Convection. This happens in a fluid (gas or liquid), When a mass of fluid is heated it expands and becomes less dense than the unheated fluid round it. This density difference causes it to rise against gravity, bodily moving the whole mass of warm fluid. Obviously convection could not happen where there was no gravity (eg in a spacecraft orbiting Earth).
Conduction. This happens because heat energy causes atoms or molecules to vibrate faster. As they do so they bump into the atom or molecule next to them and cause this to vibrate more. In this way the energy is passed along inside the body of the substance. Obviously this means while convection can not happen in space, conduction and and does.
Convection and conduction are related the vibrational energy of conduction is what causes the fluid to expand, its molecules vibrating harder take up more room.
Also understand that Heat energy is actually a specific form of Kinetic energy - an energy of motion - but happening at the atomic scale.

What is the difference between conduction convection and thermal energy?
Conduction and convection are two ways in which thermal energy is transferred, the third way is by radiation.
What is the difference between conduction and convection?
Conduction transfers heat by direct contact. Convection, is the transfer of heat by movement of the medium, due to difference of density caused by changes in temperature.
How do you explain the difference between conduction convection or radiation can transfer heat explain?
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
What is an energy transfer due to a difference in temperature?
conduction, convection or radiation
What is an energy transfer due to difference in temperature?
conduction, convection or radiation
What is the difference between conduction and convection a 5th grade answer please?
Conduction occurs in solids and liquids but not gases. Convection occurs in gases and liquids.

What does conduction and convection need to work?
Heat energy and a temperature difference.

What is an energy transfer due to difference in temperature?
conduction, convection or radiation
What are the three forms of heat transfer?
convection conduction and radiation
What is the main difference between conduction and convection?
A traditional conduction oven has a heat source at the bottom and bakes from the bottom up. Whereas convection has a fan blower that circulates the heat all around the food cooking much more evenly and faster.
What are the differences between conduction and convection?
Conduction is the transfer of energy by contact while convection is the transfer when liquid particles move in a cyclic manner when it is heated.
What happens at each layer of the earth?
Conduction, Convection, Conduction,Convection, Conduction, Radiation
