Based on the theory that focuses on wellness and prevention of disease, b. List the order of lettered events from oldest to youngest. Step 3: List the letters in the order in which they occurred. The time that could have been represented by such layers is instead represented by the disconformity. Help us work out the relative ages of the layers of sedimentary rocks, from youngest to oldest. The youngest fossil is the Foraminniferan. g) If an x mark appears, you have incorrectly placed a rock layer. You will get brainliest geologists can determine the relative ages of sedimentary layers by using the law of superposition. From oldest to youngest, these are the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. It is therefore younger than B-F. Fill the blanks with the words/ phrases that best complete the sentences.choices cross-cuttingerosionextrusivefaultintrusionsedimentarystratificationsuperpositionunconformityyounger1. Layer B formed. The photo of the Grand Canyon here show strata that were originally deposited in a flat layer on top of older igneous and metamorphic basement rocks, per the original horizontality principle. 1. layer k is the oldest. Think about the principle of cross-cutting relationships. Superposition and cross-cutting are helpful when rocks are touching one another, but are useless when rocks are kilometers or even continents apart. Second, we observe that rock layer H (which is an igneous intrusion) cuts into rock layers B-F. then the ships brought sugar to north america, to be sold or turned into rumwhich the captains brought back to europe. As you can see in the diagram, fault Q does not cross layer K. It stops right under it, so this means that the fault occurred first, then over a span of time, layer K was deposited. Layers of sedimentary rock extend sideways in the same order. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Line T represents a fault line. Volcanic ash flows are often useful as key beds because they are widespread and easy to identify. In the lowest parts of the Grand Canyon are the oldest sedimentary formations, with igneous and metamorphic rocks at the bottom. Arrange the rock layers from oldest to youngest - Brainly.ph Relative rock layers Science Learning Hub Like taco shells that start out as flat tortillas, rock layers can bend or even fold over. which statement describes the geologic features? The final events affecting this area are current erosion processes working on the land surface, rounding off the edge of the fault scarp, and producing the modern landscape at the top of the diagram.
