During metamorphism, minerals in a rock can recrystallize to form new minerals, grow larger in size, or reorient themselves to align with the pressure and temperature conditions. This process can result in the rock developing a new texture and mineral composition.

What is the hardness of a metamorphic rock?
The hardness of a metamorphic rock can vary depending on the minerals it contains and the degree of metamorphism it has undergone. Metamorphic rocks can range from relatively soft, such as slate, to very hard, such as marble or quartzite. Hardness is typically measured using the Mohs scale, where harder minerals can scratch softer ones.
What is the hardness of the Metamorphic rock?
Depends on which one. Diamond is a metamorphosed coal/carbon that is the hardest natural substance known. Marble is metamorphosed limestone that is much softer. It's safe to say that all metamorphosed rocks are harder than they were in their pre-metamorphosed form.
What happens when you combine a geoligical agrigant of minerals with its lowest form?
you get dwayne the rock johnson finisher "rock bottom"
What rock is formed when mica is metamorphosed?
Schist is the rock that forms when mica is metamorphosed. Schist is a foliated metamorphic rock that contains minerals such as mica, quartz, and feldspar.
What happens to the component minerals when they are combined in a rock mixture?
When component minerals are combined in a rock mixture, they are physically and chemically bonded together to form the rock. Their individual characteristics can still be observed under a microscope, but they lose their individual identity within the rock.
What is amphibolite made of?
Amphibolite is a type of metamorphosed mafic igneous rock. It is composed largely of minerals such as hornblende and plagioclase.
Shale is a sedimentary rock that can be metamorphosed into slate by what?
Shale can be metamorphosed into slate through the process of low-grade regional metamorphism, which involves heat and pressure causing the minerals within the shale to recrystallize into a fine-grained, foliated structure characteristic of slate.

What are 3 specific types of metamorphic rocks and what was their parent rock?
Slate--metamorphosed shale or mudstone.Phyllite--metamorphosed slate.Quartzite--metamorphosed sandstone.
Name one metamorphosed rock from a sedimentary rock?
Quartzite
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.
What is the crystalline structure of phyllite?
phyllite is a type of metasedimentary rock. The parent rock likely contained clays and/or micas, which have metamorphosed into micas and aligned due to pressure. This shiny surface is produced by the alignment of the minerals.
What happens when heat and pressure is applied to sedimentary rock?
When heat and pressure are applied to sedimentary rock, it undergoes a process called metamorphism. This results in changes to the rock's mineralogy, texture, and structure, transforming it into metamorphic rock. The original sedimentary rock's characteristics are altered, creating new minerals and rock types such as gneiss, schist, and marble.
Granite rock subject to stress it may be metamorphosed into a rock called?
gneiss
Is marble an intrusive rock?
No, marble is a metamorphosed limestone, which itself is a sedimentary rock.
