Some creationist arguments I do disagree with

Architect-426, who occasionally posts at EvC, believes that volcanoes played a much bigger role in the history of the earth than is normally recognized, specifically related to the worldwide Flood, and that the theory of plate tectonics is simply wrong. In a brief exchange I had with him I did find out that there has been a great deal more volcanic activity on this planet than I had any idea, so he could be right about volcanism as an unsung major player, but plate tectonics is just too reasonable an idea to dismiss and I don't know how he got so convinced it's wrong. He's been arguing along on this point on this thread at EvC for some time now:

Architect-426 says: Since the (nil) velocity of "plates" truly cannot even be defined as velocity per se, much less translated into energy to "build" anything, then indeed plate tectonics is false in terms of creating geological features.

Thus my entire argument regarding vertical tectonics and volcanism vs. "plate" tectonics, or the idea that land masses move with enough horizontal speed and "crash" into another landmass. This alleged plate tectonic notion is sheer nonsense as shperical mechanics and displacement completely negate this "lateral" type of motion, and is only supported by colorful diagrams to "explain" how this supposedly happens.

Yet the fact remains; no velocity = no energy = no "plate" tectonic construction.

Floodists believe that the separating of the continents by plate movement started out rapid and then slowed down. The movement wasn't always so slow.

But also it seems that even very slow movement of such huge bodies would have quite a bit of crunching force when they impact another body, slow but devastating.

However, a rapid splitting of the continents would generate enough friction or resistance to push up the strata into high mountains at some distance from the exerted force -- Rocky Mountains, Alps -- but more gently buckle the land at the edge of the split -- Appalachians. Architect wants to attribute all mountain-building to volcanism, but I don't see it myself -- the way some mountains are formed, the way the strata were pushed up or buckled, is consistent with the kind of lateral force tectonic movement would exert.

Coyote isn't helping matters in this discussion:

You seem to be trying to force reality to fit within your religious beliefs. Problem is, it doesn't fit. Your religious beliefs are flatly contradicted by reality.

The earth is old, giving the small annual movement of the plates plenty of time to do all sorts of things. You may not like it, but that's the way it is.

I don't think it's Architect's religious position that has him rejecting plate tectonics, it's just the way it looks to him for whatever reason -- based on his experience of the engineering tasks necessary to architecture. That is, it's a scientific position he's taken although one with little credibility it seems to me.

But an old earth isn't necessary. Plate movement fits just fine into the Flood scenario and the Young Earth scenario, does not require an old earth at all. The separating of the continents had to be faster at first and slow down over time of course and some argue that's impossible, but that's all speculation on their part. There's enough evidence for the Flood anyway and tectonic movement explains what happened to the strata AFTER they were all laid down in the Flood. We see them buckled and upended and twisted and split into canyons all over the world. The Flood laid down the strata, then disturbances of the earth such as earthquakes -- caused by tectonic movement anyway -- account for the distortion of the strata. So many Floodists believe that the continents split after the Flood because of forces released in the Flood, and have been moving apart ever since.
