Started at 4,500 Ma 15. Which of the following represents the longest duration of geologic time? a) Jurassic b) Precambrian c) Paleozoic d) Mesozoic e) Cenozoic 16. If a description of sediment states that it contains large, angular fragments that are mostly red in color, what type of data would this represent? a) qualitative b) quantitative c) numerical d) measurement 13. Which letter on the accompanying figure indicates the elevation? a) A b) B e) c d) D 17. What type of rock is shown in this photograph? a) crystalline rock b) clastic rock c) rock with minerals that are too small to see none of these d)Explanation / Answer
11) The oldest unit of figure is 4. (5 is not oldest because it intruded later and cut the 4, 3, 2, 1 layers)
12) The type of map is topographic map with contours.
13) B indicates the elevation. Because elevation is height above the sea level.
14) B subdivision indicates Mesozoic timescale. Because The Mesozoic Era is divided into three time periods: the Triassic (251-199.6 million years ago), the Jurassic (199.6-145.5 million years ago), and the Cretaceous (145.5-65.5 million years ago)
15) Precambrian represents the longest duration of geologic time.
16) If a description of sediment states that it contains large, angular fragments that are mostly red in color, then the type of data is qualitative. Because qualitative describing the quality of something in size, appearance, value, etc.
17) The photograph may be clastic rock. (Please give clear photo, it is small. I can not see it properly. when i zoom the photo, it becomes hazy. Please give clear picture.)
