Answer:
The principle of uniformitarianism helps answer questions about environmental changes because it gives scientists the idea that the scientific conditions that exist today have always been in existence. This makes it easier to draw correlations.
Step-by-step explanation:
The principle of uniformitarianism states that the natural conditions that exist today have remained unchanged through the span of human life. This helps scientists in their understanding of nature. For example, they are better able to understand the formation of the earth as well as the uniformity of law across space and time.
Uniformity of law is an aspect of the principle of uniformitarianism which states that the laws of nature are constant across time and space. Uniformity of degree states that geological conditions have remained constant over time. These principles help scientists to better understand environmental changes.
