What are Earth’s core and mantle made of? Explain how we know.
An earthquake occurs 6,875 km from a seismograph. The P-waves arrive 11.6 minutes later. How fast is the P-wave traveling (in km/s)? If the lag time between P- and S-waves is 10.8 minutes, how fast are the S-waves traveling (in km/s)? Using the shadow of S-waves you determine that the radius of the core is 55% of the Earth's 6,378-km radius. How many kilometers from the surface is this (in km)? To calculate how fast the P-waves are traveling, we need to divide the distance the waves travel by the time. vP = d s vP = km/s
Tutorial An earthquake occurs 7,375 km from a seismograph. The P-waves arrive 12.2 minutes later. How fast is the P-wave traveling (in km/s)? If the lag time between P- and S-waves is 10.6 minutes, how fast are the S-waves traveling (in km/s)? Using the shadow of S-waves you determine that the radius of the core is 55% of the Earth's 6,378-km radius. How many kilometers from the surface is this (in km)? Part 1 of 3 To calculate how fast the P-waves are traveling, we need to divide the distance the waves travel by the time. d Vp = Make sure you are dividing by the time in seconds. s Vp = Make sure you are dividing by the time in seconds. km/s
