Geology! I thought you might pick something I didn't know that much about
Ok here is what my mentor has to say about varves.
7. Varves are extremely thin layers (typically 0.004 inch or 0.1 mm), which evolutionists claim are laid down annually in lakes. By counting varves, evolutionists believe that time can be measured. The Green River Formation of Wyoming, Colorado, and Utah, a classic varve region, contains billions of flattened, paper-thin, fossilized fish; thousands were buried and fossilized in the act of swallowing other fish. [See Figure 7 on page 11.] Obviously, burial was sudden. Fish, lying on the bottom of a lake for years, would decay or disintegrate long before enough varves could bury them. (Besides, dead fish typically float, deteriorate, and then sink.) Most fish fossilized in varves show exquisite detail and are pressed to the thinness of a piece of paper, as if they had been compressed in a collapsing liquefaction lens.
Also, varves are too uniform, show almost no erosion, and are deposited over wider areas than where streams enter lakes—where most lake deposits occur. Liquefaction best explains these varves.
PREDICTION 10: Corings taken anywhere in the bottom of any large lake will not show laminations as thin, parallel, and extensive as the varves of the 42,000-square-mile Green River Formation, perhaps the world’s best known varve region.
Now I am sure your next question will probably be what is liquefaction and how does it create varves.
SUMMARY: Liquefaction—associated with quicksand, earthquakes, and wave action—played a major role in rapidly sorting sediments, plants, and animals during the flood. Indeed, the worldwide presence of sorted fossils and sedimentary layers shows that a gigantic global flood occurred. Massive liquefaction also left other diagnostic features such as cross-bedded sandstone, plumes, mounds, and fossilized footprints.
Sedimentary rocks are distinguished by sharply-defined layers, called strata. Fossils almost always lie within such layers. Fossils and strata, seen globally, have many unusual characteristics. A little-known and poorly-understood phenomenon called liquefaction (lik-wuh-FAK-shun) explains these characteristics. It also explains why we do not see fossils and strata forming on a large scale today.
Now for me to explain this whole process on this thread would take up way too much space and I couldn't present the pictures to illustrate the experiments on this so i will give you the link to this chapter which will of course link you to the whole book.This may not convince you but of course it has me.By the way is your father a christian or just a deist/creationist of another sort?
Here is the link to a much better explanation of liquefaction then i could give from sheer memory.Meet my young earth guru walt brown.
