Conduction occurs in solid whereas convection occurs in fluids.
Explanation:
Conduction
1. Conduction is a process of transfer of heat energy by direct contact.
2. It occurs in solids through molecular collisions of matter.
3. Conduction is due to temperature difference in the body.
4. It is a slow process.
5. Conduction process needs matter for heat transfer but does not require bulk motion of matter.
6. The rate of heat transfer in conduction is governed by Fourier's Law of Conduction.
Convection
1. Convection is a process of heat energy transfer by actual motion of matter.
2. It occurs in fluids by actual flow of matter.
3. Convection is due to density difference.
4. Convection is also a slow process.
5. It does not require any bulk transport of matter.
6. The rate of heat transfer is governed by Newton's Law of Cooling.

Conduction:
Heat transfer in the conduction occurs due to movement of molecule or we can say that due to movement of electrons in the two end of same the body. Generally, phenomenon of conduction happens in the case of solid. In conduction heat transfer takes places due to direct contact of two bodies.
Convection:
In convection heat transfer of fluid takes place due to density difference. In simple words we can say that heat transfer occur due to motion of fluid.
