Fossil Dating

The use of a fossil found in a rock to indicate the age of this rock is known as:

• Relative Dating

• Correlation

• Radiometric Dating

• Absolute Dating

What is not a quality of an index fossil?

• Distinctive

• Abundant with wide geological distribution

• Limited live existence

• Contains no hard parts

What is the Principle of Fossil Succession (Superposition)?

• New strata are always deposited on top of existing strata

• Layers of sediment initially extend laterally in all directions and will be the same age over a valley

• The geologic feature which cuts another is the younger of the two features

• Any rock fragments that are included in rock must be older than the rock in which they are included

How many years is Carbon Dating restricted?

• 50 thousand years

• 5 million years

• 5730 years

• 10 thousand years

What is the Principle of Lateral Continuity?

• New strata are always deposited on top of existing strata

• Layers of sediment initially extend laterally in all directions and will be the same age over a valley

• The geologic feature which cuts another is the younger of the two features

• Any rock fragments that are included in rock must be older than the rock in which they are included

What is Radiometric Dating?

• Arrangement of geological events and rocks left behind in a sequence

• Materials found on the rock surface that indicate its age

• Observation of strata to comparatively determine their age

• Technique used to numerically determine the approximate age of fossils or rocks

What is the Principle of Cross-Cutting Relationships?

• New strata are always deposited on top of existing strata

• Layers of sediment initially extend laterally in all directions and will be the same age over a valley

• The geologic feature which cuts another is the younger of the two features

• Any rock fragments that are included in rock must be older than the rock in which they are included

What are times on the geological timeline?

• Eon, Era, Period, Epoch

• Era, Generation, Period, Age

• Age, Era, Phase, Eon

• Integer, Epoch, Eon, Period

What is the Principle of Inclusions?

• New strata are always deposited on top of existing strata

• Layers of sediment initially extend laterally in all directions and will be the same age over a valley

• The geologic feature which cuts another is the younger of the two features

• Any rock fragments that are included in rock must be older than the rock in which they are included

How many years is a half life of Carbon-14?

• 4730 years

• 5250 years

• 5730 years

• 5649 years
