Fossil Evidence of Evolution

What are epochs?

• Epochs are larger time units within the geological time scale, which are longer than periods.

• Epochs are smaller time units within the geological time scale, which are shorter than periods.

• Epochs are the same as periods in the geological time scale.

• Epochs are units of time used in astronomy to measure the age of stars.

What is carbonization?

• Carbonization is a process where organic material is reduced to carbon, forming a fossil.

• Carbonization is the process of converting carbon dioxide into oxygen.

• Carbonization refers to the method of extracting carbon from coal.

• Carbonization is the process of burning carbon-based materials to produce energy.

What is absolute-age dating?

• A method to determine the actual age of a rock or fossil using radiometric dating.

• A technique to estimate the age of a rock based on its position in layers of sediment.

• A process of dating fossils based on the types of organisms found in the same layer.

• A way to measure the temperature of rocks to determine their age.

What is the geologic time scale?

• A chart that divides Earth's history into different time units.

• A timeline of human history.

• A map showing the locations of geological formations.

• A scale used to measure the age of rocks.

What is a period in geological time?

• A subdivision of an era in the geological time scale, representing a specific span of time.

• A unit of measurement for the age of rocks.

• A type of fossil found in sedimentary layers.

• A time frame used for historical events.

What are eons?

• Eons are the shortest time units in the geological time scale.

• Eons are the longest time units in the geological time scale.

• Eons are periods of time used to measure human history.

• Eons are units of time used in astronomy.

What is a mold in fossil terms?

• A fossilized impression of an organism in a rock.

• A type of rock formed from volcanic activity.

• A preserved piece of amber containing ancient insects.

• A layer of sediment that has not yet fossilized.

How do fossils form?

• Through volcanic activity and lava flow

• By sedimentation, mineralization, and preservation of organic material

• Only through freezing and thawing processes

• By the immediate burial of organisms in tar pits

What is relative-age dating?

• A method to determine the exact age of rocks and fossils.

• A technique used to compare the ages of rocks and fossils in relation to one another.

• A process for dating organic materials using carbon isotopes.

• A way to measure the temperature of rocks during formation.

What is the significance of fossils in understanding evolution?

• Fossils provide evidence of past life forms and their changes over time, helping scientists understand the process of evolution.

• Fossils are primarily used to date rocks and determine the age of the Earth.

• Fossils are remnants of ancient civilizations and do not relate to biological evolution.

• Fossils are only important for studying extinct species and have no relevance to current species.
