The Quaternary sector is the part of the economy that is also sometimes described as the knowledge economy because it includes education activity.
Quaternary sector activity is measures, for example, by the presence and influence of higher education centers, foreign exchange students, research and investigation labs, think tanks, and innovation and entrepreneurship present in an economy.
Advanced technology is also an important aspect of the Quaternary sector that has only grown more important with time.
The oldest rocks will be found at the Mariana Trench.
Explanation:
There is a general rule when it comes to where the oldest rock of a plate is located and where the youngest rock is located. That is based on where there are divergent boundaries and where there are convergent boundaries. The places where there are divergent boundaries are the places where new crust is formed, thus the closest a place is to the boundary the younger the rock is. The places where there are convergent boundaries are the places that are the furthest away from the places where the new rock is formed, so they are where the oldest ones are.
In this case, we have the Pacific plate. The East Pacific Rise is a place where new crust forms, meaning that the youngest crust is there. The oldest crust will be located in the trenches that are the furthest away from it, and that would be the Mariana Trench, which is also the deepest trench in the world.
Other trenches of the Pacific that would be among the candidates for some of the oldest rocks are:
- Kuril Trench
- Japan Trench
- Kermadec-Tonga Trench
