mantle and crust
crust and mantle, known as the MohoroviΔiΔ discontinuity or Moho. This boundary is where seismic waves change speed, indicating a transition between the Earth's outermost solid layer (crust) and the underlying denser layer (mantle).
Seismic waves
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, geologist often rely on indirect methods such as evidence from seismic waves, not fossils.
They use direct evidence from rock samples and indirect evidence from seismic waves.
By studying how seismic waves travel through the Earth's interior.
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.

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.

For a closed shape, they are point inside its boundary or perimeter.
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 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.
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.
