Chapter 26, Problem 13RQ

Are folded rocks primarily the result of compressional or tensional forces?

To determine

Whether the formation of folded rocks is primarily compressional forces or tensional forces.

Answer to Problem 13RQ

The folded rocks are primarily results of compressional forces.

Explanation of Solution

The outermost part of the Earth is known as the lithosphere. This outermost part is divided into tectonic plates. When tectonic plates are pushed together due to the Earth’s internal activities, it will result in compressive action between plates.

The compression of the plates results in the compression of the rock that is present on the outermost part of the Earth. Due to this compression, the bending occurs in the rock and the formation of folded rocks takes place.

Conclusion:

Therefore, the folded rocks are primarily results of compressional forces.
