This are not correct Determine which of the following statements about unconformities are Trueor False.Unconformities involve younger sediments or sedimentaryrocks that overlie significantly older rocksTrueNonconformities involve younger sediments or sedimentaryrock that rest depositional on older plutonic (i.e., intrusive)rocks and/or metamorphic rocks, both of which wereTrueformed in an environment beneath the surface of the earth.It's important for geologists to be able to recognizeunconformities because they tell us that the rock unitsinvolved do not represent a complete record of geologicFalseevents that occurred during the time when the rocks orsediments formed.FalseNonconformities are a type of unconformityOf all the types of unconformities, disconformities areFalse'usually the easiest type to identify because the sediments orsedimentary rocks on either side of the contact are usuallytilted in different directions.

Determining the age of any layers or rock beds, there are two ways from which we can understand the age of the sample one is the relative age by comparing lithology to the other lithology (like fossils) and another is the absolute dating (radioactive study, it is the study of the sample by the radioactive sample where one calculates the decay rate of the sample). The study of the rock unit age is known as geochronology where scientists try to find out the absolute and relative age of the rock unit. There are different principles for understanding the relative age of the rock unit. These methods help geologists to understand past deposition.Unconformities involve younger sediments or sedimentary rocks that overlie significant older rocks- this is true as the unconformities are the layer of nondeposition where there was no deposition and this boundary differentiates the older layer from the younger layer. Nonconformities involve younger sediments or sedimentary rock that rest depositional on older plutonic (i.e., intrusive) rocks and/or metamorphic rocks, both of which were formed in an environment beneath the surface of the earth- this is false because nonconformity involved the younger layers as a sedimentary layer and the older layer which could be the metamorphic or igneous origin and because the sedimentary rocks deposit only on the surface. It's important for geologists to be able to recognize unconformities because they tell us that the rock units involved do not represent a complete record of geologic events that occurred during the time when the rocks or sediments formed- this is false because the unconformity layer represents the geological events. Nonconformities are a type of unconformity- this is true because nonconformity refers to the unconformity surface where the geological formations, essentially sediments, are deposited on top of an eroded or unconformity surface of igneous or metamorphic rock formations. Of all the types of unconformities, disconformities are usually the easiest type to identify because the sediments or sedimentary rocks on either side of the contact are usually tilted in different directions-this is false because tilted layers are present in angular unconformity not in disconformity.
