What process occurs when an organism's remains are buried quickly by sediment after death? | Card: 1 / 30 |
This process is known as fossilization, where rapid burial prevents decay and scavenging, allowing for the preservation of remains. | Card: 2 / 30 |
Fossils found in sedimentary rock primarily consist of ___ and ___ that provide insight into ancient life. | Card: 3 / 30 |
Index fossils help date rock layers.
| Card: 6 / 30 |
True or False: Trace fossils include actual remains of organisms, such as bones or teeth. | Card: 7 / 30 |
False. Trace fossils are evidence of an organism's activities, such as footprints or burrows, not the actual remains. | Card: 8 / 30 |
Which type of fossil forms when minerals fill in the hollow impression left by an organism? | Card: 9 / 30 |
Cast fossils form when minerals fill in a mold, creating a replica of the original organism. | Card: 10 / 30 |
I am a fossil that shows features of both fish and early land animals. What am I? | Card: 13 / 30 |
Tiktaalik, a transitional fossil representing a link between fish and amphibians. | Card: 14 / 30 |
Fill in the blank: The principle of superposition states that in undisturbed layers of sedimentary rock, the ___ layers are at the bottom and the ___ layers are at the top. | Card: 15 / 30 |

Radiometric dating measures the decay of radioactive isotopes to determine the absolute age of rocks and fossils. | Card: 18 / 30 |
Riddle: I can tell you about ancient seas or dry deserts, and I come from the past, yet I am frozen in time. What am I? | Card: 19 / 30 |
What happens to the remains of a fish after it sinks to the bottom of a lake and is covered by sediment? | Card: 21 / 30 |
The soft tissues decay, while the bones become protected and can eventually be replaced by minerals, leading to petrified fossils. | Card: 22 / 30 |
Fossil record shows evolutionary changes.
| Card: 26 / 30 |
Fill in the blank: A fossilized dinosaur footprint is an example of a ___ fossil. | Card: 27 / 30 |
Mass extinctions significantly alter biodiversity and can lead to the rise of new species, marking boundaries between geological periods. | Card: 30 / 30 |
