Metamorphic rocks takes from as much as thousands of years to just a few minutes to form depending on the type of metamorphism involved and the range of existing physical properties like temperature and pressure involved.
10,000,000+ years

From bare rock... I think 80yrs.
around 5 hours
It varies with the type of rock being formed. Some igneous rock is formed in a matter of minutes; some sedimentary rock is formed in processes requiring many millions of years.
The time it takes for a thick layer of sedimentary rock to form can vary significantly depending on various factors, such as the depositional environment, the rate of sedimentation, and the type of sediment being deposited. In general, it can take anywhere from a few hundred to millions of years for a thick layer of sedimentary rock to form.
The process of a rock changing into another form can take millions to billions of years, depending on the factors involved such as heat, pressure, and chemical reactions. This transformation is part of the rock cycle, where rocks can change from one type to another over geologic timescales.
No one really know what rock came first but I would assume it would be Igneous because it came from volcanoes and those have been around a long time. Sedimentary rocks take millions of years to form, and metamorphic take long as well. The best answer would definitely have to be igneous.
Sedimentary rock formation can take anywhere from thousands to millions of years. It is a slow process that involves the accumulation of sediments, compaction, cementation, and solidification over time. The exact duration can vary depending on factors such as the type of sediment, environmental conditions, and geological processes.

it doesn't take long maybe 2-4 days it depends if its gonna melt then try up maybe 23 hours
Rock caverns are not built they are eroded out of solid rock by natural processes.
