               the two solar energy advantages are that solar energys fuel is free, and it is non-polluting.
            -nuclear energy
              the uranium nuclei split into smaller nuclei snd get neutrons , also heat energy.
            -wind energy

week 12: Earthquakes

The difference between the focus and the epicenter of an earthquake is that a focus is the point where the rock first fractures during an earthquake and the epicenter is the point on the surface directly above the focus.

The "p"  on the seismograph is the primary wave and it moves in a compressional motion it is an elastic wave.
the "s" on the seismograph is the secondary wave moves in a shear motion perpendicular to the direction the wave is travelling it is also a seismic body wave that shakes the ground back.
They are different because the S wave moves much slower than the P wave.
