Document Summary
Earthquakes learning goals: describe the global distribution of earthquakes and how often quakes of various magnitudes occur. Earthquakes occur where tectonic plates are colliding or moving apart. They do not occur with equal likelihood everywhere, but do seem to occur in specific areas more often. Larger earthquakes occur to the west of vancouver island. Earthquakes can have negative value because of magnitude is in logarithmic scale, basically before converting the value was between 0 and 1. Seismogram is a graph which measures ground motion related to time. Majority of the earthquakes occur at the margins of tectonic plates. Largest occur where oceans meet continents: understand the different types of faulting at the plate boundaries, and which plate boundaries produce the largest quakes. There are 9 major plates in lithosphere, there are two types of plates: oceanic plates and continental plates: oceanic plates are fast-moving, centimeters per year, and young,
