Geology

The most valuable metal in the Earth's crust can vary depending on a number of factors such as current market demand, availability, and the cost of extraction. Precious metals, such as gold, platinum, and silver, have historically been highly valued due to their scarcity and unique properties, and are often associated with luxury items and financial instruments.

Fault is a fracture or crack where two rock blocks slide past one to another. If this movement may occur rapidly, it can be causes earthquike or slowly, in the form of creep.Types of faults include strike-slip faults, normal faults, reverse faults, thrust faults, and oblique-slip faults.

Weathering is the combination of processes that breaking down of rocks, soil and minerals, eventually transforming into sediment. On the other hand, disintegration or alteration of the rock surface in its natural or original position through physical, chemical and biological processes induced or modified by wind, water and climate.

Bowen's reaction series is based on observations and experiments of natural rocks, the crystallization sequence of typical basaltic magma change as they cool. It is a sorting tool according to the temperature at which they crystallize common magmatic silicate minerals.

The rock cycle basic definiton is transitions among the three main rock types, which are metamorphic, igneous and sedimentary rocks. Each of the rocks can be altered when they are force out equilibrium conditions.The rock cycle describes how the three rock types are interrelated and how processes change from one to another over time.The rock cycle
