What is the difference between conduction and convection?

Conduction is when heat is transfered between two objects directly in contact with one another (like a pot on a stove).
Convection is when heat is transfered by movement of the heated substance such as by currents in a fluid.
Hope this helps!

Conduction and convection are means of transferring heat, the important difference is the medium through which the heat travels. Conduction occurs when heat is transferred through solid objects, like a bar.
