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.
Hello!! I always remember recessive genes as someone having a passive personality and dominant genes as having an assertive personality. Therefore, dominant genes would mask others when present because they have that assertive personality. If you think about it as babies, when their dad has darker hair and the mother has lighter hair, the baby will most likely have darker hair because the darker hair is the dominant gene.
