C. 6.81x10^-4
It is negative 4 because the 6 is 4 digits away from the first 0.
Scientific notation has one number and then the decimal place so it can not be A or E.
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.
