Answer:
Plate tectonics
Explanation:
Expansive ranges of mountains seen on the earth surface can be best attributed to the concept or theory of plate tectonics.
According to this theory, the earth is broken into series of slabs called lithosphere which moves over the weak and semi solid asthenosphere below.
- The plate interactions beneath leads to the formation of different topographies on the earth surface.
- Most mountain ranges can be ascribed to either plate convergence or divergence.
- During plate convergence, they grind against one another and builds up mountains.
- At a divergent margin, magma wells up and it is cools and solidifies covering an extensive expanse of area.

That is why their democracy is very fragile because those who are tasked to keep law and order are the ones breaking the laws to fill their own pockets and satisfy their own interests to the detriment of the people.
