Two general processes used to figure out the age of rocks is relative dating and radiometric dating. We will compare and contrast the strengths and weaknesses of both methods. According to Lutgens and Tarbuck‚ Relative dating is the process in putting events in their proper sequence. Relative dating is based on assumption‚ not able to give an accurate date but an estimated time period where the rock originated from. A Danish scientist‚ Nicolaus Steno is accredited for the Law of Superposition.

Absolute dating methods are used to determine the age of materials. We need to understand how fossils are made so we can date them properly. There are five ways bones are fossilized. They are by permineralization‚ unaltered preservation‚ carbonization‚ authigenic preservation‚ and recrystalization (Shepherd). When a fossil is found you need to make sure that it can be preserved properly so it can stay in the same shape to enable research. Many steps are taken to prepare fossils and conserve them

Where exactly is Oklahoma? When geographers speak of location‚ they are using two separate definitions‚ each with its own useful purpose. The first of these is Absolute Location. Absolute location refers to an exact‚ pinpointed location. Absolute locations involve some sort of measurement‚ whether it’s latitude and longitude‚ an address‚ the number of miles from an exact point‚ etc. Pinpointing Oklahoma on a map using absolute location involves locating latitude and longitude lines on the map.

| Uniformitarianism vs. Catastrophism | Lara Anderson | | Dr. Travis Bradshaw | PHSC 201-A19 | For much of history‚ humans have grappled with the question: Where do we come from? Today there are two main houses of argument which have many different names. They are called secular and religious‚ evolutionists and creationists‚ humanists and theists. However‚ each house subscribes to its own idea of how the world has come about and progressed through history. The secular/evolutionist/humanist

The history of the Earth is categorized into four different geological time eras beginning with‚ the Precambrian Time (4.6 billion-544 million years ago)‚ the Paleozoic Era (544-248 million years ago)‚ the Mesozoic Era (248-65 million years ago)‚ and the Cenozoic Era (65 million years ago to the present). Eras are broken down further into smaller units called periods‚ which help scientists detect changes in Earth’s history. Geologists’s main sources of evidence for geological eras‚ and periods are
