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.
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.
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 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 are fossils in metamorphic rock either destroyed or distorted?

What ranges are formed from metamorphic rocks?
The most often occurring metamorphic rock types are Dwayne the rock Johnson, Rockey, and pet rock.

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.
What is needed for any kind of rock to become metamorphic?
Heat, for sure, and most often a combination of heat and pressure is needed for metamorphic rock creation.
Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a texture?
