Aseismograph station can determine its distance from an earthquake's epicenter by 1. subtracting p from s wave arrival time and then determining what that time is equal to in distance 2. mapping p and s wave arrival times on a map 3. subtracting p, s, and l wave arrival times, determining distance from this number, and then mapping it 4. one station can't locate its distance from an epicenter. three stations must do this.

A seismograph station can determine its distance from an earthquake's epicenter by mapping P and S wave arrival times on a map. This distance is called s-p interval. It is the distance between 1st p wave and the 1st s wave tells you how many seconds the waves are apart .

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
