contact metamorphism
What else can I help you with?
Magma reaches the earths surface as a result of the process called?
Magma reaches the Earth's surface through a process called volcanic eruption. This occurs when pressure builds up underground and forces the magma to flow and eventually break through the Earth's surface. Once the magma reaches the surface, it is then called lava.
What rock forming process occurs when hot magma forces its way into rocks?
When hot magma forces its way into rocks, it can cause contact metamorphism. This process involves the high temperatures and pressure of the magma altering the surrounding rocks, changing their mineral composition and creating new rocks like marble or quartzite. Additionally, the rocks affected by the intrusion of magma may exhibit new textures and structures from the heat and chemical reactions.
Magma that forces its way into rocks and hardens is called a extrusion or fault or unconformity or intrusion?
Magma that forces its way into rocks and hardens is called intrusion.
What rock forming process occures when hot magma forces its way into rock?

What occurs when heat from nearby magma causes changes in the surrounding rocks?
When heat from nearby magma causes changes in surrounding rocks, a process called contact metamorphism occurs. This process includes changes in rock texture and mineral composition due to the high temperature and pressure from the magma. This usually results in the formation of new minerals and textures within the rocks.
What is it called when metamorphism occurs due to heat generated by magma?
When metamorphism occurs due to heat generated by magma, it is called "contact metamorphism." This process typically happens when surrounding rocks are heated by the proximity of molten magma, leading to changes in mineral composition and texture. The effects are usually localized around the intrusion of magma, resulting in the formation of metamorphic rocks such as hornfels.
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.
How does an intruding magma body make room for itself during emplacement?
An intruding magma body makes room for itself during emplacement by causing the surrounding rocks to deform and fracture. This process occurs through processes such as dilation, where the pressure of the magma forces the surrounding material to expand, and brittle failure, where the rocks break apart to accommodate the incoming magma. As the magma rises, it can also create a network of cracks and fissures, allowing it to move upwards more easily. Ultimately, this creates a space for the magma to occupy as it solidifies into igneous rock.
What is the process through which single parent magma can form rocks with different compositions?
The process through which single parent magma can form rocks with different compositions is known as fractional crystallization. It occurs as the magma cools and solidifies, with different minerals crystallizing at different temperatures. As these minerals crystallize and settle out of the magma, they can form different rock compositions depending on the minerals that have formed. This process can produce a range of rock compositions from a single parent magma.
What do you call the process that occurs when magma cools and the ions join in very specific patterns?
I could be wrong. But crystalization is what I would say.
What process occurs when a more dense plates sink beneath a less dense plate?

Magma can change form when?
Magma can change form when it cools and solidifies to become igneous rock. This process typically occurs underground, allowing the magma to cool slowly and crystallize into different types of igneous rocks such as granite or basalt.
