Have you ever walked around your community and noticed a giant crack on the road? That could possibly be a fault, which might be similar to the 1,200-mile-long (1,931 km) San Andreas Fault line in California.

You may wonder how these fault lines are created. The Earth has different tectonic plates (like the Pacific Plate for Example) which may be prone to some imbalance and with some stress can shake and move against other tectonic plates, which would cause earthquakes and would create some fault lines.

The state of California is known for having many earthquakes which resulted in the 1,200-mile-long San Andreas Fault which runs through California. It is the longest fault in North America.
