3. Causes of earthquake
earthquakes are caused by faulting, the rock sudden
movement.("Reply to ASK-AN-EARTH-SCIENTIST." The Causes of Earthquakes. N.p., n.d. Web. 07 Mar. 2015.

4. • P-waves That are longitudinal in nature, it's faster than other waves.
• S-waves That are transverse in nature, it's the faster-moving P-waves and
displace the ground perpendicular to the direction of propagation.
• L-waves It's similar to the S-wave, but it's more save than that.

• Earthquake is very dangrous it can effect many people die and
brooken the house.

8. Summary
• The earthquake is cause the faulting, and the rock
movement. When the earthquake are happen, it will
make the seismic waves, seismic waves have 3type of
them, that are P-wave, S-wave and L-wave. Earthquake
can also effect the tsunami, tsunami is when earthquake
are happen under the sea. Earthquake and tsunami are
both dangrous.
