Metamorphic rock
A metamorphic rock
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
heat and pressure, but without melting.
sedimentary rocks
A sedimentary rock changes into a metamorphic rock when there is heat, pressure, and time. -over a long period of time
Well, first before the sediment can become to a metamorphic rock, it has to create into a sedimentary rock or an igneous rock, Then the rocks go under the ground and is under tons and tons of pressure, which fosters heat build up, and this causes them to change.
It would undergo metamorphism, if the heat and pressure are sufficient.
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.
Usually it is metamorphic rocks that are formed by heat and pressure, but sedimentary rocks can too. Usually, the word 'sedimentary' means 'of sediments' which means that it is composed of lots of layers upon layers compacting down. In that case, pressure is essential, but heat isn't always needed.
Sedimentary rocks could become metamorphic rocks if they are exposed to extreme heat and pressure deep in the Earth's crust. The rocks could come to the surface by volcanic activity or rising magma.
sedimentary rock
Granite is an intrusive igneous rock that can become exposed at the surface, eroded, and form sedimentary rock through lithification of sediments. It can also become the metamorphic rock gneiss by being exposed to extreme pressures and additional heat from mountain building processes.
No
Heat & pressure
All sedimentary rock change with heat and pressure. They turn into metamorphic rocks.
Metamorphic rocks.
1. Sedimentary will only change to metamorphic, not the other way around. 2. Sedimentary rock will change to metamorphic by means of heat and pressure.
