by the difference in electronegativity between the atoms. If the electronegativity difference is small, electrons are shared covalently, while if the difference is large, electrons are transferred to form an ionic bond.
Energy can be transferred through conduction, where heat is transferred via direct contact between objects. Energy can also be transferred through convection, where heat is carried by a fluid like air or water. Lastly, energy can be transferred through radiation, where electromagnetic waves carry energy from one location to another.
Heat is normally transferred to specific areas by means of a 'heat sink' which is usually made of a material with low resistance and high transfer of heat. An example of this can be seen in most computers, the heat sink collects the heat from the processor, and there is (usually) a fan which is near or on the heatsink to remove it from the heat sink, effectively lowering the temperature of the processor.
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.

Conduction is the transfer of heat through direct contact between particles, while convection is the transfer of heat through the movement of fluids (liquids or gases). Thermal energy refers to the internal energy of an object due to its temperature, which can be transferred through conduction or convection.
One key difference is that in a radiation zone, energy is primarily transferred through electromagnetic radiation, while in a convection zone, energy is transferred through the movement of hot gas or liquid. Radiation zones are generally more stable and characterized by slow energy transfer, while convection zones are more dynamic and turbulent.

Thermal energy that is transferred is known as heat. It can move from one object to another due to a difference in temperature between the two objects. This transfer of heat can occur through conduction, convection, or radiation.
Heat energy is a form of energy that is transferred between objects due to a temperature difference. It can be transferred through conduction, convection, or radiation. Heat energy is responsible for changing the temperature of an object or substance.
The main difference between convection and microwave cooking methods is the way heat is transferred to the food. Convection cooking uses hot air to cook food evenly, while microwave cooking uses electromagnetic waves to heat food quickly from the inside out.
Earth's heat is transferred by convection, which is the movement of heat through a fluid due to differences in temperature. It is also transferred by conduction, which is the direct transfer of heat through a material due to a difference in temperature between two points.

A convection oven moves the air, a microwave does not.
