Air is circulated around the earth as it is heated at the equator and cooled at the poles. these air circulation patterns in the atmosphere are known as a. conductive energy b. convection currents c. radioactive waves d. radiant heat

B. Convection Currents
If you want it explained, read on.
Lets go through the answers here. A. Conductive enegry cant be correct since conduction is when heat is transfered through touching objects. B. Convection currents are when heat is trasfered through a current, so we will come back to this one. C, well, its not radioective at all. D radient heat is when heat trasfers from the sun. Now, back to b. The question describes a circular current between the poles and the Equator. Heat tranfer through convection is through currents.
