Geographic location refers to a position on the Earth. Your absolute geographic location is defined by two coordinates, longitude and latitude. These two coordinates can be used to give specific locations independent of an outside reference point.
The correct answer is - intraplate volcanism.
The Hawaiian Islands are volcanic islands, thus islands that have been created by volcanic activity. Unlike most of the volcanic islands, or most of the volcanoes, they are not related to any type of volcanism asociated with plate boundary. These islands are in fact associated with intraplate volcanism.
The intraplate volcanism, unlike the other volcanisms, appears inside the plate, not on the boundary of it. The other, more common name, used for this volcanism is hot spot volcanism. This type of volcanic activity appears on places where there's a hot spot, so even though the plate is on top of it, it manages to penetrate through it, and create volcanoes on the surface.
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.
