Who discovered the discontinuities?
However, few know the name of Inge Lehmann, the Danish seismologist who discovered the discontinuity that separates the outer core from the inner core.
What is the Gutenberg discontinuity?
Gutenberg discontinuity: at a depth of 2,900 km, between the mantle and the core.
Why is it called a Gutenberg discontinuity?
The Gutenberg discontinuity (named after Beno Gutenberg (1889 – 1960), one of the most important German seismologists and geophysicists) represents the lower edge of the lithosphere and thus the solid outer area of the Earth, which has been broken into several tectonic plates.
What did Andrija Mohorovicic discover?
He was a professor at the University of Zagreb and specialized in the study of the propagation of seismic waves. His main contribution was the discovery, in 1909, of the discontinuity between the mantle and the earth’s crust (Mohorovicic discontinuity).

Who was Inge Lehmann?
A day like today, but in 1888, Inge Lehmann, a prominent Danish seismologist, was born. In her work entitled “P” (Lehmann, 1936), from the study of seismic waves, she proposes the existence of a discontinuity in the internal structure of the Earth, which divided the core into two parts: inner core and outer core. external nucleus.
What is meant by discontinuity?
Discontinuity is a term used in geology to designate the limits, especially in the interior of the Earth, between layers with rocks of different densities (the so-called density discontinuities or seismic discontinuities), but also to designate different sedimentary facies, although the latter . ..
What are the discontinuities inside the Earth called?
the Conrad discontinuity (upper crust-lower crust boundary) the Mohorovičić discontinuity or “Moho surface” (crust-mantle boundary) the Gutenberg discontinuity (lithosphere-asthenosphere boundary) the Lehmann discontinuity (also 210 km discontinuity) and .
What is the temperature of the Gutenberg discontinuity?
Its upper limit is the Gutenberg discontinuity, located at a depth of about 2,885 km, while its lower limit is the Lehmann discontinuity, located at a depth of about 5,155 km. It is about 2,270 km thick. Its temperature varies from 4,400 °C in its upper region to 6,100 °C in its lower zone.
Which of the discontinuities was discovered by a lady?
In simple terms, what Inge Lehmann discovered was that the primary waves in the seismological record, known as ‘P’ waves, are accelerated as they pass inward through the discontinuity separating the two parts of the core. Inge Lehmann was born on May 13, 1888 in Denmark.
What did Beno Gutenberg discover?
Beno Gutenberg (Darmstadt, German Empire, June 4, 1889 – January 25, 1960) was a German seismologist. Among other contributions, he defined the diameter of the Earth’s core and its boundary with the mantle, called the Gutenberg discontinuity in his honor.
What are the 5 discontinuities?
The main discontinuities that we find in the interior of the earth are the following:
- 1-Mohorovicic Discontinuity.* This discontinuity is widespread throughout the Earth. Separate crust and mantle. 2-Repetti discontinuity.3-Gutenberg discontinuity.4-Wiechert-Lehmann discontinuity.
How many types of discontinuities are there?
Types of discontinuities
- Avoidable discontinuity. Inevitable finite jump discontinuity. Inevitable infinite jump discontinuity.
What types of discontinuity exist?
Discontinuity types for a function
- Avoidable discontinuity. Inevitable discontinuity.
What is meant by seismic discontinuity?
Seismic discontinuities are the areas where abrupt changes in the speed of P and S waves occur.
What is territorial discontinuity?
The existence of discontinuities or “enclaves” in the current cartography of municipalities, that is, of land that, although within a certain municipal perimeter, belongs to a neighboring or nearby municipality, in many cases has a historical origin, dating back to even to medieval times.
What is a discontinuous territory?
In morphological and functional terms, this word is used to indicate the population that occupies territories that extend beyond the traditional city with low densities (Monclús, 1998) and is associated with a disruption between the old urban fabrics and their extensions (Panerai , 1983).
What was Inge Lehmann’s great discovery?
It was the Danish seismologist Inge Lehmann who discovered that the center of the Earth is actually a hard core, surrounded by a liquid outer layer. Ella inge was born in Copenhagen and educated in a very progressive school for the time that treated men and women equally, an anomaly at the time.
How was the mantle mold discovered?
1. S. [Geología]
This boundary, commonly referred to as “the Moho,” was recognized in 1909 by Croatian seismologist Andrija Mohorovicic based on the abruptly higher compressional wave (P-wave) velocity that characterized it.
How was the mantle discovered?
The knowledge we have of the mantle is essentially based on indirect geophysical studies, especially on the study of the propagation of seismic waves, and on the study of rock samples from great depths that are brought to the surface by the orogeny or by volcanism (ophiolites, kimberlites and …
Where is the Mohorovicic located?
The Mohorovicic Discontinuity, better known simply as “Moho”, is the transition zone between the crust and the upper mantle, and a basic surface for any geophysical study of the Earth’s crust.
What are static model discontinuities?
COMPOSITIONAL OR STATIC MODEL. It divides the Earth into three layers: crust, mantle, and core. Separated by boundaries where the composition changes, called discontinuities.
