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.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
