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 information!

History

People in ancient times were curious. They were probably more inquisitive than us! However, geology was more geared towards understanding the Earth as a whole, including 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 concluded 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, and earthquakes – all of which 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 on the tops of mountains. Another founder of the field is Eratosthenes, who spoke amazingly accurately about the earth’s circumference. Theophrastus considered rocks to be his specialty, studied the hardness of rocks, and methods of use. Pliny continued his work.

Interesting Facts

• are most often found in the form of granite;
• determine the height of the mountain;
• can be porous, dense, and loose;
• do not exist without impurities – they almost always contain various chemical elements;
• over the years, they can transform into other types of rocks. This happens under certain conditions of temperature, pressure…
