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: -This is known as uniformitarianism: the idea that Earth has always changed in uniform ways and that the present is the key to the past. The principle of uniformitarianism is essential to understanding Earth’s history.
Detailed explanation-4: -Why does the principle of uniformitarianism lead to the conclusion that the age of Earth is great? The major folds and unconformities seen in rocks could not have been produced in such a short time if the principle of uniformitarianism is applied.
