What layer did Gutenberg discontinuity separate?
The Gutenberg Discontinuity is situated inside the earth at a depth of about 2900 kilometres below the surface. The Gutenberg discontinuity separates the core and the mantle of the earth.
How did Beno Gutenberg help in studying the interior of the earth?
In 1941, Gutenberg published Seismicity of the Earth, which became a major influence in later scientists’ efforts to describe the theory of plate tectonics. His 1959 publication Physics of the Earth’s Interior summarized more of his views on earthquakes and the Earth’s interior.
Why is the Gutenberg discontinuity important?
Among his important scientific contributions, Gutenberg identified the depth of Earth’s core–mantle boundary (see figure 1), a discontinuity where seismic secondary waves are absorbed by the liquid core.
What did Inge Lehmann study?
Inge Lehmann, (born May 13, 1888, Copenhagen, Denmark—died February 21, 1993, Copenhagen), Danish seismologist best known for her discovery of the inner core of Earth in 1936 by using seismic wave data.
What is the Gutenberg discontinuity?
Unsourced material may be challenged and removed. The Gutenberg discontinuity occurs within Earth’s interior at a depth of about 2,900 km (1,800 mi) below the surface, where there is an abrupt change in the seismic waves (generated by earthquakes or explosions) that travel through Earth.
What is the Wiechert-Gutenberg discontinuity?
The mantle–core boundary is the Gutenberg discontinuity at a depth of about 2,800 kilometres. The outer core is thought to be liquid because shear waves do not pass through it. …its underlying mantle, and the Wiechert–Gutenberg Discontinuity, which separates the mantle from the core.
How deep is the Wiechert Gutenberg discontinuity?
…its underlying mantle, and the Wiechert–Gutenberg Discontinuity, which separates the mantle from the core. The latter discontinuity exists at a depth of 2,900 kilometres (1,800 miles); it is marked by a sudden increase in density, from about 5.7 at the base of the mantle to 9.7 at the top of…
What is another name for the Oldham-Gutenberg discontinuity?
It has also been referred to as the Oldham-Gutenberg discontinuity, or the Weichhert-Gutenberg discontinuity. See also Earthquake; Tectonics.
