1. what is the difference between P waves and S waves? 2. How do you determine the difference between when a P wave and an S wave arrives at a seismogram location?

P waves travels faster than S waves.

Explanation:

P waves travels faster than S waves.  It can travel through any kind of material but s waves only travel through solid medium.  P waves are smaller in size than s waves.  P waves are the first waves to hit seismographs while the s waves are the second wave arrive at a seismogram location, so we can say that the wave which reach first at a seismogram location is the P waves. The speed of the wave shows which wave arrive first at a seismogram location.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
