This is the story of how plates move when energy is released
From the University of Singapore!
What is the difference between body waves and surface waves? And between P-waves and S-waves?
Body waves travel through the interior of the Earth. On the other hand, surface waves propagate only at the interface between two different media, like the interface between Earth and atmosphere (i.e. the surface of the Earth).Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves).P-waves are compression waves. They can propagate in solid or liquid material S-waves are shear waves. They only propagate in solid material. By studying the trajectories of S-waves, scientists could prove that the Earth had a liquid outer core.
1. Comparing seismic activity as waves (SPL) 2. Why graph seismic activity as time verse distance? ( An online assignment) · It allows us to calculate epicenters of earthquakes! (http://home.wlu.edu/~kuehns/VirtualEarthquake.pdf · http://regentsprep.org/regents/earthsci/eqwaves.htm · http://www.oakton.edu/user/4/billtong/eas100lab/lab10quake.htm (Select one of the three and put into duotang)
3. Lets simplify.. · Primary waves “push”. They are compression waves and are the fastest waves. · Secondary waves “sway sideways”. They are transverse waves. They are the second fastest. · L waves are like ripples on an pond. They cycle and are the slowest and yet the most dangerous. L for long time…longitudinal..late..and only occurring on surface of earth.

Volcanism or Vulcanism..but no Mr Spock
This is the story of magma moving through plates Some questions to consider · How are volcanoes formed and how many types are there? · What is the affect of volcanoes on the weather and climate? · How have volcanoes affected world civilizations? A detailed explanation http://www.britannica.com/science/volcanism

How do we compare volcanoes to earthquakes?
Well both will generally affect your day..
Earthquakes are events occurring due to shifting of plates. Volcanoes are magma moving and then being released between plates.
