Explain how carbon dating is used to determine the absolute age of fossils - Carbon Dating Flaws – Doesn’t Carbon Dating Disprove the.


In this lesson, students explore how living things are affected by changes in the environment by studying the case of the snowshoe hare and how it’s impacted by climate change.

Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods. We are told that of all the radiometric dates that are measured, only a few percent are anomalous. This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points. Since there doesn't seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.

Thrown together and mixed well, these simple ingredients make a composite , which is the name we give to a hybrid material that's better in some important way than the materials from which it's made. In the case of concrete, the "important" thing is that it's strong, hard, and durable. Thinking of concrete as a composite material, the cement hydrate is the background, binding material (technically called the "matrix") to which the sand and gravel add extra strength (the "reinforcement").
