Which process would change metamorphic rock to igneous rock
The process that would change metamorphic rock to igneous rock is called melting and solidification.
The process that changes metamorphic rock to igneous rock is called "igneous intrusion." This process occurs when molten rock, called magma, pushes its way into existing metamorphic rocks and cools, solidifying to form igneous rocks.
To understand this process, we need to know a bit about the rock cycle. The rock cycle is a continuous process that involves the formation, erosion, and transformation of rocks through various geological processes.
First, let's start with metamorphic rock. Metamorphic rocks are rocks that have been subjected to high heat and pressure, causing them to recrystallize and change their form. This can happen deep underground when rocks are exposed to intense heat and pressure due to tectonic activity.
On the other hand, igneous rocks are formed from the cooling and solidification of molten magma. Magma is formed when the Earth's mantle, which is located below the Earth's crust, melts due to high temperatures and pressure. When magma rises to the Earth's surface through volcanic activity, it cools and solidifies to form igneous rocks.
Now, let's delve into the process of how metamorphic rock can be transformed into igneous rock through igneous intrusion. This occurs when magma, which is molten rock, invades or intrudes into existing layers of metamorphic rock. As the magma cools down and solidifies within the metamorphic rock, it forms igneous rocks.
The intrusion of magma can occur through various processes, such as when magma pushes its way through cracks and fractures in the Earth's crust or when it infiltrates existing metamorphic rock layers during tectonic activity.
To sum it up, the process of transforming metamorphic rock into igneous rock occurs through igneous intrusion, where molten magma invades or intrudes into existing metamorphic rock, cooling and solidifying to form new igneous rocks.
