What happens if the magma has the same density as the rock around it?
If the magma has the same density as the rock around it, it will likely stay in place without rising or sinking. This can lead to the formation of magma chambers or magma pockets within the surrounding rock, potentially resulting in volcanic activity if pressure builds up.
What forces magma to Earth's surface?
Generally, its higher temperature. The temperature of a rising magma is generally higher than the temperature of its surrounding rocks. Because of its higher temperature, it is also lighter compared to the surrounding rocks (it has a lower density), so it rises. Imagine a hot air balloon: it rises because the air inside the balloon is heated, heating the air lowers its density (makes it lighter). As long as the density of the air inside the balloon is lower than the density of the air outside the balloon, the balloon rises.
Magma flows in the mantle like a river and can form magma pools?
Magma flows in the mantle due to its high temperature and lower density compared to the surrounding rock, but it moves much more slowly than water in a river. As magma rises towards the surface, it can accumulate in magma chambers or pools before erupting as lava onto the Earth's surface.
What two things drive out magma?
Magma is driven out of the Earth's interior by a combination of pressure buildup beneath the surface and buoyancy of the molten rock due to its lower density compared to the surrounding solid rock. Additionally, the presence of volatile gases, such as water vapor and carbon dioxide, can also contribute to the force that drives magma to the surface during volcanic eruptions.
What would cause a metamorphic rock to surround magma?
The contact metamorphism process occurs when magma intrudes into surrounding rock, causing the adjacent rock to be heated and recrystallize into a metamorphic rock. The heat and pressure from the magma alter the mineral composition and texture of the surrounding rock, resulting in the creation of a metamorphic rock zone around the magma.

What will be happen after magma form?
After magma forms, it will typically rise towards the Earth's surface due to its lower density compared to surrounding rock. As it reaches the surface, it may erupt as lava through a volcano or form intrusive igneous rock formations beneath the surface.
Does magma erode igneous rocks inside a volcano?
In a way. A magma is hotter then the surrounding rock, that's why the magma is molten and the rock is not. But because of this, some heat of the magma is melting the surrounding rock. You might want to classify this as erosion, but it's simply the melting of the rock surrounding the magma.
Why might molten rock rise and sink beneath the earths surface?
changes in buoyancy due to changes in density differences between the magma and surrounding rock.

Magma from deep inside earth rises toward the surface because?
Magma from deep inside the Earth rises toward the surface because of its lower density compared to the surrounding rocks, creating buoyancy forces that drive the magma upwards. Additionally, the pressure from gases within the magma can also contribute to its ascent.

What is magma sill?
A magma sill is a planar sheet of magma which is parallel to the surrounding rock.

Which type of rock is formed when magma forces itself into surrounding undergound rock?
Igneous rock is formed when magma forces itself into surrounding underground rock and cools and solidifies. The surrounding rock is heated and metamorphosed but does not fully melt in this process.
Is magma less dense then the surrounding rock?
yes
