Radioactive dating how stuff works 121 dating teletext
It’s important that we allow God’s written record of history, the Bible, to guide our thinking about the past—this includes our understanding of the age of the Earth/universe How many times have you heard something like, “This animal lived 50,000 years ago”, or “This person died 20,000 years ago’?Have you ever wondered how the scientists knew the age of the bone?
It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.
Those who don’t accept the Biblical account of history look for other ways to discover the age of things.
One of these methods is based on a substance found in our bodies, plants and all living things—it’s called carbon. This makes the plant appear to have died many more years ago than it actually did (for example, the plant might appear to be, say, 3,000 years old, rather than 2,000).
So if scientists wanted to measure the age of a fossil using this method, they would look for a nearby layer of igneous rock (e.g.
rock that forms from lava from a volcanic eruption)—perhaps in the rock layers above where the fossil was found, or in the layers below.
Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.
