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.
Answer:
strong, long duration winds in a large fetch weak
Explanation:
A fetch is an area of the ocean or sea where wind blows in a fixed direction, this consistent wind leads to waves.
Fetch length is the distance reached by the wave generating winds when measured in from a horizontal direction. The wind creates wave by forming a drag and a frictional drag, the wind the flow over the wave making it grow. Therefore, a strong, long duration winds in a moderate fetch or weak fetch will produce largest waves.
