History of Collect Rocks Day
The history of Collect Rocks Day can be traced back to two main subjects: 1) the history of our home — Earth and 2) the history of the science that studies the solids, liquids, and gases that constitute our planet — geology.
It’s difficult to give a brief explanation of how Earth was formed so we’re going to skip forward a few million years and learn about geology. After all, this is more in tune with the day we want to celebrate. Humanity has always been curious about how rocks are formed. Ancient civilizations would find explanations that were based more on superstition than scientific rigor.
James Hutton is considered by many to be the first geologist. He was a doctor and farmer who retired to dedicate his time to study the formation of rocks. He disputed some popular beliefs amongst the scientific community around the assertion that all rocks were formed under the sea.
By the 20th century, studies in geology helped push theories about the exact age of planet Earth and how continents were shaped. Advances in this science have been so great that humans not only study the formation of rocks on Earth but also on other celestial bodies such as the Moon. Geology has contributed a body of knowledge that helps us understand the planet we inhabit and the effects our activities have on it.
