The principle of superposition explains the idea that ______ layers of rock, along with the fossils they contain, are older than the layers ______ them.Multiple choice question.lower; belowdarker; lighter thanhigher; belowlower; above

Which principle tells you how rock layers are laid?A.UniformitarianismB.Faunal successionC.Correlative datingD.Original horizonality

Which statement explaining the age of the rock layers best supports the answer to Part A?​   ARock layers that contain fossils are always the oldest rock layers and can be used to determine the ages of rock layers above them.BGeologic events like earthquakes can erase rock layers from the geologic timescale and make it difficult to know the ages of different rock layers.COlder rock layers will always be directly below younger rock layers unless they have been disturbed by geologic activity.DRock layers that are the thickest are the oldest because they represent a longer span of time in which the rock layer was formed

Cuvier thought that lower layers of rock were older than those above them. This principle describesMultiple choice question.natural selection.polymorphism.uniformitarianism.superposition.

A geologist recorded fossil data for three different organisms found in a rock layer: ​​Fossil X: existed 510 to 250 million years ago, is found in very few locations, and has unique fossil features.Fossil Y: existed 100 to 65 million years ago, is found in many different locations, and has unique fossil features.Fossil Z: existed 400 million years ago to present day, is found in many different locations, and has similar features to other fossils.Part AWhich statement best explains which fossil the geologist should use to compare the rock layer to other layers and estimate when the layers were deposited?

The principle of fossil succession states thatGroup of answer choicesevery rock layer contains only one species of fossil.every fossil species spans only a limited range of rock layers, corresponding to the time period over which it lived.fossil species found in rock are the same as species living today.the same fossil assemblages appear throughout geologic time in a repeating intervals.
