Every year on January 7, Old Rock Day is commemorated to remember the Earth's incredible history and to honour the amazing geologists who help us to understand it. We've been reliant on rocks since the dawn of time, and it's no different today, with rocks being foundational of our daily lives.
What is a rock?
A rock is a solid mass that is made up of minerals or mineral-like substances. They make up the Earth's outermost layer. Rocks have been (and will continue to be) used for a variety of purposes. This encompasses a wide range of items, from weapons to musical instruments and tools, and their applications are numerous. Thus, the day- Old Rock Day is celebrated to honor these valuable structures and to learn about human development. When it comes to understanding the history of our planet and learning more about the Earth in general, old rocks are crucial. Many questions about Earth's formation can be answered by studying old rocks. They can tell scientists what happened to cause the rocks to form, as well as the effects these natural events had on other forms of life in the area. These rocks help in finding the ancestral history of flora and fauna. Plants, animals, and other organisms have their remains preserved in the rocks. These fossils can help scientists figure out what kind of fauna and flora lived in the past. They can then investigate further to determine what caused them to become extinct or evolve. This is yet another way that rocks assist us in comprehending the world we live in.
HISTORY
Theophrastus introduced the study of rocks in his work "Peri Lithon" and it became the cornerstone of geology for other scientists. Pliny the Elder researched rocks by recording numerous minerals and metals in great detail, with a particular focus on their practical applications. Pliny was able to correctly identify the origin of Amber. In 1785, James Hutton wrote and presented a paper called "Theory of the Earth" to the Royal Society of Edinburgh, outlining his belief that the world was much older than previously thought. His achievements have earned him the title of "first modern geologist." Scientists could finally provide an accurate figure for the age of the earth by tracing radioactive impurities found in rocks thanks to the invention of radiometric dating in the early twentieth century. It assisted scientists in realising that the Earth is a very old rock!
