Several zircon crystals from Australia have been dated to have an estimated age of 4.2 billion years. Which statement BEST describes the period of formation of these crystals?
recently formed
Formed shortly after earth formation
Which method would be BEST for scientists to use to determine the absolute age of a Precambrian igneous rock?
Radiometric dating
Relative dating
Law of superposition
Which statement best describes the Law of Superposition?
older on top younger on bottom
younger on top older on bottom
rocks are all the same age
Which best describes how ice cores are important to the study of geologic history?
They show unconformities, which signal changes in deposition.
They hold index fossils, which are used to date the different ice cores
They contain evidence showing changes in the atmospheric composition over time
A fossil discovered in Colorado dates from the early Mesozoic era. A year later a similar fossil is found in Wyoming that also dates from the early Mesozoic era. These two organisms most likely lived in
same environment around the same time
different environment around the same times
same environment different time
Which characteristic of an index fossil makes it most useful in relative dating of rock layers and other fossils?
existence was brief
lived a long time
lived in certain areas
Which of these provides the BEST evidence that the distribution of Earth’s oceans has changed over time?
hot spots on ocean floor
sediment build up on land
marine fossils found on land
A student is visiting a local limestone quarry and finds fossils of seashells. The quarry is located hundreds of miles from the ocean. The fossils BESTindicate that
area was once below sea level
temperature changed
global flooding
What do transitional fossils best support?
Theory of Biological Evolution
Theory of Geological Evolution
Law of Superposition
Which best describes a species of lizards that adapt to survive under new environmental conditions?
The adapted lizards are a different species as the original lizards.
The adapted lizards are the same species as the original lizards.
The adapted lizards have no relation to the original lizards.
Which evidence would best support the extinction of a past species?
the loss of a species’ habitat
the evolution of a new species
the disappearance of a species’ fossils
How are organisms classified as Eukarya different from organisms classified as Archaea and Bacteria?
Unicellular

membrane bound Nuclei
Which best helps scientists explore the relationship between modern organisms and ancestral species to create a system of biological classification?
fossils
volcanic ash
DNA Evidence
Which best explains the gaps in the evolutionary history of Earth’s life forms?
The soft parts of organisms are the only parts preserved as fossils
Many organisms died without leaving behind fossil remains.
Extinct organisms did not form fossils.
Which geological event is most likely to cause greater diversity in animal populations?
landmass splitting
Land mass coming together
landmass getting larger
Which of these characteristics BEST helps scientists classify organisms?
structure
gender
color
Elephants are native to Africa and Asia, but not to India. Which best explains why elephants are not native to India?
India broke away from Africa 100 years ago.
India broke away from Africa 20 million years ago.
There is not enough rain in India for the elephants to survive.
Imprints of the shells of ocean clams are often found in the rocks of the Appalachian Mountains. What do these imprint fossils MOST likely indicate?
These mountains were once under the ocean.
These mountains once had a more rainy climate
Mountain river clams evolved from ocean clams.
