Question

In the earth's structure, what is the name for the sharp boundary between the crust and the mantle?

Answer 1

The sharp boundary between the crust and the mantle is known as the Mohorovičić discontinuity or Moho. It was named after Croatian seismologist Andrija Mohorovičić who discovered it in 1909. It separates the Earth's thin, brittle outer layer from the plastic, flowing mantle below.

Answer 2

The sharp boundary between the crust and the mantle is known as the Mohorovičić discontinuity, or the Moho. This boundary marks the transition from the Earth's brittle outer crust to the more plastic mantle below.

Answer 3

The sharp boundary between the Earth's crust and the underlying mantle is called the "Mohorovičić discontinuity," often referred to as the "Moho" for short. This boundary represents a significant change in seismic wave velocities, indicating the transition from the relatively brittle and solid crust to the hotter and more ductile mantle beneath. The Moho is an important feature in understanding the Earth's internal structure and the division between its outermost layer and the layer below.
