Question

what are the factors that contribute to magma formation ?​

Answer 1

Answer:

Magma Formation

 Magma can be formed either by melting of Earth’s crust or by melting within the mantle. The four main factors involved in

the formation of magma are temperature, pressure, water content, and mineral content.

 Temperature generally increases with depth in Earth’s crust. This temperature increase is known as the geothermal

gradient.

 Pressure also increases with depth as a result of the weight of overlying rock. The increased pressure on a rock also

increases the rock’s melting point.

 Rocks and minerals often contain small percentages of water, which changes the melting point of the rocks. As water

content increases, the melting point decreases.

 Rocks melt at lower or higher temperatures because their component minerals have lower or higher melting points. In

general, rocks rich in iron and magnesium melt at higher temperatures than rocks that contain higher levels of silicon.
