"Many lines of evidence support a theory that the entire Earth was ice-covered for long periods 600-700 million years ago. Each glacial period lasted for millions of years and ended violently under extreme greenhouse conditions. These climate shocks triggered the evolution of multicellular animal life, and challenge long-held assumptions regarding the limits of global change."
Uh...? What?
Snowball Earth. Evidently, at one point the earth was... a snowball. I have to read a 17 page paper about this theory for my geology class and my teacher expects me to understand it. Natural remnant magnetization? I should be flattered. I mean, she thinks I'm smart enough to understand this and, to be honest, generally I do. I get the concept and what happens-- but there are so many words. I've seen maybe two words with one syllable.
Something I have noticed throughout this paper is that scientists have extremely complicated names. Much too complicated. Kirschvink, Schrag, Mikhail Budyko, Sohl. On a couple of occasions I've mistaken Kirschvink as a scientific term. Imagine my shock and the clarity of this paper when I figured out Kirschvink is a person, not volcanic carbon dioxide emissions.

hehe the earth a snowball?
Anyway, I hope you finish the paper soon. 17 pages sounds like a lot, especially with only a few one- syllable words! :)
Good JOb! :)
