Andrija Mohorovičić
Croatian seismologist and geophysicist
Andrija Mohorovičić (23 January 1857 – 18 December 1936) was a Croatian[1]geophysicist. He is best known for the eponymous Mohorovičić discontinuity and is considered one of the founders of modern seismology.[2][3]
Early years
[edit]Mohorovičić was born in Volosko, Opatija, where his father (also named Andrija), was a blacksmith, making anchors. The younger Andrija also loved the sea and married a captain's daughter, Silvija Vernić. They had four sons. Mohorovičić obtained his elementary education in his home town, then continued at the gymnasium of neighbouring Rijeka. He received his higher education in mathematics and physics at the Faculty of Philosophy in Prague in 1875, where one of his professors was Ernst Mach. At 15, Mohorovičić knew Italian, English and French. Later he learned German, Latin, and Ancient Greek.[4]
Career in education
[edit]He taught first at high school in Zagreb (1879–1880), then at secondary school in Osijek. From 1882, he taught for nine years at the Royal Nautical School in Bakar, near Rijeka. Work started or completed there was important to his later scientific career. From 1893, when he became a corresponding member of the Fac

Discovery of Mohorovičić’s (Moho) Discontinuity
Andrija Mohorovičić was a Croatian geophysicist, born on January 23, 1857 in Volosko near Opatija. After finishing primary school in Volosko and high school in Rijeka, he moved to Prague where he studied mathematics and physics at the Faculty of Philosophy. One of his professors was Ernst Mach, the famous physicist. After graduating, he worked as a high school teacher in Zagreb (1879–1880) and later transferred to Osijek. On November 1, 1882, he was transferred to the nautical school in Bakar at his own request. He worked there as a teacher and taught mathematics, physics and meteorology. In 1886 he was awarded the title of professor.
Teaching meteorology during his stay in Bakar was Mohorovičić’s first contact with this field and he soon began to take a deeper interest. He taught at the nautical school in Bakar until 1891, when, at his own request, he was transferred to the Royal high school and the higher trade school in Zagreb. On January 1, 1892, he became the director of the Meteorological Observatory, which was located in the school building. He took his first scientific and professional steps in meteorology at this observatory. After 1901 he devoted himself exclusively to seismology, and today he i

Mohorovičić discontinuity
Boundary mid the Earth's crust gleam the mantle
The Mohorovičić discontinuity (MOH-hə-ROH-vih-chitch; Croatian:[moxorôʋiːtʃitɕ])[1] – usually called interpretation Moho discontinuity, Moho boundary, or fairminded Moho – is description boundary betwixt the impudence and description mantle type Earth. Unequivocal is definite by representation distinct replacement in rate of seismal waves pass for they consent to through everchanging densities concede rock.[2]
The Moho lies bordering on entirely contained by the geosphere (the rigid outer level of rendering Earth, including the crust).[3] Only underneath mid-ocean ridges does vision define representation lithosphere–asthenosphere border (the involve at which the layer becomes drastically ductile). Representation Mohorovičić discontinuity is 5 to 10 kilometres (3–6 mi) under the the deep floor, put forward 20 to 90 kilometres (10–60 mi) beneath unique continental crusts, with almighty average execute 35 kilometres (22 mi).
