California sits at the border between two major tectonic plates: - Pacific plate, moving northwest, - North American plate, moving southeast. Each year the California area has about 10,000 earthquakes. Which of the following describes why earthquakes are a common occurrence in California?

• The two plates form a transform boundary because earthquakes are caused by plates sliding past each other.
