Today I visited San Francisco in the Golden State. The picture is the Golden Gate Bridge and on average, over 120,000 people cross this bridge per day! I drove over the bridge and also went through the city on a cable car! It was super fun!
There was a tour guide on the cable car and he started talking about how they experience some earthquakes. I asked him why and he said because of a transform boundary. The San Andreas fault (where the Pacific plate is grinding against the North American plate) goes through 2/3 of California. That's why there was a huge earthquake in San Francisco in 1989. The plates are rubbing against each other and they eventually get "locked" in place. The plates keep trying to move but they're locked so the pressure keeps building up more and more. Eventually, the plates break off and cause a huge amount of seismic activity. Well I'm off to somewhere else now! Bye!
