Is it true that the closer an earthquake the greater the time difference between the arrival of P-waves and the arrival of S-waves?

False. The closer you are to the epicentre, the smaller the time difference between the arrival of P and S-waves.

What happens to The difference in arrival times between p waves And s waves as The distance From the earthquake increase?
The difference between the arrival times increases as the distance from an earthquake epicentre increases as S-waves travel more slowly than P-waves so the greater the distance the further they lag behind.
How much greater is a magnitude 7.0 earthquake over a 6.0 earthquake?
10 times larger
In what way is the time difference between the arrival of p waves an s waves at the seismograph station like the time difference between a lightening flash and thunder?
The difference in arrival of P and S waves on a seismogram tells seismologists how far away the away the source of the quake is from the recording station. A little more detail! P-waves travel more quickly through the Earth than S-waves. As such the further away the seismometer is from an earthquake epicentre the greater the amount of distance the S-waves lag behind the P-waves. The same is true for lightning. The flash is visible light which is a form of electromagnetic wave and travels so quickly (approx. 300x106 m/s) that you see it (at what may as well be described as) instantly. However sound waves travel much more slowly (approx. 330 m/s in air), roughly a million times slower than light. As such there is a significant lag time between seeing the flash and hearing the resultant clap of thunder.
When an earthquake occurs is shaking greater?
Yes, shaking is a primary characteristic of earthquakes
How much more powerful is a 9.0 earthquake and a 7.0 earthquake?
a. Shaking amplitude => 10^9/10^7 = 100 times greater. b. Energy release => (10^9/10^7)^(3/2) = 1,000 times greater.
What is the difference in arrival time between P and S waves equivalent to?
This value is related to the distance of the seismometer station from the earthquake's epicentre. The larger the difference in arrival times, the greater the distance.
What happens to The difference in arrival times between p waves And s waves as The distance From the earthquake increase?
The difference between the arrival times increases as the distance from an earthquake epicentre increases as S-waves travel more slowly than P-waves so the greater the distance the further they lag behind.
Is it true or false that the closer an earthquake the greater the time between the arrival of P waves and the arrival of S waves?
true
How much greater is a magnitude 8 earthquake than a magnitude 4 earthquake in amplitude?
The Richter magnitude scale is a base-10 logarithmic scale of the shaking amplitude. This means that a difference of 1 in the scale is equivalent to a 10-fold increase in amplitude. So the difference in amplitude between a mag 8 and a mag 4 earthquake is 104.
The greater the electronegativity difference between two bonded atoms the greater the percentage of?
The greater the electronegativity difference between the two bonded atoms, greater is the ionic character of the bond.
What is the difference between better and greater?
better is goodx2 greater is betterx2
Is data about an earthquake from two seismographic stations enough information to locate the epicenter?
From Science Explorer Prentice Hall Earth Science: " Geologists use seismic waves to locate an earthquake's epicenter. Seismic waves travel at different speeds. P waves arrive at a seismograph first, with S waves following close behind. To tell how far the epicenter is from the seismograph, scientists measure the difference between the arrival time of the P waves and S waves. The farther away an earthquake is, the greater the time between arrival of the P waves and the S waves." Did this help?
Why does the time between the arrival of the P wave and the S wave become greater and greater as you get farther away from the epicenter?
It is because the epicenter decreases their strenght as it is closer to it
A seismograph station can determine its distance from an earthquake's epicenter by .?
P-waves and S-waves are released by an earthquake at the same time and travel out from the epicentre in all directions. However P-waves travel faster than S-waves so the further away from the earthquake's epicentre the greater the lead the P-waves have on the S-waves. Observation of the seismogram trace at the seismometer station will allow the scientists to find the P-wave and S-wave arrival times and measure the difference between them. As the P-waves are faster they always arrive first (hence their name - primary wave). The greater the difference between the time that the P-waves and S-waves first arrive (i.e. the greater the lead the P-waves have), the further the distance to the epicentre. They are able to use the time difference along with an estimate of the speed of the P-waves and S-waves to find the distance from the station to the earthquakes epicentre.
