Answer to Problem 10RAT

The correct option for the statement “The birth of San Andreas Fault corresponds to” is option (b).

Explanation of Solution

The collision that began in the late Mesozoic continued till Cenozoic, which led to the formation of the Sierra Nevada and Andes Mountain. Moreover, off the western coastline of North America, a mid-ocean ridge was generated in the Pacific Ocean, which is known as Pacific Ridge System. The San Andreas Fault was formed by the collision of the boundaries of Pacific Ridge System and North America plates. Both the plates move to meet in the western California part, which causes an earthquake along the fault. This was about 30 million years ago in California, which affects most of California’s populated area. This continental fault extends up to 1200 km, through California.

Conclusion:

Therefore, the correct option for the statement “The birth of San Andreas Fault corresponds to” is option (b).
