If the speed of the wave changes, then the ______ changed.

There are two types of seismic waves: P-waves and S-waves.

Groups:

(a) P-waves

,

(b) S-waves

• solids only

• transverse

• liquid and solid

• fast

• longitudinal

• slow

The first table is about the​ (a)   wave and the second table is about the​ (b)   wave.

Overall, as the depth increases, speed​ (c)  

• P
• S
• increases.
• decreases.
• stays the same.

Overall, the speed of the wave is increasing. Sometimes, however, the speed decreases or stays the same. Highlight the lines between depths where you see changes in the pattern in the speed of the wave.

Ex: increasing, increasing, DECREASING or increasing, increasing, STAYS the SAME

You should highlight 3 lines in the p-wave chart and 2 lines in the s-wave chart.
