What are the relative ages of the different layers of rock?
What are the relative ages of the different layers of rock?
According to the law of superposition, in horizontal sedimentary rock layers the oldest is at the bottom. Each higher layer is younger than the layer below it. There are two other rules that aid in determining the relative ages of rocks.
What is a relative age of a rock?
The relative age of a rock is its age in comparison with other rocks. If you know the relative ages of two rock layers, you know which is older and which is younger, but you do not know how old the layers are in years.
How does relative position of rocks reveal something about its history and age?
The relative position of the rocks reveals something about its history because most of the rocks were sedimentary and made up of different sediments that were compacted together through time. This sediments formed layers by layers through the passing of time forming bed layers in the rocks.
How is relative age different from actual age?
1. How is relative age different from the actual date of an event? Relative age only tells us the order in which events occurred, from the earliest to the most recent. Knowing the actual date of an event allows us to say exactly how old something is or how long ago it actually took place.
What are the similarities and differences between absolute and relative dating?
The main difference between absolute and relative dating is that the absolute dating is a technique to determine the numerical age of a rock or a fossil whereas the relative dating is a technique that determines the relative age.

Who invented electronic age?
The device that gave birth to an electronic age, rooted in this new physics, became known (at least in the U.S.) as the vacuum tube. Conventionally, two men figure in the story of its creation: the Englishman Ambrose Fleming, and the American Lee de Forest.

What is the difference between electronic age and digital age?
Although they sound similar, there is a difference between the ELECTRONIC AGE and the DIGITAL AGE. The ELECTRONIC AGE has more to do with the emergence of many electronic types of equipment and the popularity of its use. It is a natural result of the INDUSTRIAL AGE that came before it.
When did the electronic age start?
The electronic age is wha we currently live in. It can be defined as the time between 1940 and right now. The ENIAC was the first high-speed, digital computer capable of being reprogrammed to solve a full range of computing problems.
