The Three Economic Sectors. According to the three-sector theory, all economic activity can be classified into one of three sectors: the primary sector, the secondary sector and thetertiary sector.
The dating technique which was used to establish the age of the volcanic ash at the Laetoli site is: potassium-argon (K/A) dating.
<h3>What is absolute dating?</h3>
Absolute dating can be defined as a radioactive process that is typically used to accurately determine the age of a rock, volcanic ash or fossil, by measuring the decay of the isotopes that is associated with the rock or within the fossils.
Thus, scientists can accurately determine the age of a volcanic ash, rock or fossil by measuring its isotope concentration such as through the use of potassium-argon (K/A) dating.

Answer:
Radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth because the oceanic crust is recycled too frequently at subduction zones,
Explanation:
Radiometric dating of basalt on the ocean floor can not provide us the absolute age of the planet earth due to the subduction. In the process of subduction oceanic plate went below the continental plate as it is less denser. It then melts there and its recycling takes place frequently. So the radiometric dating of basalt on oceanic plate can not provide us the true information regarding the age of the earth.
