Question

What do you understand by gutenberg discontinuity?

Answer 1

The gutenberg discontinuity is the boundary between the earth’s mantle and core, located at a depth of about 2900 km. It marks a significant change in material composition and properties, separating the solid mantle from the liquid outer core. This discontinuity indicates a change from silicate rocks in the mantle to metallic iron and nickel in the core, and it affects seismic wave behavior due to different densities and states of matter.
