Final answer:
The Mohorovičić discontinuity, or the Moho, is a boundary between the Earth's crust and the mantle. It marks the transition from the rigid crust to the more ductile mantle below. The Moho plays a crucial role in studies related to plate tectonics, earthquake dynamics, and the overall understanding of the Earth's interior.
Step-by-step explanation:
The Mohorovičić discontinuity, also known as the Moho, is a boundary between the Earth's crust and the mantle. It was discovered by Croatian scientist Andrija Mohorovičić in 1909. The Moho marks the transition from the rigid crust to the more ductile mantle below.
At the Moho, there is a significant increase in seismic wave velocities, which indicates a change in the composition and physical properties of the Earth's interior. This boundary is not continuous but occurs at different depths and angles of inclination worldwide. It is typically found at depths between 5 and 70 kilometers below the Earth's surface.
The Mohorovičić discontinuity is an important feature in understanding the structure and composition of the Earth. It plays a crucial role in studies related to plate tectonics, earthquake dynamics, and the overall understanding of the Earth's interior.
