National Old Rock Day

Old Rock Day is perceived by some as a musical holiday, but it is not. It is dedicated to geologists who study the environment, namely fossilized rocks. They carry a lot of interesting things!

History

People in ancient times were curious. They were probably more inquisitive even than us! However, the geology was more geared towards the Earth as a whole, about its age… Of course, there was mining, but it didn’t grow to a massive level.

In terms of reflections on geology, Ancient Greece can be noted. Even the great Aristotle carefully observed the landscapes and came to the conclusion that they are undergoing changes. He formed the idea that this is happening so slowly that you can’t see it in one lifetime. He was only half right, because there are landslides, avalanches, earthquakes – all this can change the landscape in a matter of hours.

The philosopher Xenophanes, who lived 100 years before Aristotle, was fond of paleontology. He discovered the fossils of fish falling on the tops of mountains. Another of the founders of the sphere is Eratosthenes, he spoke amazingly accurately about the earth’s circumference. Theophrastus considered rocks to be his profile, studied the hardness of rocks and methods of use. Pliny continued his work.
