2.5 Formation of MineralsPhysical Geology

Most of the minerals that make up the rocks around us formed through the cooling of molten rock known as magma. At the high temperatures that exist deep within Earth some geological materials are liquid. As magma rises up through the crust either by volcanic eruption or by more gradual processes it cools and minerals crystallize.

WeatheringWikipedia

Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment. New or secondary minerals develop from the original minerals of the rock. In this the processes of oxidation and hydrolysis are most important. Chemical weathering is enhanced by such geological agents as the presence of

ROCKS AND ROCK- FORMING PROCESSES

METAMORPHIC ROCKS (6) The minerals occurring in metamorphic rocks depend on the minerals present in the original rock and the nature of the metamorphic processes that occur. Metamorphic rocks commonly contain abundant silicate minerals many of these silicate minerals are minor or nonexistent in rocks crystallizing from magma. This fact is

The rocks may be made up entirely of one mineral or various minerals and their sizes are determined by the cooling process. Igneous rocks are of two types intrusive and extrusive. Intrusive igneous rocks are formed when the magma cools off slowly under the earth s crust and hardens into rocks.

The Rock Cycle

Like most Earth materials rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation breakdown and reformation of a rock as a result of sedimentary igneous and metamorphic processes. All rocks are made up of minerals.
