What do vertical and horizontal surface waves have in common?
- both waves travel along earth's surface and decrease in amplitude with depth below the surface.
- both waves travel within earth and increase in amplitude with depth below the surface.
- both waves travel along earth's surface and increase in amplitude with depth below the surface.
- both waves travel within earth and decrease in amplitude with depth below the surface.

Option A

Both waves travel along earths surface and decrease in amplitude with depth below the surface.

Explanation:

The vertical surface waves have a characteristic of traveling along the earth surface and as they go deeper below the earth's surface their amplitude decrease. Similarly, the horizontal surface waves also travel along the earth surface and experiences a decrease in amplitude as they travel deeper below the surface of the earth.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.
