"Erratics" are large rocks that are not the same as the rock types found in the area and are deposited by the glaciers as they move or melt.

<h3>What are erratics?</h3>

Stones and rocks that were carried by a glacier and then abandoned after the glacier melted are known as glacial erratics.

Some characteristics of erratics are-

  • The bedrock where the glacial erratic is deposited has a distinct lithology from the sort of rock that makes up the glacier erratic.
  • A sandstone boulder moved by a glacier and placed on top of limestone bedrock would be an example of an erratic.
  • Scientists can identify and locate the source outcrop of some erratics because they are made of a particular type of distinguishable rock.
  • In order to recreate historical glacier flow directions, the timing of glacier retreat, and even the type of glacier flow, it is helpful to analyze glacial erratics.
  • Large boulders, tiny stones, and pebbles can all be erratic. Every erratic is made of a unique sort of rock.
