Hi jar. I wanted to take this "class" with you---as I never understood Geology that well. Maybe I can learn something along the way. I was curious as to your question regarding sedimentary rocks.
I started reading this article on Sedimentary Rocks from a Tulane University Geology Teacher, but I have never studied Geology before so I wanted some of our EvC folks to help explain it to me better.
Chance as a real force is a myth. It has no basis in reality and no place in scientific inquiry. For science and philosophy to continue to advance in knowledge, chance must be demythologized once and for all. –RC Sproul "A lie can travel half way around the world while the truth is putting on its shoes." –Mark Twain " ~"If that's not sufficient for you go soak your head."~Faith
