(For example, if you believe that the position of the igneous rocksurrounded by shale is an example of superposition, you would state, “Theprinciple of superposition is illustrated where the igneous rock lies withinthe shale.”) Apply the principles of relative ages to put the five labeled features in order of theirformation. Note that letter "D" is pointing to a fault.Oldest feature: A2nd oldest feature: BMiddle age feature: D2nd youngest feature: EYoungest feature: CWhich rock unit would be most likely to exhibit contact effects?ShaleWhich rock unit is most likely to contain pieces of an older rock? (Two possible answers.)Igneous rockE was in place (oldest feature) before being broken, or or cross-cut, by fault D. A magmabody then cut across E and D and cooled to form layer C. Weathering left an unconformity,or erosional surface, B. You can tell that this happened after C because parts of C havebeen eroded away. The sedimentary layers contained in A were the last (newest) to form inthis diagram.Describe at least two examples of how you could use the principle ofcrosscutting relations to identify the relative age (older/younger) ofdifferent rock units.The age of the igneous rock is always younger than the rock it cuts into. Igneous rock insideof limestone will be younger, whatever the age of the limestone is, the igneous rock shall beyounger. That is also applicable in regards to faults, which is a structure relationship. The principle of superposition is illustrated where the igneous rock lies within the limestoneQuestion 3Correct1.00 points out of1.00FlagquestionYou are logged in as Jonathan Kluger (Log out)Answers will vary, but may look something like the following:I could use the principle of crosscutting relations to identify the relative age of different rockunits by, for example, observing that many rocks (such as limestone) are often crosscut byjoints and faults; based on the principle of crosscutting relations, the limestone must be olderthan the fractures that cut across it. Additionally, dikes, sills, and veins can cut acrosspreexisting, older rock units, which further shows crosscutting relations; an example of this iswhen dikes of granite can intrude into older igneous rock.Comment:Explain more about the relationships associated with faultsThe statement below (in quotes) originated from an observation by one ofthe first geologists, James Hutton. Hutton's interpretation of an outcropalong the coast of Scotland has come to represent a basic concept that isapplied to unraveling Earth's history."Understanding geologic processes active in themodern world is crucial to interpreting Earth’s past.”What is the name of this concept?Select one:a. Superpositionb. Uniformitarianism c. Cross-cutting relationshipsd. Index fossilse. Original horizontalityThe correct answer is: UniformitarianismFinish
