Origin and Evolution of aesthenosphere

First Known Use: 1914 year

Language of Origin: Greek

Story behind the word: The word 'aesthenosphere' was coined in the early 20th century by the geophysicist Richard Oldham.

Evolution of the word: Originally used to describe the partially molten layer of the Earth's mantle, the term 'aesthenosphere' has since become a key concept in geology and plate tectonics, referring to the region of the mantle that is ductile and flows slowly over geological time scales.
