subjected to heat and pressure. The intense heat and pressure cause the shale's minerals to recrystallize, giving rise to the fine-grained texture and foliation characteristic of slate.
Metamorphic rocks are formed when existing rocks, either sedimentary or igneous, are subjected to intense pressure and heat deep within the Earth's crust. This process causes the rocks to undergo physical and chemical changes, resulting in the formation of new minerals and textures characteristic of metamorphic rocks.
Metamorphic rock can be formed from sedimentary rocks through the activity of heat and pressure. The intense heat and pressure cause the minerals in the sedimentary rocks to recrystallize, resulting in a new, more compact rock with different properties.
Bituminous coal is consided a sedimentary rock. Anthracite coal is bituminous coal that has been metamorphosed by great pressure and heat and is considered a metamorphic rock.
Igneous or sedimentary rocks are transformed into metamorphic rocks through high pressure, temperature, or both. This process, known as metamorphism, occurs deep within the Earth's crust where rocks are subjected to intense heat and pressure, causing their mineral composition and texture to change without melting.

A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
sedimentary
A sedimentary rock is formed when an igneous rock is subjected to weathering, erosion, compaction, and cementation!
Rock forms through three processes. Sedimentary rocks are formed by the compression of sediment. Igneous rocks are formed when magma crystallizes after melting. Metamorphic rocks are sedimentary and igneous rocks that have been subjected to pressure and heat .
Marble is formed when limestone is subjected to pressure and great heat.
well the sedimentary is formed by heat and pressure
Sedimentary rock is formed when sediments are cemented together due to heat and/or pressure.
heat and pressure
Sedimentary rocks are formed by a four step process called Lithification (1. Erosion, 2. Deposition, 3. Cementation, 4. Compaction). Metamorphic rocks are formed by heat, time, and pressure.
Sedimentary rocks such as shale can change into metamorphic rocks like slate when subjected to heat and pressure. This process, known as metamorphism, alters the mineral composition and texture of the rock without melting it completely.
