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
