Oceanic crust also called sima from silicon and magnesium and continental crust sial from silicon and aluminium. Many of the mountains and some of the valleys in southern california were formed by the san andreas fault system the tectonic boundary between the pacific and north american tectonic plates which runs to the east of san diego county from the gulf of california up through the salton sea and into the los angeles region. A map of global tectonic and volcanic activity over the last one million years showing.

Active ridges continental extensions transform faults ridge spreading rates and directions continental rifts subduction and overthrust zones and generalized volcanic activity. Geological survey map of tectonic plates show 21 of the major plates as well as their movements and boundaries.

It is the longest. The earth s plates jostle about in fits and starts that are punctuated with earthquakes and volcanic eruptions. As they move only inches every year and depending on the direction of that movement they collide forming deep ocean trenches mountains volcanoes and generating earthquakes. The concept of plate tectonics was formulated in the 1960s.
