How would Sedimentary rock turn to metamorphic?
Sedimentary rock that is exposed to heat and pressure will be changed to (metamophised) into metamorphic rock. This is often associated with volcanic activity. An example is limestone, when exposed to the pressure and heat can be changed to marble.
Why are fossils in metamorphic rock either destroyed or distorted?
Fossils in metamorphic rock are often destroyed or distorted because the intense heat and pressure involved in the formation of metamorphic rock can alter the physical and chemical properties of the fossils, making them unrecognizable. This process can also cause the original structures of the fossils to be crushed or deformed, leading to their destruction or distortion.
What are the visual characteristics that distinguish a metamorphic rock from other types of rocks, and how does a metamorphic rock typically appear in terms of its physical features and textures?
Metamorphic rocks are distinguished by their unique textures and structures, which are formed through intense heat and pressure. These rocks often have distinct layers or bands, known as foliation, and may contain minerals that have been rearranged or recrystallized. In terms of physical features, metamorphic rocks can appear shiny, smooth, and sometimes have a striped or swirled pattern. Their textures can range from fine-grained to coarse-grained, depending on the specific conditions under which they were formed.
What would distinguish marble from Schist?
Marble is a nonfoliated metamorphic rock made of carbonate minerals, particularly calcite. It is formed by the metamorphism or limestone. Gneiss is a foliated metamorphic rock made of silicate minerals such as quartz and feldspars, and micas. It forms from the metamorphism of granite or schist.
Is fluorite metamorphic?
Fluorite is a commonly found mineral that forms from hydrothermal processes and is often associated with rocks of various origins, including sedimentary, igneous, and metamorphic rocks. While it can be found in metamorphic environments, fluorite itself is not considered a metamorphic rock.
What are the kinds of earth rocks on earth?
The three main types of rocks on Earth are igneous, sedimentary, and metamorphic rocks. Igneous rocks are formed from the cooling and solidification of magma or lava. Sedimentary rocks are created from the accumulation and compaction of sediment particles. Metamorphic rocks are rocks that have undergone changes in temperature and pressure, often deep within the Earth's crust.
What are quantitative physical properties?
Quantitative physical properties are measurable characteristics of a substance, such as density, mass, volume, and temperature. These properties can be expressed as numerical values and often involve units of measurement. Quantitative physical properties help define and distinguish different substances based on their specific characteristics.
What are the properties of metamorphic rocks?
Metamorphic rocks are formed from existing rocks that undergo changes due to heat, pressure, and chemically active fluids. They often exhibit foliation, which is the alignment of mineral grains, or may appear non-foliated, depending on their formation conditions. Common properties include increased density and hardness, as well as the presence of new minerals that form under metamorphic conditions. Examples include schist, gneiss, and marble.
Name four kinds of metamorphic rock?
Four kinds of metamorphic rock include schist, gneiss, marble, and quartzite. Schist is characterized by its layered texture and is often formed from shale. Gneiss typically exhibits banding and is derived from granite or volcanic rock. Marble forms from limestone and is known for its use in sculptures and architecture, while quartzite originates from sandstone and is highly resistant to weathering.
What are the properties of gneiss?
gneiss has many properties depending on the type of gneiss it is but some common properties are fine or coarse grains, metamorphic "bands" on the rock, and it's composition which is feldspar,quartz, mica, and hornblende.

Why do metamorphic rocks often formed deep under the surface of the earth?
Metamorphic rocks are often found deep under the earth's surface because metamorphic rocks form from heat and pressure. Therefore, they form while they are under the earth's surface.

Why metamorphic is an appropriate name for slate and schist?
The term "metamorphic" refers to rocks that have undergone transformation due to heat, pressure, or chemically active fluids. Slate and schist are both classified as metamorphic rocks because they originate from the alteration of sedimentary rocks—slate from shale and schist from various parent rocks, often including schistosity. This transformation results in distinct mineral alignments and textures, giving them unique physical properties. Thus, the name "metamorphic" aptly describes their origin and the processes they have undergone.
Is metamorphic used in toothpaste gum glue and soap?
Metamorphic rocks themselves are not used in toothpaste, gum, glue, or soap. However, some minerals derived from these rocks, such as talc, may be used in certain products for their properties. Toothpaste and soap typically contain various ingredients, including abrasives, surfactants, and moisturizers, rather than metamorphic materials. Gum and glue often have synthetic or natural polymers as their primary components.
What ranges are formed from metamorphic rocks?
The most often occurring metamorphic rock types are Dwayne the rock Johnson, Rockey, and pet rock.
