Which of the following BEST describes the fossil at Point 3 when compared with the fossils at Points 1 and 2?

The fossil at Point 3 is older.

The fossil at Point 3 is less common.

The fossil at Point 3 is smaller.

The fossil at Point 3 is more complex.

A section of a rock layer is shown. The evidence in these rock layers BEST support which conclusion?

The oldest fossils in this section of rock are trilobites.

Eurypterids are related to modern-day scorpions and crabs.

Eurypterids were the least common type of organism in this section of rock.

There is some overlap in the presence of brachiopods and ammonites on Earth.

Geologists use radiometric dating, the law of superposition, and index fossils to establish the ages of various rock layers in a formation. Why would a geologist use the law of superposition and index fossils to date a rock formation when radiometric dating is available?

Radiometric dating is inaccurate when used on sedimentary rocks.

Calculating ages using index fossils confirms evolutionary sequences.

Radiometric and fossil dating are only effective on organic matter.

The law of superposition gives the most specific dating information.

Which of these provides the BEST evidence that the distribution of Earth’s oceans has changed over time?

marine fossils found on land masses

seismic activity along plate boundaries

sediment buildup on continental slope

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

the same environment at about the same time.

the same environment at different times.

different environments at about the same time.

different environments at different times.

Scientists estimate that if index fossils were deposited during a certain time frame, then the entire rock layer was also deposited at the same time. A scientist finds Trophite fossils. According to the chart above, in what era and period was this rock layer deposited?

Paleozoic era; Mississippian period

The Key Largo limestone makes up the islands of the Florida Keys. This rock layer formed between 2 million years ago and 10,000 years ago. It is composed of fossil coral, marine plant fossils, and fossil invertebrate shells. Which statement correctly explains why this rock layer is now above sea level?

Earth’s climate was warmer at times during the past 2 million years.

Earth’s climate was colder at times during the past 2 million years.

It has been pushed above sea level by volcanic activity during the past 2000 years.

It has been pushed above sea level by tectonic plate activity during the past 2000 years.

A complete fossil has been found of a type of bird that cannot be identified. What can MOST likely be determined about the bird from the fossil?

The bird existed at one time but is now extinct.

The bird lived for a very short time.

The bird lived in a dry environment.

The bird was not well preserved during the process of fossilization.

Paleontologists are scientists who study evidence of past life on Earth. Which method do paleontologists MOST likely use to determine the forms of life that existed millions of years ago?

examine current species of plants and animals

research past species in the library

Rich beds of marine fossils have been found in Florida. By dating these fossils, scientists can BEST determine

the period during which Florida was covered in water.

when Florida collided with the North American continent.

the date when organisms moved onto dry land.

when the atmosphere of Earth was more humid than it is today.

For many years scientists thought that dinosaurs rapidly replaced their ancestors. New information shows that dinosaurs and their non-dinosaur ancestors may have existed together for tens of millions of years. Which evidence MOST likely made it possible to support the idea that dinosaurs and their ancestors coexisted for millions of years?

Bones of three different species were found in the same rock layer.

Fewer fossils were found of amphibians than of dinosaurs.

More fossils found were of larger organisms than of dinosaurs.

Herbivore bones were found in each rock layer.

Which of these conditions would MOST likely be shown in the fossil record as a reason for mass extinctions?

falling sea levels and global cooling

increased competition for resources

organisms with beneficial traits

Trilobites are extinct animals that lived in the oceans. Fossils of these animals can be found in dry areas such as Cincinnati. What does this indicate?

Cincinnati was once covered by the ocean where trilobites lived.

Trilobites now live underground.

Trilobites are the ancestors of jellyfish.

The environment changed, creating small saltwater lakes in Cincinnati.

Structural geologists study rock formations to determine the type of environment in which the rocks formed and the events that shaped the rocks. Paleontologists study fossils found in rock formations. Scientists in both these fields have a common interest in discovering the

history and processes of Earth.

elements that make up the crust.

types of minerals that make up sediments.

relationships between Earth and other planets.
