A) Black cotton soil of North-West India was formed by the weathering of basaltic lava rocks
B) Sedimentary rocks are distinguished from other types of rocks by the presence of distinct layers
C) Granite has large crystals of quartz, feldspar and mica in it
D) A metamorphic rock is softer and less compact than its original type
Correct Answer: D
Solution :
The main thing about metamorphic rocks is that they are shaped by great heat and pressure. Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks. They're made of different minerals than other kinds of rocks and have a wide range of colour and luster. They generally show signs of stretching or squeezing, giving them a striped appearance.
