GLACIAL BOULDER Meaning and
Definition
-
Glacial boulder refers to a large, rounded or irregularly-shaped rock that has been transported by a glacier and deposited in a different location during glacial activity. These boulders are commonly formed and carried by glaciers, which are massive sheets of ice that slowly move over the land surface due to their immense weight and gravity. A glacial boulder may vary in size, ranging from several centimeters to several meters in diameter.
The formation of glacial boulders begins with the process known as glacial erosion, where glaciers scour and grind the bedrock beneath them. As the glaciers move, they pick up, pluck, and transport rock debris, which includes boulders, from their original locations. These rocks can become embedded within the ice or rest on top of the glacier, being carried along its path of movement.
When the glacier eventually reaches its melting point or encounters a barrier that impedes its movement, the boulders contained within the ice are dropped and deposited in the surrounding area. This process is known as glacial deposition. Glacial boulders can be found in various landscapes, including moraines (accumulated debris at the edge of a glacier), glacial till (the unsorted sediment left by a glacier), or on flat surfaces where the ice may have melted away.
Glacial boulders often exhibit characteristics indicating their glacial origin, such as striations (grooves and scratches) caused by the movement and grinding action of the glacier. These boulders can hold valuable information about the past glacial activities and the landforms they have shaped.

Etymology of GLACIAL BOULDER
The word "glacial" comes from the Late Latin word "glacialis", which means "icy" or "frozen". It is derived from the Latin word "glacies", meaning "ice".
The word "boulder" comes from the Middle English word "bulder", which means a large rock or stone. Its origin is uncertain, but it might be related to the Old English word "bealdan", meaning "to prepare" or "to act boldly".
When these two words are combined, "glacial boulder" refers to a large rock or stone that has been transported and deposited by a glacier. The term is often used in geology to describe a specific type of rock formation.
