Discontinuity in earth layers wikipedia
WebThe Conrad discontinuity corresponds to the sub-horizontal boundary in the continental crust at which the seismic wave velocity increases in a discontinuous way. This boundary is observed in various continental regions at a depth of 15 to 20 km, but it is not found in oceanic regions. The Conrad discontinuity (named after the seismologist ...

WebMar 8, 2024 · Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles). Planet Earth is older than the core.
WebAnd the boundary between what we now know to be the crust and this denser layer, which we now to be the mantle, is actually named after him. It's called the Mohorovicic discontinuity. And sometimes this is called the Moho for short. So that boundary between the crust and the mantle is now named for him.
