The square of the orbital period of a planet around the sun is proportional to the cube of the planet's orbital radius. this follows the a. law of ellipses b. law of harmonies c. law of kepler

That statement is Kepler's 3rd law of planetary motion.  

It's also often referred to as the "Law of Harmonies".

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

he . if i may ask what i your question exactly?
