Minerals that grow as crystals in cooling lava can become magnetized if they contain iron.
Igneous rocks are composed of minerals that crystallise at a variety of different temperatures. This explains how a cooling magma could contain some crystals while still being primarily liquid. The Bowen reaction series is the pattern of mineral crystallisation from a magma.
Individual plagioclase crystals can be zoned from more sodium-rich around the exterior to calcium-rich in the centre when cooling occurs reasonably quickly. Because it controls how long the reaction can last before all the silica is consumed, the initial magma's composition is crucial to the crystallisation of magma.

Explanation:
Among the most famous models of location of economic activities is the one that Walter Christaller developed to explain how they are distributed and how they are organized. The theory is called "of the central places" because it assumes that there services are provided people approach to obtain it. In this way a point appears in the space that organizes the territory around itself. Thus, a central place is one that offers services, and to which the population goes to satisfy it.
The services offered by a <u>central point</u> are those demanded by society, regardless of their nature. But not all services have the same price, nor does the population have the same need to travel to obtain them, nor is it willing to go anywhere it is offered. There is a logic of economic behavior that governs the emergence of services and their chances of success.
