Responses

Both waves cause earthquakes.
Both waves cause earthquakes.

Both waves move the ground in the direction they travel.
Both waves move the ground in the direction they travel.

Both waves occur in the ocean.
Both waves occur in the ocean.

Both waves move the ground perpendicular to the direction they travel.

Answer 1

The correct option that describes both p-waves and s-waves is:

**Both waves cause earthquakes.**

P-waves (primary waves) and S-waves (secondary waves) are both types of seismic waves generated by earthquakes. The other options do not accurately describe both types of waves. For instance, p-waves move the ground in the direction they travel, while s-waves move the ground perpendicular to the direction they travel. Additionally, while these waves can be recorded in some cases related to the ocean (such as tsunamis), they are not exclusively associated with the ocean.
