Answer:
Radiometric dating is usually defined as a method that helps in calculating the age of rock depending on the presence of radioactive isotopes and its rate of decay. In order to calculate this, the half-life of the isotope element must be known. This method is commonly used by geologists.
The conditions that are needed to fulfill in order to determine the age of a granitic batholith are as follows-
- The rate at which these materials decay must be a constant
- There should be an exact amount of both the parent as well as the daughter elements.
- Since it is a batholith, so it has formed from the crystallization of magma at a certain depth. So, these granitic rocks must have remained within a closed system, right from the time of its formation.
The various methods of radiometric dating that can be used to date this granitic batholith are-
- Uranium-lead dating- It is an efficient method to date the rocks that are of about 4 to 4.5 billion years.
- Potassium-argon dating- It is also commonly used to date rocks that are about 4 billion years old.

Louis XIV believed in the "divine right of kings," where he said that he had the right to rule because he was ordered by God. He uses this as basically an excuse to rule like a tyrant and have autocratic control over everything.
