Volcanic rock is found to have a ratio of parent K-40 to daughter Ar-40 of
1/7.
What is the minimum age of the rock? The half-life of K-40 is 1.3 billion years.
The asthenosphere lies just below the

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.

- Suppose a team of scientists is studying the formation of an island chain generated by four extinct volcanoes. To determine when each volcano became extinct, the scientists calculated the age of the youngest layer of igneous rocks on each island. After a recent research trip, the identifying tag of a sample rock was lost. The scientists ask you to help identify the sample rock's parent volcano. The scientists give you some information. 1) The initial ratio of strontium-87 to strontium-86 in the rock was 0.7129. 2) The decay constant, 1, for rubidium-87 is 1.42 x 10-1!. 3) The current isotope concentrations in the rock are 8" Sr = 126 ppm, 8'Rb = 218 ppm, and 8ºSr = 175 ppm. %3D Use the isochron equation to calculate the approximate age of the mystery rock. 87.
