Part A
What are the rock forming minerals?
Answer
Rock-forming minerals are the common, naturally occurring inorganic substances that constitute the bulk of the Earth's crustal rocks. Examples include quartz, feldspar, mica, amphiboles, pyroxenes, and olivine.
Explain the term metamorphism.
Answer
Metamorphism is the solid-state recrystallization of pre-existing rocks (igneous, sedimentary, or metamorphic) due to changes in physical and chemical conditions, primarily temperature, pressure, and chemically active fluids. This process occurs deep within the Earth's crust without melting the rock, resulting in new mineral assemblages and textures.
