Rocks! -a brief illustrated primer. A superb, richly illustrated, survey from geologictimepics with detailed inks to an extensive gallery of rock types and formations. And,of course, incidentally proof of the absurdity of Young Earth “geology”

Seems like most people I know like rocks. They bring home unusual rocks from vacations; they admire beautiful facing stones on buildings; they frequently ask “What is this rock”? Considering that the type of rock you’re looking at reflects the processes that caused it to form, some basic rock identification skills can go a long way to understanding our planet!
Of course there are thousands of different rock types —But! they ALL fit into one of three categories: igneous, sedimentary, or metamorphic. Here’s a brief, illustrated summary of each.
Igneous rocks are those that form by cooling and crystallization from a molten state. Consequently, they consist of crystals of various minerals that form an interlocking mosaic like the rock in…

Comments I have had from creationists fall into three broad groups (and note that contrary to what Dawkins says, some of these are at least partly informed, highly intelligent, and completely rational):
1) Simple misstatements
2) Appeal to the Bible
3) Purportedly scientific arguments, some without merit, while others refer to important issues.
From simple misstatements, not very much can be learnt, except perhaps the source of the misinformation. Remember that if someone quotes wrong information, the burden of proof is not on you but on them. Leave it there, as in this actual exchange: Read the rest of this entry
