stone tools

Question 1

how are stones tools dated using carbon dating

Answer 1

by looking at the natural radioactive decay or an isotope of carbon we can estimate how long ago an organism lived
finding a once living material in the rock

Question 2

how can stone tools be dated using stratifying rock layers

Answer 2

each layer of sediment and everything in it was formed at the same time
so we can date once living fossils in this layer to estimate when the tool was formed
