In materials, conduction primarily occurs through the transfer of energy by free electrons, lattice vibrations (phonons), or through the movement of charged particles (ions) in electrolytes. In metals, free electrons carry electric charge and heat, while in insulators and semiconductors, phonon vibrations play a significant role in conducting heat.
Heat is transferred through conduction by direct contact between particles in a material. The key mechanisms involved in this process include the vibration of atoms and the transfer of kinetic energy from faster-moving particles to slower-moving particles.
Conduction current refers to the flow of electric charge through a conducting material, such as a metal wire, due to the movement of free electrons. It is one of the mechanisms by which electric current is transmitted in a circuit.
Energy can be transferred through mechanisms such as conduction (direct contact), convection (through fluids or gases), and radiation (electromagnetic waves like light). In these processes, energy is passed from one system to another without physical particles being transferred.
conduction - requires direct physical contact between source and sinkconvection - requires a fluid between source and sinkradiation - electromagnetic radiation from source to sink
No, conduction requires physical contact between objects to transfer heat. Without direct contact, conduction cannot occur.
Because both of those mechanisms take place in physical material stuff, of which there isn't any between the sun and the Earth.

There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.

Thermal conductivity is a Physical property
Conduction of energy is a physical change.

1.Conduction or diffusionThe transfer of energy between objects that are in physical contact2.ConvectionThe transfer of energy between an object and its environment, due to fluid motion3.RadiationThe transfer of energy to or from a body by means of the emission or absorption of electromagnetic radiation
Conduction is the term for heat transfer because of direct contact.
