_______ is a type of metamorphic rock distinguished by its banding, resulting from the separation of various rock types, often light and dark silicates.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Gneiss.
- Metamorphic Rocks: These are those types of rocks that result from the alteration of pre-existing rocks in response to changing environmental conditions, such as variations in temperature, pressure, and mechanical stress.
- Gneiss: It is a metamorphic rock form characterized by banding caused by the segregation of different types of rock, typically light and dark silicates. The "gneissic texture" is the segregation of light and dark minerals.
