What are some non-examples of metamorphic rocks?
Sandstone, limestone, and shale are non-examples of metamorphic rocks because they are sedimentary rocks formed from the accumulation and compaction of sediments, rather than being subjected to the high pressure and temperature conditions required for metamorphism. Additionally, granite, which is an igneous rock formed from the cooling and solidification of magma, is another non-example of a metamorphic rock.
What is an example of a metamorphic rock that is formed when heated under pressure?
Slate is silt changed under pressure.
What is an example of foliation?
An example of foliation is the parallel alignment of minerals in a metamorphic rock, such as schist or gneiss. This alignment results from the pressure and temperature conditions during the rock's formation, creating a layered or banded appearance.
How does metamorphic rock form example?
Metamorphic rocks form from existing rocks that are subjected to high heat and pressure, causing changes in their mineral composition and texture without melting. For example, limestone can be metamorphosed into marble through the process of recrystallization under intense heat and pressure beneath the Earth's surface.
Would quartzite or sandstone break more easy?
A brittle material is one that fails by fracturing after only a very small amount of plastic strain has occurred. Sandstones tend to be made up of quartz and feldspars which are themselves brittle. However sandstone and many other materials are only thought of as brittle because we are used to dealing or working with them at the pressure and temperature conditions present at the Earth's surface and can actually be either brittle or ductile (significant plastic deformation can occur before ultimate rupture) depending on the temperature, confining pressure and strain rate applied to it. In general at low confining pressures and temperatures (i.e. near the Earth's surface), sandstone will fail in a brittle fashion. However as the temperature and or confining pressure increases it becomes increasingly ductile.
What kind of rock is NOT an example of metamorphic rock?
Alot of them. Basalt, Granite, sandstone, siltstone etc

What is the def Metamorphic rock?
Metamorphic rock is rock that has changed as a result of constant heat, pressure, or both. One good example is granite.
Sandstone is example of what type of rock?
Sandstone is an example of sedimentary rocks.
What type of rock has distinct bands?
Sedimentary rocks such as sandstone and limestone often exhibit distinct bands or layers due to the deposition of sediments over time. Metamorphic rocks like gneiss and schist can also display banding as a result of intense heat and pressure causing minerals to align in layers.
What is an example of foliation?
An example of foliation is the parallel alignment of minerals in a metamorphic rock, such as schist or gneiss. This alignment results from the pressure and temperature conditions during the rock's formation, creating a layered or banded appearance.
What is an example of metamorphic igneous and sedimentary rocks?
Metamorphic rock: Marble, formed from the metamorphism of limestone. Igneous rock: Granite, formed from the cooling and solidification of molten magma. Sedimentary rock: Sandstone, formed from the compaction and cementation of sand grains.
Does igneous rock have to become sedimentary rock before it can become metamorphic rock?
No, igneous rock can undergo metamorphism without becoming sedimentary rock first. Metamorphism can occur in any rock type (igneous, sedimentary, or metamorphic) when exposed to high temperature and pressure, leading to the formation of new minerals and textures.
Is quartzite a igneous rock or a sedimentary rock?
Quartzite is a metamorphic rock, which means it was once a different type of rock (such as sandstone) that underwent intense heat and pressure to form quartzite. It is composed primarily of quartz grains.
Is marble and limestone an example of a metamorphic rock and its parent rock?
Yes, marble is a metamorphic rock formed from limestone, which is the parent rock. This process occurs due to the recrystallization of minerals within the limestone under high pressure and temperature conditions.
How could metamorphic rock become a sedimentary rock?
When sedimentary rock undergoes enough heat and pressure, it becomes metamorphic rock. A classic example of this is when shale becomes slate.
