What is the significance of the geologic time scale?

• It categorizes the Earth's rock strata over time

• It focuses on human history

• It measures historical events

• It provides absolute ages of fossils

What does 'uniformitarianism' imply in geology?

• Natural laws have changed over time

• Current processes are the same as those in the past

• Fossils are only found in certain layers

• Rock layers are always disturbed

What does the term 'absolute age' refer to?

• The age determined by sedimentation

• The age based on fossil comparison

• The relative age compared to other layers

• The exact age of rocks or fossils

What is a half-life in the context of radioactive decay?

• The total lifespan of a rock

• The time it takes for half of a sample to decay
