Learn how scientists determine the ages of rocks and fossils.
We'll explore both relative and numerical dating on our quest to understand the process of geological dating.
Other firms make products whose tangible value is supplemented by services (e.g., a computer manufacturer provides a computer loaded with software and provides a warranty, technical support, and software updates).
It is not necessary for a firm to physically handle a product to add value—e.g., online airline reservation systems add value by (1) compiling information about available flight connections and fares, (2) allowing the customer to buy a ticket, (3) forwarding billing information to the airline, and (4) forwarding reservation information to the customer.
You may already know how to date a fossil with a rock.
You should already understand that the lower rock strata are generally older than the strata found higher up in the rock.Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur fossils.Recently, he appeared on the evening news to talk about a new dinosaur he just discovered. Paul says he can tell from the fossils that superus awesomus lived on Earth about 175 million years ago.Paul is super awesome, so I'm going to take him at his word.Value can be created in a number of different ways.
