Not all are activeCurrent LectureTransform boundaries are plate boundaries that move past each other. In these spots there are earthquakes sometimes up to magnitude sevens. However, these are the only boundaries that have no volcanoes. One example of this is the San Andreas Fault in the southwest corner of the These notes represent a detailed interpretation of the professor’s lecture.

The pacific plate and North American plate are slowly sliding past each other.Hot spots are stationary points in the earth where heat is rising. The heat is coming from the earth’s core. What happens is a lot of volcanoes in subduction zones erupt. Subduction zones are zones where one plate is subducting. The youngest volcanoes are closest to the hot spot, with the youngest being right on top of it. The older volcanoes are not
