What is Mohorovicic Discontinuity explain?

What is Mohorovicic Discontinuity explain?

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.

What is the Mohorovicic Discontinuity and how was it discovered?

The Mohorovicic Discontinuity is the boundary between the earth’s crust and mantle. It was discovered by the refraction of seismic waves passing from one layer to the other.

What is the importance of Mohorovicic Discontinuity?

The Mohorovicic discontinuity is important because it marks the boundary between the mantle of liquid magma and the hardened magma that forms the curst.

What is Mohorovičić discontinuity mention its density?

Mohorovicic discontinuity is the layer which is between the earth’s crust and mantle. It’s density ranges from 3.3 to 3.7.

What is the meaning of Mohorovicic?

Mohorovičić discontinuity. / (ˌməʊhəˈrəʊvɪtʃɪtʃ) / noun. the boundary between the earth’s crust and mantle, across which there is a sudden change in the velocity of seismic wavesOften shortened to: Moho.

Where is the Mohorovicic 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.

What do you mean by Gutenberg discontinuity Class 7?

The Gutenberg Discontinuity is situated inside the earth at a depth of about 2900 kilometres below the surface. The Gutenberg discontinuity separates the core and the mantle of the earth. These layers are further divided into the upper and lower crust, upper and lower mantle, and the outer and inner core.

What is lemon discontinuity?

The Lehmann discontinuity is an abrupt increase of P-wave and S-wave velocities at the depth of 220 km (140 mi), discovered by seismologist Inge Lehmann. The thickness is 220 km. Further discussion of the Lehmann discontinuity can be found in the book Deformation of Earth Materials by Shun-ichirō Karato.

What is the meaning of the term Mohorovicic discontinuity?

Definitions for Mohorovicic discontinuity Mo·horovi·cic dis·con·ti·nu·ity. Here are all the possible meanings and translations of the word Mohorovicic discontinuity. Mohorovicic discontinuity (n.) The Mohorovičić discontinuity, usually referred to as the Moho, is the boundary between the Earth’s crust and the mantle.

Where is the Mohorovicic discontinuity in the earths crust?

A similar project is underway in Sri Lanka. The Mohorovicic discontinuity layer marks the end of the earth’s crust and is estimated to be between 1 to 4 miles thick depending on the oceanic or continental crusts. It lies below the basalt rock system and above the dunites rock systems.

Is the idea of continuous evolution a discontinuity?

Species are definitely discontinuous, and this is the only discontinuity which Nature shows us. The idea of continuous evolution is here maintained in opposition to Comte’s and Mill’s philosophy of discontinuity. In any other way, as far as I can see, there will be a discontinuity at some point on the inhabited part of the earth.

What is the cause of the Moho discontinuity?

The Moho discontinuity occurs at an average of about 8 km below the ocean basins and 30 kilometres below the Earth surface. The cause of moho is considered to be the change in rock composition from the rock containing feldspar (above) to the rock that contains no feldspar ( below).
