What metamorphic rock is formed from greywacke?
Greywacke can metamorphose into a rock known as schist. Schist is a coarse-grained metamorphic rock with a foliated texture, often containing minerals like mica, quartz, and feldspar.
How is greywacke different from scoria?
Greywacke is a type of sedimentary rock that is primarily composed of sand-sized grains of various minerals and rock fragments, while scoria is an igneous rock that is formed from the solidification of lava with a high gas content. Greywacke typically has a gritty texture and can be formed in marine or terrestrial environments, while scoria is porous and has a vesicular texture due to the presence of gas bubbles during cooling.
What sedimentary rock turns into epidosite?
Sedimentay rocks like greywacke of arkose, in presence of high fluid-rock ratio, can be converted to epidosite. The feldspars present in these rocks are altered to epidote & these rocks contain already quartz which together form epidosites. Epidosites also occur as part of metasomatic skern association. sedimentary dolomite associated with ultramafics often show contact zone metasomatism, in which Ca- minerals are often altered into epidote. Quartz is produced as by products in the reactions.
Why is air less dense than Earth's rocks?
Air is less dense than Earth's rocks because air is made up of molecules that are spaced further apart and have lower mass compared to the atoms and molecules that make up rocks. Rocks have a higher density due to the tightly packed arrangement of atoms and molecules, resulting in a higher mass per unit volume compared to air.
How igneous rock can become sedimentary rocks?
Igneous rock can become sedimentary rocks through the process of weathering and erosion, where the igneous rock is broken down into smaller pieces and transported by wind or water. These pieces then accumulate and are compacted and cemented together to form sedimentary rocks over time.
What is the rock-sub category for a Greywacke rock?

Is graywacke a sedimentary rock?
Yes, graywacke is a type of sedimentary rock. It forms from a mixture of sand and silt-sized grains, along with gravel-sized particles, which are commonly deposited in marine environments such as beaches and deep-sea fans. Graywacke typically has a gray color and is known for its toughness and resistance to weathering.
