Strata is now known to form rapidly from pyroclastic flows.
 * This seems like a rather bold statement. Many strata have fossils in them.  Wouldn't a pyroclastic flow burn the plants and animals to a crisp before they fossilized?  Ungtss 16:32, 23 December 2005 (GMT)

"Strata" is just another way of saying layered rock. --Chris Ashcraft 16:49, 23 December 2005 (GMT)


 * absolutely:). But the sentence says, in essence, "all strata is known to form rapidly from pyroclasic flows."  I have a difficult time believing that all strata were laid down by pyroclastic flow: pyroclastic flows are hot, and would have burned the animals up before they fossilized, wouldn't they?  Certainly some strata may have been formed by pyroclastic flows, but not those with fossils ... Ungtss 16:57, 23 December 2005 (GMT)

Of course there are many kinds of strata unrelated to pyroclastic flows, but all pyroclastic flows produce strata. Your change negated this absolute. You are simply reading-in the "all". It doesnt say that. --Chris Ashcraft 02:05, 24 December 2005 (GMT)
 * Thanks for clarifying. I cleared up the ambiguity.  Ungtss 02:23, 24 December 2005 (GMT)
