Question

1. what type(s) of wave travel as a transverse wave? *

primary wave
secondary wave
surface wave
primary and secondary wave
primary, secondary, and surface wave

1. what type(s) of wave originates at epicenter? *

primary wave
secondary wave
surface wave
primary and secondary wave
primary, secondary, and surface wave

Explanation:

For question 7: Secondary waves are transverse (particles move perpendicular to wave direction), primary waves are longitudinal, and surface waves have a transverse-like component but secondary waves are the definitive transverse body wave.
For question 8: All three wave types (primary, secondary, surface) originate at the earthquake's epicenter, as the epicenter is the point on the Earth's surface directly above the focus where all seismic waves are generated and radiate outward from.

Answer:

1. Secondary Wave
2. Primary, Secondary, and Surface Wave
