Metamorphic rocks that don't have layers?
Metamorphic rocks without visible layering are typically formed under conditions of high temperature and pressure that cause the minerals within the rock to recrystallize. This may result in a homogeneous texture without distinct layers or bands. These rocks may still exhibit foliation or other textures that indicate their metamorphic origin, even if they lack visible layering.
What are the two categories of metamorphic rocks?
Metamorphic rocks can be categorized into two main categories: foliated and non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of mineral grains, while non-foliated metamorphic rocks lack this layered structure.
Metamorphic rocks in which minerals are NOT aligned within the rock are called?
Metamorphic rocks in which the minerals show no alignment are called non-foliated metamorphic rocks.
Changed-over rocks are called?
Metamorphic Rocks
Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
What describes the thin flat layering in most metamorphic rocks?
The thin flat layering found in most metamorphic rocks is called foliation
What describes the thin flat layering found in most metamorphic rocks?
The thin flat layering found in most metamorphic rocks is called foliation, and it is formed due to the alignment of mineral grains or the presence of alternating layers of different mineral compositions. Foliation is a common feature in rocks that have undergone high pressure and temperature conditions, leading to the development of a layered structure.

What are metamorphic rocks with grains arranged randomly said to be?
Metamorphic rocks with grains arranged randomly are said to be non-foliated. This means they do not have a layered or banded structure like foliated metamorphic rocks. Examples include marble and quartzite.

Metamorphic Rocks
Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
Changed rocks are called?
Changed rocks are called metamorphic. Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, through the use of heat and pressure.Metamorphic rocks
Texture term for metamorphic rocks that lack layering?
Non-foliated metamorphic rock, like quartzite and marble.
What rocks are formed from high temperature and pressures?
Rocks formed from high temperature and pressure include metamorphic rocks such as marble, schist, and gneiss. These rocks are created deep within the Earth's crust through the transformation of existing rock types under intense heat and pressure conditions.
What is the difference between stratification and foliated rocks?
Stratification results in sedimentary rock due to the deposition of organic and inorganic particles. Foliation is a texture in metamorphic rocks which is a result of heat and pressure, and results in constituent minerals appearing banded or lamellar, due to realignment.
