An esker is a long, narrow ridge of gravel and sand that was formed by glaciers. A beaded esker is a type of esker that has a series of small, circular depressions or “beads” along its length. In this article, we will explore the definition and meaning of beaded esker.
Definitions
A beaded esker is a type of esker that is characterized by a series of small, circular depressions or “beads” along its length. These beads are typically between 1 and 10 meters in diameter and are spaced at regular intervals along the esker.
Origin
The origin of beaded eskers is not fully understood, but they are thought to have formed during the retreat of glaciers. As the glaciers melted, they deposited large amounts of sediment in the form of gravel and sand. This sediment was then shaped by the movement of water and ice, creating the distinctive ridges and depressions of beaded eskers.
Meaning in different dictionaries
The term “beaded esker” is not widely used in dictionaries, but it can be found in some geological and scientific texts. The meaning of the term is generally consistent across these sources, referring to a type of esker with small, circular depressions or “beads” along its length.
Associations
Beaded eskers are typically associated with glacial landscapes and are found in areas that were once covered by ice sheets. They are often used by geologists and other scientists to study the history of glacial retreat and the movement of sediment during this process.
Synonyms
There are no widely recognized synonyms for beaded esker, but it may be referred to as a “beaded ridge” or “beaded moraine” in some contexts.
Antonyms
There are no widely recognized antonyms for beaded esker.
The same root words
