A fossil is ?
The preserved remains, impressions, or traces of once living organisms.
The left over tools of people that lived in the past.
The Layers in sedimentary rock.
How are fossils formed?
Through the process of sedimentation and mineralization
By the rapid cooling of lava
Through photosynthesis
By the evaporation of water
What is the role of sediments in fossil formation?
Sediments protect remains from destruction or decay and help in fossilization.
Sediments dissolve the remains, preventing fossilization.
Sediments have no role in fossil formation.
Sediments speed up the decay process.
What happens to the bones of animals in sediment layers?
They dissolve completely.
Minerals slowly replace the calcium in bones
They are unchanged.
They turn into diamonds.
How do fossils come closer to earth’s surface? Check all that apply.
Through erosion and weathering of overlying rocks
By volcanic activity pushing them upwards
Due to tectonic plate movements
By human excavation activities
How does erosion help to expose fossils?
By wearing away the surrounding rock and soil
By covering fossils with more sediment
By creating new fossils
By preserving fossils in their original state
How are petrified fossils formed?
Through the process of mineralization where organic material is replaced with minerals.
By being frozen in ice for thousands of years.
Through the compression of organic material into coal.
By being trapped in amber.
What does a Paleontologist study? What are some of his tools?
A Paleontologist studies fossils. Tools include brushes, chisels, rock hammers, and magnifying glasses.
A Paleontologist studies the stars. Tools include telescopes, star charts, computers, and cameras.
A Paleontologist studies plants. Tools include microscopes, test tubes, soil samplers, and pH meters.
A Paleontologist studies weather. Tools include barometers, anemometers, thermometers, and rain gauges.
Define a fossil mold?
A fossil mold is a hollow impression left in sedimentary rock by a decayed organism.
A fossil mold is a type of fossil that contains the actual remains of an organism.
A fossil mold is a bug that has been trapped in the sap of a tree.
A fossil mold is a type of fossil that forms when minerals replace the original material of an organism.
What is a fossil cast?
A fossil cast is a replica of a fossil made by filling a hollow mold with sediment or minerals.
A fossil cast is the original fossil bones found in sedimentary rock.
A fossil cast contains preserved bodies of animals that lived long ago.
A fossil cast is a bug that has been trapped in the sap of a tree.
What do you call a very thin coating of carbon on rock?
Carbon film
Graphite layer
Charcoal coating
Soot deposit
What happens to a wooly mammoth if it falls into a boiling tar pit?
The tar preserves the mammoth by preventing decay.
The mammoth is eaten by predators.
The mammoth decomposes quickly.
The mammoth turns to rock immediately.
If a wooly mammoth gets trapped in ice and dies, its body is frozen in the ice, which preserves the organism, even the hair. What is this preservation process called?
Mummification
Fossilization
Cryopreservation
Decomposition
Define a body fossil.
A fossil that consists of the preserved remains of the actual body parts of an organism, such as bones, teeth, or shells.
A fossil that consists of the preserved traces or imprints of an organism's activity, such as footprints or burrows.
A fossil that is formed from the mineralization of organic material over time.
A fossil that is found only in sedimentary rock layers.
Most fossils are found in:
Sedimentary rocks
Igneous rocks
Metamorphic rocks
Volcanic ash
What process measures the decay of isotopes to determine the age of a fossil?
Radiocarbon dating
Thermoluminescence dating
Dendrochronology
Potassium-argon dating
Which of the following could form a fossil? (multiple correct answers)
Which process forms fossils?
variation
adaptation
mineralization
Which of the following is a trace fossil?
Dinosaur footprint
Amber with an insect
Petrified wood
Frozen mammoth
What is amber, and how does it relate to fossils?
Amber is fossilized tree resin that can preserve small organisms.
Amber is a type of sedimentary rock where fossils are found.
Amber is a mineral that replaces organic material in fossils.
Amber is a volcanic rock that contains fossils.
The Law of Superposition states: _________________
That the layers are arranged randomly without any specific order.
In sedimentary rock layers, the oldest layers are at the bottom and the youngest are at the top.
Trace fossils are ___________ evidence of organisms activities.
Body fossils provide ___________ evidence of the organism's physical characteristics.
Most fossils form in ___________ rock
Volcanic
Metamorphic
Sedimentary
