In the geologic history of the Earth, which time is characterized by the dominance of reptiles and the presence of small mammals, birds, and flowering plants?

• Cenozoic

• Mesozoic

• Paleozoic

• Precambrian

Scientists discovered a 150 kilometer-wide crater near the Yucatan peninsula. The crater is believed to have formed from the impact of a giant asteroid 65 million years ago. How did this catastrophe affect Earth's environment at that time?

• It altered the composition of soil in that area

• It caused mass extinction of the life-forms of the time

• It resulted in the start of extensive volcanic activity

• It caused continents to collide with each other.

In a study, scientist concluded that the first chordates appeared on Earth right after the Precambrian Age. What statement supports this?

• Fossils of the earliest chordates back to the first epoch of the geologic time scale.

• Fossils of the earliest chordates date back to the first period of the geologic time scale.

• Fossils of the earliest chordates date back to the second era of the geologic time scale.

• Fossils of the earliest chordates date back to the third period of the geologic time scale.

Which geologic time period was the longest?

• Cenozoic

• Mesozoic

• Paleozoic

• Precambrian

A team of paleontologists discovered a fossil that formed when an organism was buried in sediments that changed into rock. The buried organism decayed and left an impression of its shape, which was filled with sand and mud before hardening into the shape of the buried organism.

What type of fossil did the paleontologists discover?

• Cast Fossil

• Mold Fossil

• Petrified Fossil

• Preserved Fossil

Which sequence shows the correct order of the geologic time periods from youngest to oldest?

• Cenozoic, Mesozoic, Paleozoic, Precambrian

• Precambrian, Paleozoic, Mesozoic, Cenozoic

• Paleozoic, Mesozoic, Precambrian, Cenozoic

• Mesozoic, Cenozoic, Paleozoic, Precambrian

The image shows the unturned layers of sedimentary rocks with embedded fossils.

A student labels the fossils from 1 to 4. What could be true about the fossils?

• Fossil 1 is younger than fossil 2

• Fossil 1 is older than fossil 4

• Fossil 3 is older than fossil 2

• Fossil 3 is younger than fossil 4
