Relative age dating lesson plan who is lenny kravitz currently dating
Discuss that the changes that have occurred on Earth including the terrain, temperature, landforms and organisms make it difficult to predict where dinosaurs may be found.
Ask: How has the GPS technology helped scientists to locate evidence of changing life forms?
Absolute time, also called chronometric time, gives us distinct measurements and points of reference, such as 65 million years ago or 5 pm.
We get these rock dates and ages with radiometric dating techniques that tell us how old rocks are based on their rate of decay.
You can think of this type of time as how we normally view it on a day-to-day basis: specific intervals or moments measured in days, months, years, etc.
For example, 60 million years is a measure of absolute time. These are numerical representations of time, and they give us specific points of reference.
