Metamorphic Rock
Metamorphic rocks are formed from other types of rocks. The original rock is exposed to conditions such as heat or pressure. Carbon turning to diamonds while under extreme pressure is an example of a metamorphic rock.

What does slate turn into if heated and squashed?
If slate is sufficiently heated and compressed it becomes phyllite.
What can you infer about metamorphic rocks from their names?
That they have undergone some form of change.

How can igneous metamorphic and sedimentary rocks become metamorphic rocks?
Im learning this in school, and the answer is look for a "rock cycle" and that answers all questions like yours :)
Is pressure not a metamorphic agent?
Yes, pressure is a metaphoric agent along with heat, and hydrothermal solution. Rocks are classified by the process in which they are formed, meta means change and morph means form.
What causes foliates metamorphic textures?
Heat, along with applied pressures, either from depth of burial or from tectonic forces on rock.
Limestone is the parent rock of the non foliated metamorphic rock called?
Limestone is the parent of rock of non foliated metamorphic. This is a very old type of rock.
Marble can be found in many mountainous places in the world. In particular, it is found mainly in Italy, China, Turkey and Mexico, but also in Belgium, France, Great Britain, Spain, India, and in many parts of the United States, such as Vermont, Colorado, Tennessee and Alabama.
Hope this helps!
What is dehydration depending on geology?
Dehydration in geological terms is a process which occures during metamorphosis. As a rock moves to a higher pressure and temprature, say as it is traveling down a subduction zone the water will gradually be taken out of it. The deeper the rock travels, the more dehydrated it becomes untill eventually there is no water left in it and it is compleatly dry.
What does a metamorphic rock make?
Metamorphic rocks are formed from the alteration of existing rocks due to heat, pressure, or chemical processes deep within the Earth's crust. They can be created from igneous, sedimentary, or existing metamorphic rocks that undergo changes in mineral composition and texture. Examples of metamorphic rocks include marble, quartzite, and schist.
Is Metamorphic rock with no banding called nionfoliated?
Yes, metamorphic rock that lacks banding is referred to as non-foliated. Unlike foliated metamorphic rocks, which have distinct layers or bands due to the alignment of minerals under pressure, non-foliated rocks have a more uniform texture. Common examples of non-foliated metamorphic rocks include marble and quartzite. These rocks typically form under conditions of high temperature and pressure without significant directional stress.
What process must occur to produce a metamorphic rock?
To produce a metamorphic rock, pre-existing rocks (either igneous, sedimentary, or other metamorphic rocks) must undergo metamorphism, which involves exposure to high temperatures, high pressures, and/or chemically active fluids. This process alters the mineral composition and structure of the original rock without melting it. The resulting metamorphic rock often exhibits foliation or distinctive banding due to the alignment of minerals under pressure. Ultimately, the transformation enhances the rock's density and stability.
