A teacher gave students this diagram of rock layers. The teacher directed the students to determine the relative age of each rock layer based only on the information presented in the diagram.
Which method can BEST be used by the students to determine the relative age of these layers?
radiometric dating
rock type evaluation
the law of superposition
principle of uniformitarianism
The radioactive isotope content of a rock can be used to identify which property of the rock?
the total mass of the rock
the rate at which the rock formed
the types of fossils that the rock contains
the amount of time passed since the rock formed
The graph shows possible changes to sea level over geologic time.
What did scientists MOST likely study to construct this graph?
molten magma
extrusive igneous rocks
sedimentary layers
foliated metamorphic rocks
Which statement best describes the Law of Superposition?
Each sedimentary layer of rock represents 1,000 years of Earth’s age, much like the rings of a tree.
In undisturbed layers of sedimentary rock, the upper rock layers are older than the lower rock layers.
In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.
Rocks that form near volcanoes are older than surrounding rock.
A scientist finds the bones of a dinosaur. What could help the scientist determine the approximate age of the dinosaur bones?
the birds living in the area of the bones
the weather conditions in the area of the bones
the kinds of trees living in the area of the bones
the index fossils in the area of the bones
The diagram below shows two sections of rock layers found several miles apart.
Based upon the information in the diagram, which conclusion can best be made?
The rock layers contained fossils identical to each other.
Rock layers are laid down from the youngest to the oldest.
Rock layers containing similar fossils were formed at the same time.
Several different fossils were found in rock layers in a geologic column. Above these rock layers, the fossils were almost nonexistent. Which most likely explains these observations?
A nonconformity occurred.
All the organisms migrated.
A period of mass extinction occurred.
This diagram shows fossils from different eras of geologic time.
Which index fossil would indicate the oldest rock?
Venericardia planicosta
Nerinea trinodosa
Paradoxides pinus
The diagram shows a cross-section of several rock layers and geological features.
Based on the diagram, which is true?
Layer U is the oldest.
Layer Z is the youngest.
Layer T is older than layer S.
Layer X is older than layer Y.
Fossils were discovered in four different sedimentary rock layers as shown below.
Which best describes the age of the fish relative to the age of the fern and the age of the shell?
The fish is older than both the fern and the shell.
The fish is younger than both the fern and the shell.
The fish is older than the fern, but younger than the shell.
The fish is younger than the fern, but older than the shell.
