Answer:

It is made of liquid metal.

Explanation:

Earth is divided into few layers, and those layers are further divided into subdivisions. The layer in the central part of the planet is the core, and the core is divided into the inner core and outer core. The outer core is wrapped around the inner core.

The outer core is very thick, 2,200 km thick in fact. Unlike the inner core which is solid, the outer core is made up of liquid metal, mostly liquid iron and nickel. The metal is in liquid form because of the very high temperature and pressure. Because it is composed of metal, the outer core conducts electricity with ease. This layer also is in constant movement, or rather the material in it is constant movement, and this is due to the intense convection.

Answer: B. International migration and voluntary migration: Family A from Mumbai has convinced their close friends Family B to emigrate to London as they did in order to help start up their business.

Currently, migration is classified as voluntary or forced migration and internal or international migration.

Voluntary migration consists of voluntary internal or international displacement, permanent or temporary, to seek better economic opportunities.
Forced migration occurs when the displacement is carried out against the will, due to situations of violence, natural disaster or eviction.
Internal migration is what occurs within the same territory, for example from rural to urban areas.
International migration consists of movements from the country of origin to another country.

In this case, Family A convinces Family B to make an international migration (from India to England) voluntarily (To establish a business).
