Early Earth Review

How do the methods used to date fossils help in understanding the timeline of life on Earth?

• They allow for the precise measurement of the Earth's age

• They help correlate layers of rock with periods of time and evolutionary events

• They provide exact dates for all events in Earth's history

• They are only used for dating human artifacts

What is the significance of the geological time scale in understanding Earth's history?

• It measures the speed of molecular changes.

• It provides a timeline of Earth's history and major events.

• It predicts future extinction events.

• It records the current biodiversity on Earth.

What is relative dating, and how is it used in geology?

• It determines the exact age of a fossil.

• It compares the age of one fossil to another.

• It measures the rate of extinction.

• It calculates the molecular changes over time.

• Extinction

• Speciation

• Evolution

What is the main difference between absolute dating and relative dating?

• Absolute dating provides a specific age, while relative dating places events in sequence.

• Absolute dating is less accurate than relative dating.

• Relative dating uses radioactive isotopes, while absolute dating does not.

• Relative dating is used for rocks, while absolute dating is used for fossils.

Plate Tectonics

• Theory that states the continents are stationary.

• Theory that states older rocks are found above younger rocks.

• Theory that states that the rigid crust sections move along the mantle.

• Theory that states the moon formed about the same time as Earth.
