The theory of uniformitarianism is a theory that suggests that the changes in the crust of the Earth have been the result of geological activities that have been continuous and uniform processes. This theory doesn't really have big following in the present, though it has been much more popular in the past. The reason for that is that there have been numerous evidence that the changes in Earth's crust have not been created constantly by the same processes throughout the whole geological past. The supporters of this theory still stay strong on their beliefs though despite the evidence, and they offer other ''evidence'' that support their opinion.
