What is uniformanitism?

Answer 1

I think you mean 'uniformitarianism'. According to the principle of uniformitarianism, the observable features of the world were produced by processes that are still observable today.

For example, mountains were formed, not by a miracle or a catastrophe, but by the ordinary (very slow) geological processes of plate tectonics, which we can observe in the present.

Answer 2

Uniformitarianism is the principle in geology that states the same natural laws and processes that operate in the present have always operated in the past. This principle is used to interpret past geological events and processes based on observations of present-day phenomena. It forms the foundation of modern geology and helps scientists understand the Earth's history.
