How do you know all that is true?
In short, it works. Mineral and oil exploration depends on geology and, in particular, structural geology. In order to define an ore body, you have to understand the natural processes which lead to its formation. Plate tectonics provides a starting point for these definitions today but long before the general acceptance of continental drift, the idea that long periods of time were essential in the formation of geological structures. You can go back to geologic descriptions that were written 100 + years ago of ore bodies and you will see descriptions of processes that took millions of years. Porphyry ore zones were recognized very early and their localized formation and ages understood.
In all this, flood geology has no explanatory value. Certainly there have been many localized floods that have altered the surface of the land in dramatic ways. The Scablands of Eastern Washington state are one example. However these features are related to local occurrences. In Washington, melting ice caps formed massive lakes whose containment failed periodically. This produced massive floods. However, someone living in the Southwest would never have noticed them. They would be subjected to the melting of glaciers and ice caps in the Rocky Mountains which rushed down the Colorado River.
Plate tectonics and structural geology work, they answer questions, are confirmed by the existence of mountain ranges, volcanos, great rift areas and subduction zones. Satellite photos show clearly the boundaries of the ring of fire, for example. Great undersea troughs exist at the edges of tectonic plates as do volcanically active margins lining them. Mid-ocean ridges can be shown to be allowing the spread of the ocean floor.
It all works and is explanatory of what we see. Certainly, there are yet questions but that’s how real science works.
JimSEA and evolution have no explanation for polystrate fossils either.
