They have the ultimate responsibility for making sure the work environment is healthy and inclusive, and for preventing and addressing discrimination and harassment.They must make sure that their workplaces are free from discriminatory or harassing behaviour.Figure 6.2 Uplifted and tilted sedimentary strata in the Canadian Rockies. Assume the playing cards shown in Figure 6.3 are layers of sedimentary rocks viewed from above. In the space provided in Figure 6.3, list the order, first (oldest) to last (youngest), in which the cards were laid down. Were you able to place all of the cards in se- quence? The rock mass adjacent to the one containing the inclusions must have been there first in order to provide the rock frag- ments. Figure 6.9 is a geologic cross section showing sedi- mentary rocks (A, B, D, E, F, and C), an igneous intru- sive feature called a dike (C), and a fault (H). The three rocks, Rocks 1, 2, and 3, illustrated below the layered sequence were found nearby and each rock contains the fossils indicated. pp ymg p P cate the proper position of each of the three rocks Petrification: The small intemal cavities and pores of the original organism are filled with precipi- tated mineral matter. Quest Figure 6.12 Geolo in block diagram of a hypothetical area showing igneous intrusive features (K and L). Figure 6.12 is a geologic cross section of a hypo- and thetical area. Explain why it was difficult to place the fault, let- in the cross section, ter M, in a specific position among the sequence f ts ‘ F'gure 6.12. Ultimately, this process of decay produces an atom that is stable and no longer radioactive.If not, which one(s) could not be ”rela- tive” dated and why? Of the two sequences of rocks, A—D and E~G (A—D, E—G), was disturbed by crustal move- ments after its deposition. What law or principle did you apply to arrive at your answer? Apply the law of superposition to determine the relative ages of the undisturbed sequence of sedi- mentary rocks. Therefore, the rock containing the inclusions is the younger of the two.

For exam- ple, eventually the stable atom lead-206 is produced from the radioactive decay of uranium-238.The grade for this chapter can come solely from the end of chapter test.

Although geologic processes such as erosion, deposition, and volcanism are governed by these unchanging laws, their rates and intensities may vary. However, if the sedimentation process is suspended by an emergence of the area from below sea level, then no sediment will be deposited and Figure 6.5 Inclusions are fragments of one rock enclosed within another. Such a gap in the rock record is termed an unconformity. hon-m sedimentary — rocks -------- _----—--I‘ —‘~— -Vv—N ‘ '. As rocks form, they often incorporate the preserved remains of these organisms as fossils. the mineral quartz now occupies the internal spaces of what was once wood. is the replica of fish after the carbonized remains were removed. mineral matter occupies the hollow space where a shell was once located. is a track left by a dinosaur in formerly soft sediment. l - Cast: The space once occupied by a dissolved shell or other structure is subsequently filled with mineral matter.

If a geologist claims to be 45 years old, that is an absolute age.

Superposition: The most basic concept used in relative dating is the law of superposition.

Because of this, we tend to think that 80 years is a very long time. 2 Peter 3:8 says that a thousand years to God is like a day.

  1. This is a simple feature that generates questions and quizzes to determine the compatibility of a user to another. Nevertheless, it is a great site for lovers of music, concerts and organists. It is your go to site when you want to meet people with whom you share the love of music. The only difference is that Passion Network has more specific niches (over 250 unique dating niches).
