How do scientist use Radioactive Isotopes to find the absolute age of a rock?
Absolute dating is a radioactive isotope the geologist can use to learn the exact age of the rock.
What fossil fuel is formed by the remains of prehistoric organisms in shallow oceans and lakes?
Petroleum.
Are the dates assigned to earth and its prehistoric remains only estimates?
Of course. No one was actually there.
The remains of many prehistoric insects have been found preserved this way?
Fossil in Amber
When radioactive phosphorus decay it emits a positron will the resulting nucleus be another isotope of phosphorus?
No, whenever an atom emits a positron its atomic number is decreases by one unit (because a proton is converted into a neutron and a positron) but atomic mass remains the same so phosphorus is converted into silicon atom with same atomic mass.
What isotope is most commonly used in the radioactive dating of the remains of organic materials?
carbon-14
What isotope is most commonly used in the radioactive dating in the remains of organic materials?
carbon-14
Can the half life of a radioactive isotope decrease as the isotope decays?
No, the half-life of a radioactive isotope does not decrease as the isotope decays. That half-life remains constant. It's the amount of the substance that decreases as the isotope decays.
. If the half-life of an unstable isotope is 10000 years and only 18 of the radioactive parent remains in a sample how old is the sample?
30,000
What is the remains an imprint or a trace of prehistoric organism?

Which isotope is most commonlt used in the radioactive dating of the remains of organic materials?
Carbon 14... i just did that same question on castle learning haha :)
If an isotope undergoes beta emission?
If a radioactive isotope undergoes beta emission, a. The atomic number changes B. the number of neutrons remains constant c. The mass number changes d. The todo isotope loses and electron
What is petrified remains of prehistoric life?
Fossils.

Does oil come from the remains of prehistoric animals?
yep.
Is the remains or imprint of a prehistoric plant or animal?

What does the half life of a radioisotope represent?
It tells what fraction of a radioactive sample remains after a certain length of time.
