Can cause a decrease in temperature;
photosynthesis; the breakdown of water by
electrolysis

Tropical easterlies is mostly likely your answer correct me if i’m wrong

Ithink ahopefully im correct 

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:

The correct answer is:   [a]:   "polar easterlies move cool air to the mid-latitudes."
