Answer:
Explanation:
Discontinuities are changes that seismic waves present in their trajectory and speed because the properties of the medium they pass through become different. That is what has allowed geologists and geophysicists to know the internal structure of the planet and deduce its composition.
Specifically, the discontinuity represented by the end of the crust and the passage to the upper mantle is the Mohorovicic discontinuity, or as it is briefly called the Moho.
The depth at which it is found varies greatly because the thickness of the crust is very different depending on whether it is oceanic crust (about 7 km) or continental crust (up to 100 km under the great mountain ranges).

Explanation:
Answer:
Transport of sediments causes them to become rounder as their irregular edges are removed both by abrasion and corrosion. Beach sand becomes highly rounded due to its endless rolling and bouncing in the surf.
