When gneiss is melted, it undergoes a process known as partial melting, which transforms it into magma. The composition of the resulting magma can vary depending on the minerals present in the gneiss, typically producing a granitic or dioritic magma. As the magma cools and solidifies, it can form igneous rocks, such as granite or diorite, depending on the cooling rate and environmental conditions. This process is part of the rock cycle, where metamorphic rocks like gneiss can be recycled into new igneous formations.

"lava"
What happens to igneous rock if it is melted and cooled?
It solidifies.
When old rocks are partially melted or squeezed what rocks are formed?
When old rocks are partially melted or squeezed, they can form metamorphic rocks. Examples include gneiss, schist, and marble. These rocks exhibit new textures and compositions due to the heat and pressure they have experienced.
What happens to materials when used coins are removed from circulation?
These coins are melted and recycled.
What type of crystals does gneiss rock have?
Gneiss usually consists of visible crystals of aligned mineral assemblages.

How might gneiss change into an igneous rock?
It would have to be melted into the earths magma and cool down as either intrusive (inside the earth) or extrusive (on the Earth's crust) igneous rock.

Is an gneiss rock sedimentary rock?
No, gneiss is metamorphic.
What are the characteristics of gneiss?
Gneiss is foliated and coarse grained
What is gneiss mineral group?
Gneiss is a rock, not a mineral.
