Who did not believe in the line of compensation but a zone of compensation?

Who proposed the theory of isostasy?

The term isostasy was proposed in 1889 by the American geologist C. Dutton, but the first idea of mass balancing of the Earth’s upper layer goes back to Leonardo da Vinci (1452–1519).

Who is the scientist who proposed the isostasy and explain the concept?

The general term ‘isostasy’ was coined in 1882 by the American geologist Clarence Dutton.

What is level of compensation in geography?

compensation level The depth at which light penetration in aquatic ecosystems is so reduced that oxygen production by photosynthesis just balances oxygen consumption by respiration. Generally this implies a light intensity of about 1 per cent of full daylight. A Dictionary of Ecology.

Who gave the idea of level of compensation with reference to the concept of isostasy?

1. Theory of Sir George Airy: According to Airy the inner part of the mountains cannot be hollow; rather the excess weight of the mountains is compensated (balanced) by lighter materials below.

What is Pratt’s concept of isostasy?

In isostasy. The Pratt hypothesis, developed by John Henry Pratt, English mathematician and Anglican missionary, supposes that Earth’s crust has a uniform thickness below sea level with its base everywhere supporting an equal weight per unit area at a depth of compensation.

What is Airy’s theory?

The Airy hypothesis says that Earth’s crust is a more rigid shell floating on a more liquid substratum of greater density. Sir George Biddell Airy, an English mathematician and astronomer, assumed that the crust has a uniform density throughout.

What is the meaning lithosphere?

The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.

What is the difference between Terrane and terrain?

What is the difference between terrane and terrain? “Terrane” describes a crustal fragment consisting of a distinct and recognizable series of rock formations that has been transported by plate tectonic processes, whereas “terrain” describes the shape of the surface topography.
