Introduction
Metamorphic rocks classified by their properties and formation
8 words
Main Body
Metamorphic rocks characterised by poor quality mineral composition and less aquiferous properties. They have porous interior with loss of material at surface.
Nature made of Origas (geological origin):
i) Igneous - formed from volcanic activity, then solidified after cooling
ii) Sedimentary - formed from call compaction and lithification of deposited material
iii) Metamorphic - formed through pressure, temperature action by local crust activity below mountain ranges
All rocks follow an essentially cyclical pattern in their formation, progressing from one stage to another.
Conclusion
Hence, all rocks are essentially in a cyclical pattern forming from one stage to another.
