<span>What a fascinating question! Just out of college, on my first job, I was called to the delivery room to assist the obstetrician in collecting a blood sample from the not-yet born fetus? scalp. I was nearly immobilized at the sight of the impending birth. Ever since that night, I have gotten goosebumps when witnessing a birth. It is certainly an amazing event, and pondering the entire journey from conception to birth is marvelous! Some of the material I have found is published by religious, political and anti-abotion sites. Neither Google Answers nor I endorse any of these sites. Such web pages were cited here for conception and gestation information, and not because of ideology.</span>

These vary greatly every so often on a daily basis. Climate, on the other hand is categories into arctic, subarctic, subterranean, Mediterranean, temperature, equatorial, and etcetera.

These general weather patterns over a region will make up its climate. Climate does not change considerably. Therefore the climate of a region remains steady.
