I think because of the reveloutiones was a very weak country
Ps my not sure
Answer:
(b) Decompression melting , flux melting
Explanation:
Decompression melting : The procedure of decompression melting includes the upward development of the earth mantle to a zone of lower pressure. The decrease in overlying weight empowers the stone to melt, prompting magma arrangement. Magma is shaped by the melting of the earth mantle.
Flux melting :I n molten petrology and volcano logy, flux melting happens when water and other unstable segments are added to hot strong shake. In designing and metallurgy, transition is a substance, for example, salt, that creates a low dissolving point blend with a metal oxide.
Similarly, the expansion of water and other unstable mixes to rocks made out of silicate minerals brings down the softening temperature of those stones.
The human settlements hierarchy is as follows:
- An ecumenopolis is a theoretical construction in which the entire area of Earth that is taken by human settlements, or at least, that those are linked so that to create an urban areas so big that they can shape an urban continuum through thousands of kilometers.
- A megalopolis is a group of conurbations, consisting of more than ten million people each.
- A conurbation is a group of large cities and their suburbs, consisting of three to ten million people.
- A metropolis is a large city with it's suburbs, consisting of multiple cities and towns.
- A large city is a city with a large population and many services.
- A city has many services, but not as many as the large city.
- A large town is a town with population of 20,000 to 100,000 people.
- A town has a population of 1,000 to 20,000 people.
- A village is a human settlement or community that is larger than a hamlet but smaller than a town.
- A hamlet has a very small population, very few services, and only few buildings.
- An isolated dwelling has only 1-2 buildings.
