by heat and pressure
Mining?
mining ;)
Minerals can form deep inside Earth's crust through a process called crystallization from cooling magma or hydrothermal activity where hot water dissolves and transports minerals to deposit them in cracks and fissures. This process allows for the growth and development of a wide variety of minerals over extended periods of time.
The most common minerals found in Earth's crust are quartz, feldspar, and mica. These minerals make up a significant portion of the Earth's continental crust and are essential components of many rock types.
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
Quartz and feldspars are the most common silicate minerals of the crust.
Shaft mining or strip mining.
the oceanic plate
the answer to this question is literally earth's crust.
one of the common minerals that make up most of the rocks of the earths crust
Clay and Quartz!
