Answer:
it helps researchers sense things on earth. they are usually on aircraft or in a satellite.
Explanation:
it collects data from a different level detecting the energy from the earth. this energy comes naturally from the earth's surface. it even most commonly picks up reflected sun light (which is also a source of radiation)
In geology, the Radioactive dating is significant because its provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.
<h3>What is a Radioactive dating?</h3>
This refers to the technique that is used to know the date of materials such as rocks or carbon in which the trace radioactive impurities were selectively incorporated when they were formed.
It determines the dating of rocks and minerals through the use of a radioactive isotopes, it is also useful for igneous and metamorphic rocks that cannot be dated by the stratigraphic correlation method.
As the carbon dating helps to determine the age of an object containing organic material by using the properties of its radiocarbon, it is considered a poor tool for finding the age of the dinosaur skull in the purple layer because the collagen in the dinosaur's bone has usually long since decayed away and is therefore unavailable for radiocarbon dating.
