Question 150385
Granire is an igneous rock with a coarse grain. In one sample analyzed for grain size, the average grain size was 0.938 mm. In another sample from a different location, the average grain size was found to be 1.2 mm. What is the difference between the two average grain sizes?
--------------
difference = 1.2 - 0.938 = 0.262
