Question

a ghoul hears \surface waves\ rattling tombstones. where do those travel?
through earths core
only through solids
along earths surface
through the mantle

Explanation:

Surface waves in seismology travel along the Earth's surface. They are different from body waves (which travel through the Earth's interior like core or mantle). The option "Along Earth’s surface" matches this definition. Other options: "Through Earth’s core" and "Through the mantle" are for body waves (like P and S waves), and "Only through solids" is not accurate for surface waves (they travel along the surface, not restricted to solid - like in the context of Earth's layers, surface waves move on the crustal surface).

Answer:

C. Along Earth’s surface (assuming the green option is labeled C; if the original labels were different, adjust the label but the text is "Along Earth’s surface")
