Choose the correct statement about earthquake waves.
seismic waves inside earth travel only in straight lines. seismic p‑waves travel throughout the planet and s‑waves are blocked by earth's liquid core. both p‑waves and s‑waves travel at the same velocity, which does not depend on the density of material through which they are traveling. the vibrations in the p‑waves and s‑waves create gravitational waves. a richter scale is a scientific machine used to measure earthquakes.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
