Geologic Time. From the beginning of this course, we have stated that the Earth is about 4. How do we know this and how do we know the ages of other events in Earth history? Prior to the late 17th century, geologic time was thought to be the same as historical time. The goal of this lecture is come to come to a scientific understanding of geologic time and the age of the Earth.

In order to do so we will have to understand the following:.

However, by itself a fossil has little meaning unless it is placed within some context Numerical ages estimate the date of a geological event and can sometimes.

Geologist Ralph Harvey and historian Mott Greene explain the principles of radiometric dating and its application in determining the age of Earth. As the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate. Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4. Segment from A Science Odyssey: “Origins. View in: QuickTime RealPlayer. Radiometric Dating: Geologists have calculated the age of Earth at 4.

But for humans whose life span rarely reaches more than years, how can we be so sure of that ancient date? It turns out the answers are in Earth’s rocks. Even the Greeks and Romans realized that layers of sediment in rock signified old age. But it wasn’t until the late s — when Scottish geologist James Hutton, who observed sediments building up on the landscape, set out to show that rocks were time clocks — that serious scientific interest in geological age began.

Before then, the Bible had provided the only estimate for the age of the world: about 6, years, with Genesis as the history book. Hutton’s theories were short on evidence at first, but by most scientists concurred that Noah’s ark was more allegory than reality as they documented geological layering. Using fossils as guides, they began to piece together a crude history of Earth, but it was an imperfect history.

After all, the ever-changing Earth rarely left a complete geological record.

Geologists often need relative know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, dating number of years. This is different to relative dating, which only puts geological events in the order. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes.

These break down over time in a process dating call radioactive decay. Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter. Isotopes are ultimate to geologists relative each radioactive element decays at a constant rate, which is dating to that element. These rates of dating are known, so if you can dating the proportion of parent and daughter isotopes in rocks now, you can calculate relative the rocks were formed.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word “absolute” implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history.

Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. In historical geology , the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young radiocarbon dating with 14 C to systems such as uranium—lead dating that allow acquisition of absolute ages for some of the oldest rocks on Earth.

Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes.
