Convection and conduction are both means of heat transfer involving materials.
Convection usually occurs in liquids and gases. Heated parts of these materials expand and become less dense. Pressure from the cooler, less light parts (due to gravity) pushes the lighter heated parts upwards. Near the surface , these cool, sink and circulate upwards again when heated.
Conduction can occur in all substances but most efficiently in solids like metals where the particles are close together. If the particles in one part vibrate more when heated to a higher temperature, this vibration is passed along through the material. Conduction can occur in any direction but always from the hottest towards the coolest parts.

Compare conduction and convention?
conduction takes place in solids while convection takes place in liquids and gas.
What are the three forms of heat transfer?
convection conduction and radiation
Compare and contrast conduction and convection?
convection means when something is heated it expands or conducts eg. metal is heated it contracts when it is cooled it contracts.
Energy that is transmitted primarily through solids?
Conduction :)
Compare the ways in which conduction and converction transfer heat in the atmosphere?
By definition convection is the direct contact transfer of heat. Convection is the wavy air above car exhaust.

Conduction
What is the differ of conduction and convection?
conduction by itself is slower to heat but conduction and convection is faster to heat
