RELATIVE DATING is a way to estimate the order of geologic events by using rock layers, index fossils or other methods.
Relative dating is used by geologists to arrange geological events in sequential order. Relative dating usually use six principles to determine the relative age of any rock or fossil. The principles are: principle of superposition, principle of original horizontality, principle of lateral continuity, principle of cross cutting, principle of inclusions and principle of fossils succession.

The most used instruments for the determination of free-living physical activity and energy expenditure are; whole-room indirect calorimeter, Accelerometers and pedometers and also the Doubly-Labeled Water. Indirect calorimetry measures gas exchange from which energy expenditure can be estimated, Double labeled water is the most relevant method for measuring free-living energy expenditure in animals and humans, it is based on exponential disappearance from the body of the stable isotopes (H and O) after a bolus dose of water. Accelerometers and pedometers provide an inexpensive overall measure of physical activity, however they are unable to asses the intensity, frequency and duration of activity or to estimate energy expenditure.
