Answer:
Partial melting occurs when only a portion of solid is melted. It is thus enriched in the chemical components of minerals with lower melting temperatures and the remaining unmelted portion of the rock is composed of minerals with highest melting temperatures. Partial melting preferentially enriches melts with incompatible elements.
Partially melted rock do not usually experience complete melting inside the Earth, due to their different chemical composition and their melting points.
It is thought that partial-melting processes play a major role in generating more-defined liquids from less-evolved ones, so that many basalts may be the result of partial melting in the upper mantle, and many granites may have derived partly or completely from the partial melting of continental crust (anatexis).With increasing temperature and pressure, the subducted oceanic crust (of basic composition) first undergoes metamorphism and then begins to melt or release watery fluids; this material rises into the overlying mantle, which may also begin to melt, giving rise to intermediate magma.

Answer:
The activities of multinational corporations.
Explanation:
Multinational companies are those economic corporations that offer goods or services in more than one country, thus grabbing large market shares at the international level.
These companies generally have large sums of capital to invest, with which they tend to exert an enormous influence on nations with fewer economic resources. Thus, when investing in underdeveloped countries, these countries give up more than a market share, but also on many occasions their own power to exercise their sovereignty, mainly in relation to their natural resources and the administration of their territory.
