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.

From the internet, given options:
The solar wind produces the northern and southern lights.
The solar wind can cause the formation of new elements.
The solar wind causes temperature changes on Earth's surface.
The solar wind disrupts communication systems.
The solar wind distorts Earth's magnetic field.
Answer:
The solar wind produces the northern and southern lights.
The solar wind disrupts communication systems.
The solar wind distorts Earth's magnetic field.
Solar winds are very energetic particles moving at a velocity of about 905km/s from the sun. They are made up of extremely hot particles from the outer atmosphere the sun called the corona. These particles consists of electrons, protons, plasma flowing outward into the solar space from the sun.
Due to their nature, they are know to produce the northern and southern light known as aurora when they come in contact with the earth atmosphere.
Solar winds disrupts radiowaves which are known as the facilitators of communication systems.
They also disrupt the magnetic field of the earth. These jets streams can interact with the earth magnetic field.
Answer:
With the strong political control, the British were able to monopolise the trade with India. They defeated their foreign rivals in trade so that there could be no competition. ... Heavy duties were imposed on Indian goods entering Britain so as to protect their own industry.

Explanation:
The Enlightenment beliefs that influenced the American Revolution were natural rights, the social contract, and the right to overthrow the government if the social contract was violated. ... As stated before, without the Enlightenment there would not have been a revolution, resulting in no American Government.
