Typically quoted along with "the past is the key to the present" (or visa versa), this concept is the idea that geologic processes occuring now have always occurred throughout earths history (although NOT always at the same rate or intensity).
Some examples: we see volcanoes erupting now, so there must have been volcanoes erupting in the past. We see animals go extinct now, so therefore animals must have gone extinct in the past. We see erosion causing sand along a beach now, so therefore sand in the geologic record must have formed at beaches. We see climate change now, so climate must have changed in the past. And so on.
Uniformitarianism is a principle in geology that states that the same natural processes that operate in the present have always operated in the past at a relatively constant rate. This principle helps geologists interpret ancient Earth processes by studying modern-day processes. It is a fundamental concept in the field of historical geology.

What is the law of uniformtarianism?
the formation of something
What is the idea developed by Charles Lyell which states that the geologic processes that shaped Earth in the past continue to operate in the same way today?
The concept of gradualism. Also called uniformtarianism.
What is the principle of uniformtarianism?
Uniformitarianism is the principle in geology that states that the same natural processes that we observe today have occurred throughout Earth's history to shape its surface. This principle helps scientists interpret past geological events by assuming that the same processes acting in the present have been acting in a similar manner in the past.
Lyell's principles of geology stated that geological features could be changed over long period of times how did this statement influence Darwin's own concept of evolution?
organisms change over time
