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 answer is B I think...
Moose and Lynx might live near the Arctic ocean
The correct answer is (c.) Lithosphere. The lithosphere is not a layer of the atmosphere, instead, it is a layer of the grounds of the Earth. It is the rigid outer layer that consists of the upper mantle and crust.
