Answer:
B.) 119.954 years
An intrusion crosses and extrusion. The extrusion is the oldest layer and an intrusion is always younger. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.
Absolute dating is the process of determining an age on a chronological or specified time scale in which events occurred in archaeology and geology.The most common method of absolute dating uses by geologists is radiometric dating methods which is based on the natural radioactive decay of certain elements such as potassium and carbon found in the rocks.
The carbon-14 isotope is used in radiocarbon dating, but is only useful for measuring recently formed rocks in the geologic past. By comparing the ratio of parent isotope with a known half-life to daughter product in the rock, the age of the rock can be determined.
Therefore, An intrusion crosses and extrusion. The extrusion is the oldest layer and an intrusion is always younger. The decay of Potassium-40 isotope known as potassium-argon (K-Ar) method allows dating of materials that up to 1,000 billion years old.
