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 amount of sillca in the magma and temperature are factors that determine the viscosity of magma true or fault

Answer:

The two primary factors that impact how a well of lava will eject are consistency and gas content. 

Explanation:

Both are identified with the arrangement of the magma. Hawaiian volcanoes will in general emit basalt , which is low in consistency and low in gas content (about 0.5 weight percent).

The higher the level of silica substance of magma, the more thick it is. Since a magma with less silica substance is moderately liquid and has a high capacity to stream (low consistency)
