Metamorphic rock
Yes, a metamorphic rocks is an existing rock that has been transformed via heat and pressure.
The type of rocks formed from existing rocks that have been squeezed and heated deep inside Earth's crust are called metamorphic rocks. This transformation occurs through a process known as metamorphism, which alters the mineral composition and structure of the original rocks, known as parent rocks. Common examples of metamorphic rocks include schist, gneiss, and marble.
If it is squeezed and heated sufficiently to realign the minerals or form new minerals, it is called a metamorphic rock. If it is squeezed and heated enough to melt, then solidify, it would be called an igneous rock.

When metamorphic rocks are heated, the minerals within the rock may undergo recrystallization, transforming into new minerals. This process can lead to the development of new textures and structures in the rock. However, excessive heat can cause the minerals to melt and reform as igneous rocks.
Sedimentary rocks such as sandstone and shale can form when materials are squeezed together due to pressure from overlying sediments and compaction. Igneous rocks can also form from intense pressure transforming existing rocks, such as with the formation of gneiss from granite under high pressure and temperature conditions.
The type of rocks formed when rock fragments are squeezed together is called sedimentary rocks. These rocks are created through a process known as compaction, where accumulated sediments, such as sand, silt, and clay, are pressed together under pressure over time. Examples of sedimentary rocks include sandstone, shale, and conglomerate.
When rock particles are squeezed and heated, they can undergo metamorphism, a process that alters their mineral composition and texture. This can lead to the formation of new minerals and the development of foliation or banding in the rock. Additionally, the intense pressure and temperature can cause the rock to become more dense and change its physical properties, resulting in metamorphic rocks such as schist or gneiss.
igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).
Nope, because they are created when the Earth pressurizes and heats it (but not to the point of melting). Igneous rocks are created when rocks melt.
