What is the thickest interior layer of Earth? The thinnest?
Expert Solution & Answer
To determine
The thickest and the thinnest interior layer of earth.
Explanation of Solution
Introduction:
Measuring the thickness of different layers of the earth is possible as all layers have different properties. This is the reason due to which during earthquake waves travel with different velocities in each layer of the earth. When the wave enters another layer, then due to the change in the denseness of the medium, refraction of seismic wave takes place which makes it possible to know the thickness of the layer indirectly.
In general, the earth is known to have
The mantle is the layer next to the earth’s crust layer, and it covers approximately
Conclusion:
Therefore, Earth’s crust is the thinnest layer and mantle is the thickest one among all the layers.
