History of the Earth Test

Scientists uncover mammoth bones and are able to determine the amount of carbon-14 in the bones. Whichbest explains the use of carbon-14 in studying the mammoth?

• It identifies the species of mammoth
• It identifies the diet of the mammoth
• It determines the age of the mammoth
• It determines the cause of death of the mammoth

Which is the most accurate method used in determining the age of a fossil?

• relative dating
• geologic column
• radioactive dating
• law of superposition

Four sedimentary rock layers are cut by an igneous rock intrusion. Which best describes the relative age of the igneous rock intrusion in comparison to the ages of the four sedimentary rock layers?

• THe igneous rock intrusion is older than sedimentary rock layers W, X, Y and Z.
• The igneous rock intrusion is younger than sedimentary rock layers W, X, Y, and Z
• The igneous rock kintrusion is older than sedimentary rock layer W and younger than sedimentary rock layers X, Y, and Z
• The igneous rock intrusion is younger than sedimentary rock layer W and older than sedimentary rock layers X, Y, and Z.

The diagram shows different layers of sedimentary rock. Each layer is labeled with a letter. Which statement correctly describes the relative ages of rock layers shown in the diagram?

• THe left part of Layber B is younger than the right part
• The left part of Layer F is the same age as Layer M
• Layer R is older than Layer M
• Layer I is older than Layer B

Which characteristic of carbon-14 dating helps scientists determine the approximate time a species became extinct?

• Carbon-14 is not present in more recent fossils
• Carbon-14 increases at a constant rate over time
• Carbon-14 decreases at a constant rate over time
• Carbon-14 can only be found in fossils of a certain period

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 rocks, 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.

Many fossils of large amphibians were found in an area that is currently barren desert. Which is most likely true?

• The climate of the area was once much wetter than it is now.
• Amphibians were once better at surviving in dry environments.
• The amphibians migrated there after a catastrophic event destroyed their habitats.
• The amphibians are not native to the area and their bones were brought there by other animals.

Which method can be used to determine the RELATIVE age of rock layers?

• radiometric dating

• rock type evaluation

• the law of superposition

• principle of uniformitarianism

What role do faults play in the Law of Crosscutting relationships?

• Faults create new types of rock.

• Faults are younger than the layers they cut through.

• Faults are the same age as the layers they cut through.

• Faults have nothing to do with this
