How did Andriza Mohorovicic discover moho?
Andrija Mohorovicic discovered the Moho boundary, or Mohorovicic discontinuity, in 1909 by observing the travel times of seismic waves. He noticed a sudden increase in seismic wave velocity at a certain depth in the Earth's interior, which indicated a change in composition and density between the Earth's crust and mantle. This boundary was later named after Mohorovicic in recognition of his discovery.
To study earth's interior geologists often rely on indirect methods such as evidence from fossils?
To study earth's interior, geologist often rely on indirect methods such as evidence from seismic waves, not fossils.
What method do they use to study the interior of Earth?
They use direct evidence from rock samples and indirect evidence from seismic waves.
Which evidence recorded at seismic stations following an earthquake supports the inference that Earth's interior changes from Solid Rock to Molten iron and nickel at the mantle core boundary?
Seismic waves generated by earthquakes provide crucial evidence for understanding Earth's internal structure. When these waves are analyzed, it is observed that P-waves (primary waves) can travel through both solid and liquid, while S-waves (secondary waves) can only travel through solids. The fact that S-waves do not reach seismic stations on the opposite side of the Earth indicates the presence of a liquid outer core, composed of molten iron and nickel, which lies beneath the solid mantle. This discontinuity in wave propagation supports the inference that there is a transition from solid rock in the mantle to molten metal at the core-mantle boundary.
Boundary between earth's crust and mantle?
It is called the Mohorovičić discontinuity or the Moho for short.It was one of the fist features of the Earth's interior that was discovered using seismic waves. In 1909, Andrija Mohorovicic discovered this boundary and it was named in his honor.
What is the synonym and antonym of plate boundary?
Synonym: Tectonic boundary Antonym: Interior boundary
What is the boundary between the interior and the exterior of the cell?
Plasma membrane
What is the boundary between the interior and exterior of the cell?
Plasma membrane
Who discovered Gutenberg Discontinuity?
The Gutenberg Discontinuity was discovered by Beno Gutenberg and Charles Francis Richter in the early 20th century. It is a boundary within the Earth's interior where seismic waves change velocity, indicating a change in composition between the outer core and the lower mantle.
Who discovered the interior of Africa?
The British
What are interior points in geometry?
For a closed shape, they are point inside its boundary or perimeter.
What is the difference between interior optimum and boundary optimum?
The interior optimum method uses an a choice that is determined by the position of an agent at a tangency that rests between the curves of two points on a graph. The boundary optimum method analyzes the position of waves.
Geologists learn about Earths interior using indirect evidence from?
Geologists learn about Earth's interior using indirect evidence from seismic waves, magnetic field data, and rock samples from volcanoes and deep drilling. These methods help provide insights into the composition, structure, and properties of Earth's interior layers.
Difference between boundary fill and flood fill?
boundaryfill fills area till the single boundary color is reached whereas floodfill fills area not defined by single boundary colourfloodfill replaces interior colour instead of searching for boundary colour
How do you obtain indirect evidence about earths interior?

How to describe one way in which geologists have gained indirect evidence about earths interior?
Studying how seismic waves refract inside the earth and if they "cast shadows" indicating that some layers inside earth are opaque to some types of seismic waves. Seismic waves "illuminate" the interior of the earth like light waves illuminate a room, permitting what is there to be seen if you have the correct tools to observe them.
