whats first and last
1.primary
2.secondary
3.seismic
thanks
primary waves arrive first. then secondary. then seismic. seismic also does the most damage.
which cause more damage during an earthquake
oh ok
the Water Resource Challenges table in Appendix E by briefly identifying three fresh and three ocean water resource issues. Then, respond to the questions provided at the bottom of Appendix E.

The seismic wave that arrives first at a seismograph station is called the P-wave (Primary wave), also known as the compressional wave. P-waves are the fastest seismic waves and can travel through solid rock, liquid, or gas. They are the first to be detected because they compress and expand the material in the same direction they travel, causing a push-pull motion.
The seismic wave that arrives last at a seismograph station is called the S-wave (Secondary wave), also known as the shear wave. S-waves are slower than P-waves and can only travel through solid material. Unlike P-waves, S-waves move the material perpendicular to their path, causing a shaking motion.
Regarding the seismic waves that cause most of the damage during an earthquake, it is the surface waves. Surface waves are slower than both P-waves and S-waves but have larger amplitudes. There are two types of surface waves: Love waves and Rayleigh waves. Love waves move the ground from side to side, while Rayleigh waves move the ground both vertically and horizontally in a rolling motion. These surface waves can generate strong shaking and cause the most destructive effects, such as surface rupture, ground displacement, and building damage.
