Answer: Gneiss
Explanation: Gneiss is a metamorphic rock formed from shale at very high temperature and pressure condition. They exhibit a preferred alignment or orientation of platy minerals called foliation. They are coarse grained and exhibit gneissose banding. They are formed from highest grade regional metamorphism with temperature between 450 - 600 degree celcius and pressure between 800 - 1000 mega pascal. They generally occur in cores of fold mountain belts where mountain ranges have been eroded.
Earthquakes and tremors near it, and smoke
Answer:
a and c
Explanation:
Basalt pillows occur when the basalt flows into the sea and the hot lava's contact with the cold sea water, the thermal shock, shapes the basalta into a rounded (pillow-like) shape, cooling the surface while a mass of Basalt is kept inside. For this reason, we can say that basalt pillows are an underwater shape, characterized as lens-shaped masses surrounded by cooled shells.
