What b do minerals sometimes form in metamorphic rock?
Minerals in metamorphic rocks can form due to changes in temperature and pressure, which cause existing minerals to recrystallize or new minerals to grow. The specific minerals formed depend on the original composition of the rock and the conditions under which the metamorphic process occurred.
These rocks form from previously existing rocks that have been altered by heat and pressure?
These rocks are metamorphic rocks. They form when existing rocks (igneous, sedimentary, or other metamorphic rocks) undergo high temperatures and pressure deep within the Earth's crust, causing their minerals to recrystallize and new minerals to form. Metamorphic rocks can have distinct textures and structures depending on the intensity of the heat and pressure they experienced.
Name three common evaporite minerals?
Evaporates are found where there is water, such as soil. Three common evaporate minerals found in soil are Anhydrite, Mirabilite, and Thenardite.
What are three common evaporite minerals?
Three common evaporite minerals are halite (rock salt), gypsum, and calcite. These minerals form from the evaporation of water containing dissolved ions, leading to the precipitation of these minerals on the Earth's surface. Evaporite minerals are often found in arid environments like salt flats and dried-up lake beds.
What does not change the form of existing rock?
When there is no weathering. When there there are no intrusions of magma beneath rock no metamorphic rock will form. But, this is impossible as the Earth atmosphere and interior forces are so dynamic. Over time all rocks will undergo some kind of change.
How do vein minerals form?
Vein minerals are those that form in fissures in the existing rock, either thru deposition by mineral saturated hydrothermal fluids, or injection of magma and subsequent cooling.
What name is given to the process where hot mixtures of water and dissolved substances react with existing minerals to form minerals?
The process where hot mixtures of water and dissolved substances react with existing minerals to form new minerals is called hydrothermal mineral alteration or hydrothermal alteration. This process commonly occurs in hydrothermal vents or deep in the Earth's crust.

Why oceanic water absorb so many minerals in it?
Ocean water absorbs a lot of minerals because water is such an excellent solvent for so many substances. Combine with that, the abundance of existing dissolved materials that can form soluble salts with many existing minerals and you have an excellent environment for dissolving minerals that start out as oxides.
What do minerals need to form?
Minerals form through a process involving the cooling and crystallization of molten rock, the precipitation of dissolved substances from water solutions, or the alteration of pre-existing minerals due to changes in temperature, pressure, or chemical environment. These processes help mineral components come together in a specific arrangement to form a crystalline structure.
How are mineral formed in igneous and metamorphic?
Minerals form in igneous rock as magma or lava cools. The minerals will form from the available chemicals in the magma as their crystallization temperature is reached. The sequence of mineral crystal formation from magma is described in the Bowen's Reaction Series. Metamorphic rock minerals are aligned, altered, or recrystallized from existing rock minerals due to the effects of heat and/or pressure.

What minerals originate as a product of chemical weathering?
Common minerals that originate as products of chemical weathering include quartz, clays (such as kaolinite), iron oxides (such as hematite), and carbonates (such as calcite). These minerals form as a result of the breakdown and alteration of pre-existing minerals by chemical reactions with water, gases, and organic acids.
