Answer:
When the magma, a molten rock flows as lava at the planet's surface, the surface gets cooled after a long, this whole process cause formation of some kinds of minerals on that surface.
Explanation:
Magma and Lava both are types of molten rock. The underground molten rock is called magma while the exploded molten rock on surface is known as lava. When these rocks cools down they get solidified and form crystal rock structure. Cooled magma is called plutonic igneous rock and cooled lava is called volcanic igneous rock. These rock crystals are of different sizes and consist several minerals such as Silicon(Si), Sodium (Na), Potassium (K), Aluminium (Al), Iron(Fe), Magnesium(Mg), Calcium(Ca). Some rocks that forms minerals consist high amount of iron. The amount of minerals and elements in every rock can very depending on shape and size.

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.
