Detailed explanation-1: -This theory states that the forces and processes observable at earth’s surface are the same that have shaped earth’s landscape throughout natural history. The earth sculpting processes alluded to above are the processes of erosion, deposition, compaction and uplift.
Detailed explanation-2: -uniformitarianism, in geology, the doctrine suggesting that Earth’s geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity is sufficient to account for all geologic change.
Detailed explanation-3: -What does uniformitarianism tell us about processes at work on Earth’s surface today? Physical, chemical and biological laws today operated in the geological past. What does relative dating tell us? Sequence in which events occurred.
Detailed explanation-4: -In the first of three volumes, Charles Lyell sets forth the uniformitarian argument: processes now visibly acting in the natural world are essentially the same as those that have acted throughout the history of the Earth, and are sufficient to account for all geologic phenomena.
