Relative Dating

Relative dating and rock cycle study questions

QuestionAnswer
A rock cliff of parallel rock layers is slanted at an angle. What is this most likely evidence of? faults
If a fault cuts through multiple layers of rock, which is most likely true? An earthquake happened after the layers formed.
Which evidence would best indicate that four-legged land animals might have a fish ancestor? fossils of sin with bones on their fins arranged like bones of land animals.
Which best describes the distribution of sediment particles by size in a sedimentary rock layer? larger sediment particles will be located at the bottom of a sedimentary rock layer and smaller particles will be located at the top of a sedimentary rock layer.
What can be concluded about the age of fossils in undisturbed rock layers? The bottom layer has the oldest fossils.
An irregularly shaped rock formation is found within a group of parallel rock layers. What most likely created this formation? lava intrusion
Scientists studying rock layers classify the top layer as the most recent, followed by older layers that are uncovered as they did deeper. Which law explains this method of relative dating? law of superposition
Around which landforms can scientists most likely find igneous rocks? volcanoes
Sedimentary rock layers are typically deposited horizontally. Which best describes how a fault will affect the appearance of horizontal sedimentary rock layers? Sedimentary rock layers will appear broken and shifted due to a fault
How are igneous rocks formed? by cooling and hardening of molten rocks from inside the Earth
What role do faults play in the Law of Cross Cutting Relationships? Faults are younger than the layers they cut through
A sample of soil contains many igneous rocks. Which feature was most likely nearby? volcano
In 1785, James Hutton, stated that evidence of past occurrences can be used to explain events which happen today. Which could most likely bus used to explain an event in the geologic past? earthquakes
What is the best possible explanation for how abrupt changes in rock layers could happen? impact of a large asteroid
Red layers of rock formed 2 billion years ago. Layers before that were not red. Red layers formed when photosynthetic organisms first evolved. Which best summarizes this phenomenon? biosphere changed the lithosphere
In a rock cliff, the rock layers run straight across and then jump up a foot and then run straight across again. What could have most likely caused this? fault
How are sedimentary rocks formed? by hardening and cementing of layers of sediment
What is the relative age of an igneous rock intrusion between domed layers of sedimentary rock? It is younger than the sedimentary rock
A fault is found that cuts through lower rock layers but not this above it. What can most likely be concluded? the fault is younger than the layers it cuts through, but older than the layers above it.
Where would evidence of earthquakes most often be found throughout Earth's history? along fault lines
What can be shown by the folding, breaking, and uplifting of some rock layers? The youngest layers are not always on top.
Why are fossils commonly found in sedimentary rocks but not in igneous rocks? Igneous rocks are formed from molten rock, while sedimentary rocks are formed from compacted sediments.
Fossil remains of a trilobite are most likely to be found in which type of rock? sedimentary
Which best explains how thrust faults appear to violate the law of superposition? older layers of rock are moved onto younger layers of rock.
Despite that iridium is much less abundant on Earth than gold, clay located t the K_T boundary contains at least twice as much iridium as gold. How does this statement support the asteroid theory? by providing evidence that the iridium came from a source outside the Earth system
According to Dr. Shubin in his book, Your Inner Fish, what were the first hard "hydroxyapatite-containing parts found in the fossil record? teeth
In comparing foraminifera above the K-T boundary with those found below this boundary, which statement is true? forams above the boundary are smaller and less diverse than those below.
Fossilized dinosaur eggs have been found in the third of five rock layers. Based on the law of superposition, which best represents the age of the eggs? they are about the same age as the third rock layer
