What clues do you have on how minerals form?
Minerals can form through a variety of processes, including crystallization from magma, precipitation from water (such as in hot springs or the ocean), or through metamorphism where existing minerals change due to temperature and pressure. The environment in which minerals form, such as the temperature, pressure, and chemical composition of the surrounding material, plays a key role in determining their characteristics. Additionally, factors such as the presence of specific elements, the rate of cooling, and the availability of space for crystal growth can influence mineral formation.
What minerals are in the upper mantle?
The upper mantle is mainly composed of minerals such as olivine, pyroxene, and garnet. These minerals form under high temperature and pressure conditions in the Earth's interior, contributing to the solid composition of the upper mantle.
Where do rocks and mineral come from?
The minerals are made up of various atoms which are joined by strong chemical bonds in a very disciplined manner. Now at a particular pressure and temperature atoms joined together to form a particular mineral which is stable at that pressure-temperature. Rock is an aggregate of various minerals e.g. granite has orthoclase feldsper,quartz,small amount of mica etc. in a particular texture which together helps to stabilize the whole system in normal pressure-temperature.
What two things make possible sedimentary and metamorphic rocks to form deep underground?
High pressure and high temperature deep underground make it possible for sedimentary rocks to undergo metamorphism, which leads to the formation of metamorphic rocks. These conditions cause the existing minerals in sedimentary rocks to recrystallize and form new minerals, changing the rock's texture and composition.
How are minerals formed in igneous and metamorphic rocks?
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 is important in the formation of minerals?
Minerals are formed through various geological processes like crystallization from magma, precipitation from solutions, metamorphism, and pressure and temperature changes. Factors like chemical composition, temperature, pressure, and time play crucial roles in the formation of minerals. The environment in which the minerals form can also impact their characteristics.
Where would you find minerals that are stable under low temperature and pressure?
At the earth's surface. The deeper you go in the earth, the higher the pressure and temperature, and the minerals that are stable under low temperature and pressure become unstable, and turn into other minerals that are stable under those conditions.
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.

What change has occurred to metamorphic rock?
Metamorphic rock has undergone changes in temperature, pressure, or chemical composition, causing it to recrystallize and form new minerals.
What minerals form when rock is metamorphosed?
Minerals such as mica, quartz, feldspar, and garnet can form when rock undergoes metamorphism. These minerals typically form in response to changes in temperature and pressure, resulting in the transformation of the original minerals into new ones. The specific mineral assemblages that form depend on the composition of the original rock and the conditions of metamorphism.
When temperature and pressure change what can happen to the minerals and rocks?
They can change into coal
When temperature and pressure change what happens to the minerals in the rocks?
They can change into coal
What minerals are in the upper mantle?

Why are minerals that form below Earth's surface unstable at Earth's surface?
Minerals that form below Earth's surface are unstable at the surface because they are often formed under high pressure and temperature conditions, which are different from the lower pressure and temperature conditions found at the surface. As a result, these minerals can undergo chemical reactions or physical changes when exposed to the new environmental conditions at the surface, causing them to break down or transform into more stable minerals.
What forms when minerals dissolved in water solution crystallize?
A Chemical Rock
What are some common metamorphic minerals found in rock formations?
Some common metamorphic minerals found in rock formations include quartz, mica, garnet, and amphibole. These minerals form as a result of high pressure and temperature changes within the Earth's crust.
