How was Moho discovered?
The Moho is widely believed to be the boundary between Earth’s crust and an underlying layer of denser rocks in Earth’s interior called the mantle. It is named after Croatian seismologist Andrija Mohorovicic, who first detected it in 1909 by examining seismic waves moving through the Earth.
When was the Moho discontinuity discovered?
8, 1909
Earth sciences: Seismology and the structure of Earth 8, 1909, the geophysicist Andrija Mohorovičić discovered the discontinuity (often called the Moho) that……
Which is the thickest layer of the earth?
core
The core is the thickest layer of the Earth, and the crust is relatively thin, compared to the other layers.
What is the Moho level?
The Moho is the boundary between the crust and the mantle in the earth. This is a depth where seismic waves change velocity and there is also a change in chemical composition. Also termed the Mohorovicic’ discontinuity after the Croatian seismologist Andrija Mohorovicic’ (1857-1936) who discovered it.
Where is the Moho barrier?
The Mohorovicic discontinuity (the Moho) is the boundary lying between the crust and the mantle of the earth across which seismic waves change velocities. This boundary is located approximately 24 miles below the earth’s surface and 6 miles below the oceanic floor, a distance which varies from place to place.
Where does the Moho lie in the Earth’s crust?
See Article History. Alternative Title: Mohorovičić discontinuity. Moho, or Mohorovičić discontinuity, boundary between the Earth’s crust and its mantle. The Moho lies at a depth of about 22 mi (35 km) below continents and about 4.5 mi (7 km) beneath the oceanic crust.
How is the Moho related to the mantle?
The Moho is clearly defined by seismic studies, which detect an acceleration in seismic waves as they pass from the crust into the denser mantle. …crust may accumulate near the Moho, which is a discontinuity that separates Earth’s crust from its mantle.
Who is the Moho and why is it called that?
Named after the pioneering Croatian seismologist Andrija Mohorovičić, the Moho separates both the oceanic crust and continental crust from underlying mantle.
