Theory of uniformitarianism.
The idea that processes occurring now on Earth are much the same as those that occurred long ago is called uniformitarianism. This principle suggests that the same natural laws and processes that operate in the present have always operated in the past to shape the Earth's surface.
This odd-sounding dictum is a summary of Scottish geologist Charles Lyell's idea of uniformatarianism, the idea that geologic processes that are currently occurring are the same processes that occurred in the past. In short, the historical and observable geologic events that are occurring are the 'key' to unlocking the history of the geologic events that have occurred and were recorded in the rock record.
Uniformitarianism is the assumption that the same natural laws and processes that operate in the universe now have always operated in the universe in the past and apply everywhere in the universe
Uniformitarianism is the assumption that the same natural laws and processes that operate in the universe now have always done so. It is also the idea that these laws apply everywhere in the universe.
I always said "assumption to the throne" but just to confirm that, I checked with Google. There were about 46,000 pages that said "assumption to the throne" and only 3 that said "assumption on the throne".
Yes, Earth is constantly changing due to natural processes such as plate tectonics, erosion, and weathering. These processes have been occurring over billions of years and continue to shape the planet's surface and landscapes.
Always.
The false belief that all geological processes have always proceeded at the same rate is known as uniformitarianism. This idea suggests that the same geological processes occurring today have always shaped the Earth's surface in the same manner over time, but this may not always be the case due to factors like changing environmental conditions or catastrophic events.
Uniformitarianism is the assumption that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past. Thus the processes and results of a volcano erupting now are assumed to be the same as or similar to volcanoes of the past. This allows us to interpret the geological structures deposited by fossil volcanoes and infer the processes that caused them.
The only number that is always a factor is 1. This is based on my assumption that there are no decimals in your answer.

This is an assumption you have made and it isn't always true.
