Why are tropical air masses warmer than cold air masses? What region is responsible for warm, humid weather at times during the summer in the Central Plains states?

What region is responsible for cool, humid weather at times during winter for eastern states?

What region is responsible for hot, dry weather during the summer in the desert southwest?

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
