Scientific Process

A systematic method used by geoscientists to make observations, and formulate and test hypotheses.

Geoscientist's Observations

Repeatable observations that inform critical decisions in geology.

Data vs Interpretations

Data is raw information; interpretations are the conclusions drawn from data analysis.

Observations vs Hypotheses

Observations are what you notice; hypotheses are testable predictions based on those observations.
