What causes magma beneath the volcano to rise to the surface?
Increasing pressure pushes the magma upwards. This rising pressure can be caused by many different things.
When Pressure from rising magma can crack underground rock causing what?
When pressure from rising magma cracks underground rock, it can cause seismic activity and result in earthquakes. The cracks in the rock can create pathways for magma to reach the surface, leading to volcanic eruptions. Additionally, the release of pressure can trigger landslides or avalanches in the surrounding area.
What is another name for the mineral crystals in cooling magma or lava?
Rock flows at great pressure and temperature Rock flows like putty in this inhospitable environment of great pressure and temperature. Rock that surrounds rising magma deforms, allowing passage of the magma. This partially molten magma eventually rises to the base of the continental crust. The upper continental crust is more rigid than the mantle, so the magma must force its way upward through cracks or by melting surrounding crustal
Can rising magma become less fluid as it decompresses?
Yes, rising magma can become less fluid as it decompresses. When magma rises towards the surface, the pressure decreases, which can cause dissolved gases to come out of the magma and create gas bubbles. These gas bubbles can increase the viscosity of the magma, making it less fluid.
What happens to the dissolved gases in magma as the magma ascends towards the surface of earth?
As magma rises, the gases contained within expand due to the decrease in pressure on them as they rise. This creates bubbles that float through the magma, Like the sudden decrease in pressure on the gas in a carbonated beverage when opening, it's container releases a mass of rising bubbles.

Can rising magma change composition before reaching the surface?
Yes. If the magma stops in a magma chamber long enough it can change composition through two mechanisms:fractional crystalization, where minerals with lower melting points crystallize and sink to the bottom og the chamberMelting of srrounding rock, which then become part of the magma.

How do you change sedimentary rocks into metamorphic rocks?
Sedimentary rocks could become metamorphic rocks if they are exposed to extreme heat and pressure deep in the Earth's crust. The rocks could come to the surface by volcanic activity or rising magma.
What type of rock can change into an igneous rock?
Igneous rocks can change into metamorphic rocks from great heat and pressure as all other rocks can, melt into magma, the molten rock, and erode into sediment, which are rock fragments.
Heat and pressure deep beneath earth's surface can change any rock into?
