How did the lab activities you answer the lesson
question: how are relative and absolute dating methods
used to determine the age of rocks and fossils? what did
you learn from conducting this lab?

A known aged rock or fossil is used in the relative dating while radio isotopes are used in absolute dating method.

Relative dating method:

It compares the rock or fossil with similar rocks which age is already known to determine the approximate age for the fossil or rock.  

Absolute dating method:

It use the radio element dating to determine a precise age of rocks and fossils .

Therefore, a known aged rock or fossil is used in the relative dating while radio isotopes are used in absolute dating method.

The relative method for dating the age of rocks and fossils helps to date the rocks and fossils by determining the approximate age for the fossil or rock by comparing it to something whose age is already known like similar rocks and fossils. In fact, there are certain rocks and fossils which serve as index fossils for comparison.

Absolute dating method tends to determine a precise age of rocks and fossils by radiometric dating of the isotopes of the rocks and fossils.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

condensation. good luck!
