Relative age is the age of a rock layer (or the fossils it contains) compared to other layers.It can be determined by looking at the position of rock layers.Absolute age is the numeric age of a layer of rocks or fossils.Absolute age can be determined by using radiometric dating. Look at the diagram below and then answer this question: We can date the layers of volcanic ash using radiometric dating, but how can we determine the absolute age of fossil A?They cannot compare the features of service and hence have an absolute experience, not relative.
Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy.Absolute and relative are concepts that are used in life to know more about people, things, and ideas.For example, if there is only one internet service provider in an area, the customers, not knowing the features and services of other ISP in other areas, remain content with what they are getting.Let us take a closer look at the two concepts, absolute and relative.When you are looking at an absolute perspective, you are not taking into account other similar people or products.The radiometric techniques that give absolute dating estimates are based on radioactive decay of elements such as uranium. Looking at how rock formations are structured, a geologist may be able to say which rock was developed in which layer in a particular order but not be able to determine that actual geologic age of the layers. Relative Poverty is when people are poor when compared to others around them, but may still have enough money to survive.Geologists also have radiometric methods for absolute dating based on radioactive decay of certain elements. It is based on the cultural environment around them, not on a basic amount necessary for all humans to survive. Current scientific evidence shows that the Earth is: c) more than 4 billion years old 2.Look at the diagram below representing layers of rocks and the fossils buried in them. (The bottom layer is circled)b) Explain how you know which layer is the oldest.(Hint: The Law of Superposition might help you.) According to the Law of Superposition newer rock layers form on top of already existing layers.As more and more layers are deposited, the older rock layers end up at the bottom and the newer ones toward the top. What is the difference between relative and absolute age?
