What would you use to do absolute dating of a rock layer?
There are several ways to do absolute dating of a rock layer. One of these is to use the radioactive decay of the isotopes that are naturally found in rocks.
What is shell element example?
it is like another layer. a different unit. an outer layer of the nucleus.
How many electrons are supposed to be on the outter layer?
Depends on what element you are talking about.
What did hershey and chase discover after the p-labeled phages infected the bacteria most of the radioactive phosphorous found in the layer containing?
it was phage
What is called when organisms are trapped in sedimentary rock?
when an organism is trapped in sedimentary rock, it will die and the organism will slowly decay, but it won't decay altogether and you get a fossil. the older the fossil is the lower down it will be in a sedimentary layer. that's called superposition...

What is layer of bacteria on your teeth called that leads to decay?
what is a layer a bacteria on your teeth it can lead to decay what is it is it plack
Radioactive decay is the most dangerous?
There are three types: Beta decay, alpha decay, and gamma decay/gamma rays. They are all dangerous if exposed to a high amount of radioactive matter. When the radioactive isotope undergoes beta, alpha, and gamma decay, there is an emission of a beta particle, alpha particle, and gamma ray (respectively). In highly radioactive matter, there are often trillions of radioactive isotopes that emit these particles and/or rays - and they are very high-energy once emitted. However, they are only dangerous when exposed to a high amount.
Why is it hot at the core of the Earth?
The Earth's core is made of extremely hot metal under intense pressure, surrounded by a layer of extremely hot molten metal. Because of the force of gravity, many of the heavy radioactive metals have concentrated here, and the heat is caused by the radioactive decay.
What is the true age of a rock or fossil?
The method used will be determined by the rock type, but the age of a rock will be determined by a determination of the amount of decay of a radioactive isotope, either contained in the rock, or in a geologic layer of rock coinciding with a fossil.
What are all the sources of planetary heat that resulted in layer differention and molten cores?
The heat from when the planet formed and accreted, which has not yet been lost, frictional heating, caused by denser core material sinking to the center of the planet and heat from the decay of radioactive elements.
What element is a danger to the ozone layer in the stratosphere?
Ozone element is in danger. It is present as ozone layer.
How is the ozone layer related to chemistry?
The production and decay of ozone are chemical processes.
What test do geologists use to discover the age of a fossil?
Geologists often use relative dating. When a fossil is found in a rock layer that has been dated, they know the age. If the fossil is found between two dated rock layers, they have an approximate age. If it's found above a dated layer, than it's younger, and vice versa. To date a layer of rock, radiometric dating is used. This measures the trace amount of a radioactive isotope, such as a uranium isotope or potassium isotope, which is then compared to its decay product, lead or argon, respectively, for these examples. More decay product and less of the original isotope means the layer is older, and vice versa. Index fossils can also be used. These are common fossils with a wide distribution that only existed for a short time. Then, when these are found in a rock layer, it is known that the rock layer formed when that organism existed.
How could you determine the exact age of landfill layers?
You could determine the age of a landfill layer by carbon dating food that was found in the layer. Or checking the date on the newspapers in that layer.
What type of radioactive decay has the largest and most damaging particles?
The largest radioactive emission is the alpha particle, which consists of two protons and two neutrons, and is, in effect, a helium ion. The term radioactive particle is used for a small radioactive mass made up of radionuclides. This is different from a radioactive emission, and is not specific as to size.
What is the data element for the Transport layer?
