What role does heat play in creating new minerals or new crystalline structures in metamorphic rocks?

The heat comes from magma that is deep inside the earth, sedimentery rock is heated and squashed into metamorphic rock.

Why non silicate minerals have wider variety of crystalline structures than silicate minerasls do?
Non-silicate minerals contain oxygen and native elements. They have metallic and non-metallic lusters, and are very common.
Is metamorphic a type of mineral?
Metamorphic is a group of rocks with similar characteristics. There are minerals in the rocks so they could be considered made of minerals but they are not minerals themselves.
Why do minerals that have the nonsilicate crystalline structure called closest packing have high density?
Minerals of a nonsilicate crystal have very high densities because their crystal structures are based on the packing of atoms that are as close together as possible. This structure is called this closest packing.
What mineral forms stalactites and stalagmites?
A metamorphic form of limestone is marble.
Why do minerals in metamorphic rocks often rearrange in layers?
The alignment of minerals into bands (foliation) is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.
Where are crystalline minerals found?
In all three rock types: igneous, sedimentary, and metamorphic. By definition, a mineral has a crystalline structure, and rocks are composed of combinations of minerals. Rocks with interlocking crystalline mineral structures are usually igneous or metamorphic.
What crystalline structure would a metamorphic rock have?
they have rocks and minerals
What are the 6 main crystalline structures of silicate minerals?

If silicon bonded with three oxygen atoms how might the crystalline structures of silicate minerals?
If silicon bonded with three oxygen atoms, the crystalline structures called framework would be three-dimensional, and silicate minerals will become lighter.
Component that changes in size or shape when metamorphic rocks are formed?
Minerals(inorganic solids with a crystalline structure) change in size or shape under the intense heat and pressure to form metamorphic rocks.
Do all minerals have crystalline structures?
yes i am pretty sure they do! I am learning about the lithosphere and rocks and minerals and stuff and i think that is what the teacher said!
When minerals form slowly without space restrictions they will develop what?
When minerals solidify they form crystalline structures.
Why are feldspars considered to be minerals even though their compositions can vary?
they are inorganic and have crystalline structures.
What is the the difference between rocks and minerals?
Rocks are solid substainces that are made of 2 or more minerals and can have organic matter in them as well. On the other hand, minerals are naturally formed inorganic solids that have definite crystalline structures. Rocks and minerals are made through different processes.
Why marble is not a mineral?
Marble is in fact a type of metamorphic rock. Rocks are aggregate of one or many different kinds of minerals with no definite chemical composition and a specific crystalline structure that all minerals have, so marble is not a mineral.
