There is no set time for rock formation. The time necessary for rock formation lie somewhere on a scale from hours to millions of years.
10,000,000+ years
Typically thousands to hundreds of thousands 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.

Magnetite is an extremely rare metal (rock) and can take 459,000 to 23,000,000 years to form.
10,000,000+ years
millions of years
From bare rock... I think 80yrs.
Typically thousands to hundreds of thousands of years.
17 hours
Generally speaking, the creation of clastic sedimentary rock is part of a long process of weathering, erosion, deposition, compaction, and cementation that can take millions of years.
a long time. Acid rain and other erosion methods erode the rock to form a cave then an arch then a stack
around 5 hours
Most metamorphic rock processes involve very long periods of time. The exception would be metamorphic rocks formed by meteorite impacts.
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.
