Front

What is Relative Dating?

Back

Relative dating is a method used to determine the age of rocks and fossils in relation to one another, without providing an exact age.

Front

What is Absolute Dating?

Back

Absolute dating is a method used to determine the exact age of a rock or fossil, often through radiometric dating techniques.

What is the Law of Superposition?

Back

The Law of Superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest layers are at the top.

Front

What is a Half-Life?

Back

A half-life is the time required for half of the radioactive atoms in a sample to decay into stable material.

Back

Radiometric dating is a technique used to date materials by comparing the abundance of a radioactive isotope to its decay products.

What does it mean when we say 'I am older than my sister'?

Back

This is an example of relative dating, as it compares ages without providing specific numerical values.

Front

What is the difference between Relative and Absolute Age?

Back

Relative age compares the age of rocks and fossils to one another, while absolute age provides a specific age in years.

Front

What is an example of a Relative Dating method?

Back

An example of a relative dating method is using the position of rock layers to determine their age.

Front

What is an example of an Absolute Dating method?

Back

An example of an absolute dating method is carbon-14 dating, which measures the decay of carbon-14 in organic materials.

Front

What is the significance of Fossils in Relative Dating?

Back

Fossils help establish the relative ages of rock layers by showing which organisms lived at certain times.
