Explain how the principle of uniformitarianism would help geologists determine the source of a layer of particular igneous rock ?

Respuesta :

Answer:

Uniformitarianism gave us a tool to interpret the geologic past. In fact, geologists sometimes summarize the concept in the phrase: The present is the key to the past. The concept is applied to all types of geologic processes. ... The other big idea inherent in uniformitarianism is that Earth is a very old place.

Explanation:

The present is the key to the past. He called this the principle of uniformitarianism. It is that if we can understand a geological process now and we find evidence of that same process in the past, then we can assume that the process operated the same way in the past.
