Answer:
potassium-argon dating
Explanation:
Potassium-argon (K-Ar) dating technique is the most appropriate dating method for establishing the age of a volcanic ash. It is most applicable for dating minerals and rocks more than 100,000 years old. It is based on measuring the product of the radioactive decay of an isotope of potassium (k) into argon (Ar). Since potassium is a common element found in many volcanic ash layer, the time since re-crystallization is calculated by measuring the ratio of the amount of argon 40 (Ar-40) accumulated to the amount of potassium 40 (K-40) remaining in these volcanic ashes.
The information that is the most essential in order to determine the size of the orbital would be the quantum number n or the principal quantum number. It is an indirect method or measure in describing the electron orbital's size. It has value of an integer and it can never have a value of zero.
Answer:
Density, Temperature, and Pressure all increase. The pressure at the boundary between the mantle and the outer core of Earth is inferred to be approximately... 1.4 million atmospheres. What is the inferred temperature at the boundary between Earth's stiffer mantle and outer core?
