what was andrija mohorovicic major contribution to geology?

His most significant contribution to science is the discovery that crust and mantle are separated by a discontinuity. A major earthquake in Croatia provided Mohorovicic with empirical evidence that helped him find the crust-mantle boundary and the boundary between the core and the mantle.

What was Andrija Mohoroviii major contribution to Earth science?

Jan. 29, 1980), (born Andrija Mohorovi*i*), has a married name of Mohorovi. He died on December 23, 1857, in Volosko, Croatia, now part of Croatia. The date is August 18, 1936, in Zagreb, Yugoslavia. Croatian meteorologist and geophysicist. Discovered the boundary between Earth's crust and mantle, which was subsequently named the Mohorovi*i* discontinuity for his discovery.

What was the major contribution of Andrija Mohorovicic to earth science quizlet?

is the greatest c to Earth science? Several hypotheses have been proposed regarding why seismic waves at certain depths blow the surface of the earth faster than they once would have. Dense rock causes the waves to travel faster.

How did Andrija Mohorovicic discover the compositional differences between the mantle and crust?

Based on his studies on the earthquake after it occurred, he concluded there were two types of waves generated by an earthquake. As waves bounce off and refract when they reach a boundary between two different types of materials, the boundary between the crust and the mantle, for example.

How did Andrija Mohorovicic discovered the mantle?

Despite having thought that readings would reach his instruments slowly, Mohorovicic was surprised when some did. The slow waves traveled in the crust while the faster ones traversed a deeper, denser layer of Earth, called the mantle.

What did Croatian scientist Andrija Mohorovicic discover in 1909?

In 1909, a Croatian seismologist named Andrija Mohorovicic discovered the Mohorovicic Discontinuity, which explains that seismic waves' velocity is affected by the density of the medium through which they are moving. Obviously, this acceleration is due to deeper layers of density-higher material.

What was Mohorovicic observation quizlet?

A prism bends light as it passes through it, which is how the waves reflect and refracted. By observing the speed of the seismic waves, we were able to identify the difference between the mantle and the crust, now called the Mohorovi*i* discontinuity, which progressively improved our understanding of Earth's structure.

Which region in the earth is molten quizlet?

You must know every layer of the Earth and its currents of convection. As a result of the intense heat, some rocks found in the lithosphere have melted and are flowing. Science has determined that the Earth's outer core consists of liquid due to deep wells. It is made up mostly of iron and is liquid in the center of the Earth.

What is liquefaction geology quizlet?

Liquidification. It occurs when water is saturating unconsolidated materials (loosely arranged materials). Stable soil can become a fluid when it is shaken by earthquake vibrations. Water gets squeezed out as grains are rearranged and water pressure increases.

How did Andrija Mohorovicic discovered the Moho?

Known as informally Lagrangian, the Moho was first defined and discovered by Croatian seismologist Andrija Mohorovi*i*. His findings were made while he was examining quake data from Zagreb when he observed that two distinct sets of P-waves and S-waves occurred from the core of the quake.

How the boundary between crust and mantle was first discovered?

Located in the earth, the Moho divides the crust from the mantle. It is a depth at which the velocity of seismic waves changes and where chemical composition also changes. As a result of Croatian seismologist Andrija Mohorovicic' (1857-1936) who discovered it, called the Mohorovicic discontinuity.

Who discovered the mantle?

The Croatian seismologist Andrija Mohorovicic (1857-1936), who discovered the crust and Earth's mantle in 1909, helped reveal what he believed to be the existence of these layers.
