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

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 answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
