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.
