Answer:
At 0 years, an event took place which is known as metamorphosis of igneous rock i.e., formation of igneous rocks from melted magma.
Strontium-90 is a radioactive element which undergoes beta decay to form yttrium-90. It has a half life of approximately 28 years and decay energy of 0.546 MeV. This radioactivity is used by geologist to estimate the age of the rock, fossils, meteorites etc. Other radioactive elements used by the geologists are carbon-40, potassium-40 etc.
Radiometric clock is set when the rock was formed in the past i.e., the moment when an ingenious rock was solidified from molten magma.

<span>Open-mindedness does interfere with scientific progress as it can lead to acceptance of untested ideas. Open-mindedness can lead to actually accepting results that are not true. This is not a great angle for people involved with scientific experiments. Open-mindedness should be limited to the fact that the results can lead to negative answers. People that can accept this theory will ultimately succeed in their strive for creating something new. There is nothing wrong in discarding the results that does not seem to fit the bill.
