ERRATIC BLOCKS Meaning and
Definition
-
Erratic blocks are large, distinctive rock formations that exhibit irregular shapes and sizes. These blocks are typically found scattered across the surface of the Earth, resulting from glacial activity or other geological processes. They are often composed of different types of rocks, including granite, basalt, or sandstone, and can vary in weight from a few kilograms to several hundred tons.
The term "erratic" refers to the unusual and unpredictable nature of these blocks' distribution. Instead of being found in their original location, erratic blocks are transported over long distances by glaciers or other forces. This movement occurs as glaciers advance and retreat, carrying rocks embedded within the ice and depositing them when the ice melts. As a result, erratic blocks can be found in places far removed from their source rock formations.
Erratic blocks have significant scientific importance as they provide valuable insights into past glacial movements and Earth's geological history. By studying the characteristics of these rocks, geologists can determine the direction and extent of ancient ice flows, aiding in the reconstruction of past climate conditions.
In addition to their scientific value, erratic blocks also have cultural and aesthetic significance. They are often regarded as notable landmarks or tourist attractions in areas where they are abundant. These unique rock formations serve as reminders of the dynamic geological processes that have shaped the Earth over millions of years.

Etymology of ERRATIC BLOCKS
The word "erratic" originated from the Latin word "erraticus", which means "wandering" or "errant". It entered the English language around the 17th century, initially used to describe people or animals that wandered or roamed aimlessly.
The term "erratic blocks" specifically refers to large boulders or stones that have been transported over long distances by glaciers or ice sheets during the Ice Age. These blocks were left behind when the ice melted, often far away from their original source. The use of the word "erratic" in this context reflects the irregular and unpredictable nature of their distribution, as they seem to have wandered or moved in an erratic manner from their point of origin.
