Chapter 26, Problem 9TE

To determine

The reason for the Earth’s crust being thicker beneath a mountain range.

Answer to Problem 9TE

The Earth’s crust is thicker because of the mountain building measure where one plate subducts under another, inspiring the lighter, less thick plate.

Explanation of Solution

The Earth's crust is thickened by the compressive forces identified with subduction or mainland crash. The buoyancy of the crust drives it upwards, the forces of the collisional stress adjusted by gravity and disintegration. These structures, a mountain root underneath the mountain range, which is the place of the thickest crust, is found.

The thinnest outside layer is found in crack zones, where the covering is diminished by separation faulting and, in the end, cut off, supplanted by the maritime crust. The tallness of mountain ranges is normally identified with the thickness of the outside layer.

Conclusion:

Therefore, the Earth’s crust is thicker because of the mountain building measure where one plate subducts under another, inspiring the lighter, less thick plate.
