GLACIAL TABLE Meaning and
Definition
-
A glacial table is a distinctive geological feature formed by glacial erosion in mountainous or polar regions. It refers to a flat or level surface of bedrock that is typically exposed above the surrounding landscape due to the slow retreat of a glacier. The term "table" denotes its flat, tabletop-like appearance.
Glacial tables are typically found in areas where glaciers have receded, leaving behind smoothed and polished bedrock surfaces. The process of their formation begins with a glacier overriding and eroding the landscape, scraping away loose sediment and weathered material. Over time, the immense pressure and movement of the glacier cause abrasion and plucking of the underlying bedrock.
As the glacier gradually retreats, the exposed bedrock undergoes selective erosion. Glacial meltwater that accumulates on the higher parts of the table acts like a natural abrasive, wearing away the surface and forming distinct patterns, such as striations and grooves. These features provide evidence of the glacier's movement and direction.
Glacial tables can vary in size, ranging from a few meters to several kilometers in diameter, and their flat, exposed surfaces often demonstrate the characteristics of the underlying bedrock, such as layers, fractures, or other geological formations. They are significant landmarks that give insights into past glacial activity and are of interest to geologists and researchers studying the Earth's glacial history.
