It's part of proper sterile procedures as a precaution against contamination of the media by microorganisms that have attached to the edge of the petri dishes since the last sterilization.

Why must warm agar be cooled down at 45 47 celsius before agar plates are poured?
Why we cool agar before pouring depends on WHY we are pouring it. If we are pouring a gel or standard media for streak culture then we allow some cooling to take place because we don't want to burn our fingers. If we are pouring a pour plate we allow a lot of cooling to take place so we don't kill our microbes through heat steralization. As my teacher used to say "boiled bugs don't grow".
How does the bacteria remain uncontaminated when the covers slightly ajar after pouring nutrient agar into petri dishes?
This may be a better way to ask this... When pouring Nutrient agar into Petri plates, the procedure instructs you to keep the covers slightly ajar. Explain why the plates don't get contaminated from organisms suspended in the air?
What might the consequence be of pouring the plates 2mm deep instead of 4mm?
The depth is important because of the effect it has upon the diffusion. Thick agar slows the lateral diffusion and thus produces smaller zones than than plates held to the 4 mm standard.

Why does one temper agar?
It allows the agar to cool, if the agar is too hot it could kill the bacteria if you are pouring it right onto a sample, if you are pouring it into plates to use later it just makes it easier to pour as you will not be burning your hand off

How old are the Mormon plates?
I assume you are asking about the plates which were translated by Joseph Smith into the Book of Mormon? Those plates were a compilation of four groups of plates - the small and large plates of Nephi, the plates of Mormon, the plates of Ether, and the plates of Brass. The plates of Nephi were written between 580 BC and 321 AD. The plates of Mormon were written between 355 and 421 AD. The plates of Ether were written between 2200 and 300 BC. The plates of Brass were written before the time of the Book of Mormon and contained the writings of Moses, Isaiah, and other Old Testament prophets. Therefore they are from before 600 BC. As Joseph Smith returned the plates to the Angel Moroni following the translation, the actual plates are not in existence on the earth and therefore their ages cannot be determined by scientific means.
