Carbon is allowed to diffuse through a steel plate 15mm thick. The concentrations of carbon at the two faces are 0.65 and 0.30 kg C/m3 Fe, which are maintained constant. If the pre-exponential and activation energy are 6.2×10-7 m 2 /s and 80,000 J/mol, respectively, compute the temperature at which the diffusion flux is 1.43 …

Notice the two red lines, one labeled O and the other labeled G. These lines indi- cate the times at which two different trilobite species (Olenellus and Glossopleura) lived, along with their geographic distribution. These trilobites are index fossils or indicators of very specific intervals of geologic time. Olenellus lived during the Early Cambrian and Glossopleura lived during the Middle Cambrian. These red lines can be considered time lines. 6. What is the age of the Bright Angel Shale in the western part of this diagram? 7.
