What does the Moho discontinuity indicate?

The Moho is the boundary between the crust and the mantle in the earth. This is a depth where seismic waves change velocity and there is also a change in chemical composition. Also termed the Mohorovicic’ discontinuity after the Croatian seismologist Andrija Mohorovicic’ (1857-1936) who discovered it.

What is the importance of Moho discontinuity?

The Mohorovicic discontinuity is important because it marks the boundary between the mantle of liquid magma and the hardened magma that forms the curst.

What is Moho discontinuity and who discovered it?

The Mohorovicic Discontinuity was discovered in 1909 by Andrija Mohorovicic, a Croatian seismologist. Mohorovicic realized that the velocity of a seismic wave is related to the density of the material that it is moving through.

Why does Moho affect the velocity of the seismic waves?

Seismic waves move more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.

Where is the Moho discontinuity?

The Mohorovicic discontinuity (the Moho) is the boundary lying between the crust and the mantle of the earth across which seismic waves change velocities. This boundary is located approximately 24 miles below the earth’s surface and 6 miles below the oceanic floor, a distance which varies from place to place.

What is the meaning of Moho?

Definition of Moho

: the boundary layer between the earth’s crust and mantle whose depth varies from about 3 miles (5 kilometers) beneath the ocean floor to about 25 miles (40 kilometers) beneath the continents.

What is the Moho discontinuity made of?

As you probably know, the Mohorovicic Discontinuity is the boundary of the earth’s crust and the mantle. It would be made of elements such as oxygen, iron, sodium, silicon, and aluminum, among others. These elements would be present in rocks that make up both the Earth’s crust and mantle.

Is the Moho discontinuity solid or liquid?

The Mohorovicic Discontinuity is a discontinuity in the composition of solid rock, but it is indeed solid on both sides.

How does the Moho relate to the asthenosphere lithosphere?

How does the Moho relate to the asthenosphere lithosphere? The MOHO is a place where seismic P-waves suddenly increase in velocity, presumably because they are able to travel faster through the denser mantle rocks. … The MOHO is NOT the lithosphere-asthenosphere boundary. Rather, the MOHO is the crust-mantle boundary.

What is the Moho model in occupational therapy?

The Model of Human Occupations (MOHO) is a model that describes how humans generate and modify their occupations in interaction with environment, which presents a dynamic open cycle system of human actions.

How does MOHO define healthy or optimal functioning?

According to MOHO, when the human open system is functioning optimally, order exists within the system. Function is displayed when (Kielhofner defines function as order): Individual competently performs everyday tasks of daily life in a routine and satisfying way. “Order” produces and maintains a state of health.

What does the MOHO theory consider human beings?

MOHO is a client-centered model that is grounded in occupational therapy practice. The model views human beings as dynamic systems that interact with their environment. Human behavior is a result of interactions between inherent human elements and environmental influences.

What is the goal of MOHO?

MOHO is an occupation-focused framework that aims to explain aspects of engaging in occupations and how illness and disability related problems arise. MOHO is said to be client-centred, evidence based and holistic in nature.

How is MOHO used in practice?

More than 80% of respondents indicated that they used MOHO in their practice at least some of the time. Therapists reported that MOHO supports holistic, occupation-focused, client-centered, and evidence-based practice. They reported finding MOHO concepts useful for treatment planning and intervention.
