What did Croatian scientist Andrija Mohorovicic discover in 1909?

The Mohorovicic Discontinuity was discovered in 1909 by Andrija Mohorovicic, a Croatian seismologist. Mohorovicic realized that the velocity of a seismic wave is related to the density of the material that it is moving through.

Who is Andrija Mohorovicic why is he important?

Mohorovicic’s major contribution for which he is famous is the discovery of the discontinuity between the mantle and the crust. In 1909 a major earthquake in Croatia provided Mohorovicic with empirical evidence that he used to discover the division between the crust and the mantle, as well as the mantel and the core.

Who discovered the mantle?

In 1909 Andrija Mohorovicic (1857-1936), a Croatian seismologist, helped reveal the existence of the shallowest of these layers, the crust, and the underlying layer, the Earth’s mantle.

Who discovered discontinuity?

Mohorovičić
The Mohorovičić discontinuity was first identified in 1909 by Mohorovičić, when he observed that seismograms from shallow-focus earthquakes had two sets of P-waves and S-waves, one set that followed a direct path near the Earth’s surface and the other refracted by a high-velocity medium.

How was Moho discovered?

Croatian seismologist Andrija Mohorovičić is credited with first discovering and defining the Moho. In 1909, he was examining data from a local earthquake in Zagreb when he observed two distinct sets of P-waves and S-waves propagating out from the focus of the earthquake.

What are 3 amazing facts about the mantle?

Five facts about the mantle include:

• The mantle makes up 84% of Earth’s volume.
• The mantle extends from 35-2980 kilometers below Earth’s surface.
• The mantle is mostly solid rock.
• The mantle ranges in temperatures from 200 to 4000 degrees Celsius.
• Convection currents in the mantle drive plate tectonics.

When was Gutenberg discontinuity discovered?

The structure of the earth has been a subject of study since ancient times. The Gutenberg discontinuity was named after Beno Guttenberg, who contributed several important facts and understanding of the earth’s interior in 1913, which led to groundbreaking discoveries related to the inner layers of the earth.

Where is the Moho deepest?

central Hokkaido
The deepest point of the Moho is about 40 km. The Moho is deep in central Hokkaido, the northern Tohoku district, the southeastern Tohoku district, the Kinki district, Shikoku, and central Kyushu. It is relatively shallow in the Kanto district, the southwestern Chubu district, and the Chugoku district.

Who was Andrija Mohorovičić?

Andrija Mohorovičić was born in Volosko near Opatija in Croatia, on January 23, 1857. His father, Andrija came from Rukavac in Istria. He was a blacksmith who made anchors. His mother, Marija nee Poščić was born in Opatija. She died soon after Andrija’s birth.

Who was Mišo Mohorovičić?

As a meteorologist Mohorovičić was noted for his great organizational ability, his insistence on high standards of precision wherever he had responsibilities, and his success in circumventing bureaucracy.

What did Moed Mohorovičić do?

Mohorovičić contributed research papers on a variety of other topics in seismology. He evolved a method of determining earthquake epicenters and constructed curves giving the travel times of seismic waves over distances of up to 10,000 miles from the source.

How did Andrya Mohorovicic determine the discontinuity?

Andrya Mohorovicic determined the boundary between the crust and the mantle, which is now named the Mohorovicic discontinuity. Velocities of seismic waves were used to identify this boundary. He had seismographs installed before the 1909 earthquake had occurred.
