Beno Gutenberg, a prominent seismologist, contributed to the understanding of the Earth's outer core through his analysis of seismic wave behavior. In the early 20th century, he studied how seismic waves generated by earthquakes traveled through the Earth. He observed that certain seismic waves, specifically S-waves (shear waves), could not pass through the outer core, indicating that it was liquid. This observation, combined with the differing behavior of P-waves (compressional waves), led to the conclusion that the outer core is composed of molten material.

Who formulated the Gutenberg discontinuity?
The Gutenberg discontinuity was formulated by Beno Gutenberg, a German seismologist, and Charles Francis Richter, an American seismologist, in the early 20th century. It is a boundary within the Earth's mantle that separates the lower mantle from the outer core based on differences in seismic wave velocities.
How did Beno Gutenberg discover the boundary between mantle and outer core?
He didnt just discover 'a boundary' between mantle and outer core. He provided the first reasonable accounting of Earths interior (proved the thought that the earth was in layers and not just a homogenous planet). He was also the first to estimate the temperature and physical properties of the earths core, which is why the boundary is called after him. He first discovered the layers through seismic waves from earthquakes, realising they had different magnitudes and intensity because they must have had to go through layers before reaching the surface as well as depending where the epicentre is.
What is a fact about the earths outer core?
The Earth's outer core is composed mainly of liquid iron (85 %) and nickel (5 %) with the rest made up of a number of other elementsThe outer core is 2,260 km thickThe outer core's upper boundary is 2,890 km (1,806 miles) below the surfaceThe outer core's lower boundary is 5,150 km (3,219 miles) below the surfaceThe temperature of the outer core varies from 4400 degrees C at it's upper boundary and 6100 degrees C at it's lower boundaryThe outer core accounts for approximately 31 % of Earth's mass The layer above the outer core is known as the mantle and the boundary itself is known as the Gutenberg discontinuity, named after the the German geophysicist Beno Gutenberg who discovered it. Gutenberg is also famous for his work with Charles Richter in the development of the Richter magnitude scale.The layer below the outer core is the inner core and this boundary was discovered by the Danish geophysicist Inge LehmannGeophysicists currently believe that the convection of the molten iron in Earth's outer core produces Earth's magnetic field which protects us from solar radiation and without which life on Earth as we know it would have been impossibleSome geophysicists also believe that certain mantle plumes form at the boundary between the outer core and the mantle due to the very high differences in temperature (the outer core is much hotter than the base of the mantle above it). It is these hot plumes that are thought to be responsible for volcanism at hot spots in the middle of tectonic plates such as the one that created the Hawaiian island chain.
What is thickness of the Gutenberg Discontinuity?
The Gutenberg Discontinuity, located between the mantle and outer core of the Earth, is estimated to be around 250 kilometers thick. It marks the transition from the solid mantle to the liquid outer core, where seismic waves experience a sudden increase in velocity.
The liquid layer of earths core between mantle and inner core?
Gutenburg Discontinuity
Who discovered Gutenberg Discontinuity?
The Gutenberg Discontinuity was discovered by Beno Gutenberg and Charles Francis Richter in the early 20th century. It is a boundary within the Earth's interior where seismic waves change velocity, indicating a change in composition between the outer core and the lower mantle.
What is Internal layer between earths mantle and inner core?
I think there is a layer called the Gutenberg Discontinuity named after a german seismologist named Beno Gutenberg between lower mantle and outer core.
Who formulated the Gutenberg discontinuity?

The Gutenberg Discontinuity is found directly above this layer of the earth.?
The Gutenberg discontinuity is found directly above the outer core.
The Gutenberg Discontinuity is found beneath this layer?
The Gutenberg Discontinuity is found above the earth layer called the outer core. This boundary line, which separates the outer core from the lower mantle, is approximately 1798 miles below the Earth's surface.
What is the meaning of Gutenberg Discontinuity?
The Gutenberg Discontinuity is a boundary within the Earth between the outer core and the inner core. It is characterized by a rapid increase in seismic wave velocities, indicating a change in composition and material properties between the liquid outer core and the solid inner core.
What is named after the German geologist that discovered the thing that separates the earth's mantle from the outer core?
the Gutenberg discontinuity

What is the difference between Mohorovicic discontinuity and Gutenberg discontinuity?
Mohorovicic discontinuity is located between the upper mantle and the crust, while the Gutenberg discontinuityis located between the lower mantle and the outer core.
What is thickness of the Gutenberg Discontinuity?
The Gutenberg Discontinuity, located between the mantle and outer core of the Earth, is estimated to be around 250 kilometers thick. It marks the transition from the solid mantle to the liquid outer core, where seismic waves experience a sudden increase in velocity.
How did geologists locate the Gutenberg discontinuity?
We know the discontinuity exists because of different types of seismic waves; certain waves can penertrate to different depths. Seismic waves are refracted at the Gutenburg discontinuity, which marks the upper boundary of the earth's core
