The term “anticlinal” is a geological term used to describe a fold in rock layers that has an upward arch. It is a term that is commonly used in the field of geology and is an important concept for understanding the structure of the earth’s crust.
Definitions
An anticlinal is defined as a fold in rock layers that has an upward arch. It is formed when two layers of rock are pushed together, causing them to bend and fold. The highest point of the fold is called the crest, while the lowest point is called the trough.
Origin
The term “anticlinal” comes from the Greek words “anti” meaning opposite and “klinein” meaning to lean. The term was first used in the 19th century by geologists to describe the structure of rock formations.
Meaning in different dictionaries
According to the Oxford English Dictionary, the term “anticlinal” refers to “a fold in rock layers that has an upward arch.” The Merriam-Webster dictionary defines it as “a fold or arch of rock layers in which the layers slope downward from the crest.”
Associations
Anticlinals are often associated with the formation of mountains and other geological features. They are also important for the extraction of oil and gas, as they can trap these resources within the folds of the rock layers.
Synonyms
Some synonyms for the term “anticlinal” include arch, fold, ridge, and crest.
Antonyms
The antonyms of “anticlinal” are “synclinal” and “downward fold.” A synclinal is a fold in rock layers that has a downward arch, while a downward fold is a fold in which the layers slope downward from the crest.
The same root words
Some words that share the same root as “anticlinal” include “incline,” “decline,” and “recline.” These words all come from the Latin word “clinare,” meaning to bend or lean.
Example Sentences
- The geologist pointed out the anticlinal formation in the rock layers.
