Metamorphic
they melt
There are three main types of rocks: igneous, sedimentary, and composites. Igneous rocks are formed when sedimentary or composite rocks experience extremes of heat and pressure. Sedimentary rocks are formed when smaller particles are overlaid for extended periods of time. Composite rocks are formed a mixture of elements under pressure.
All rocks can become igneous rocks. With weathering and erosion, an igneous rock can become a sediment. Then with compaction and cementation, it can become a sedimentary rock. With heat and pressure, it will turn into a metamorphic rock. Or it can melt and turn into an igneous rock. There are many more ways rocks can change types... that is the rock cycle.
Intrusive igneous and metamorphic. Intrusive igneous rocks are those that solidify underground. Metamorphic rocks are those that are deep underground and subjected to intense heat and pressure, but remain a solid.
Igneous rocks are volcanic rocks. They are formed when lava/magma dries. Examples of igneous rocks are pumice, obsidian, and granite. Sedimentary rocks are rocks formed when layers of sediment are compacted under immense pressure to form a rock. An example is sandstone. Metamorphic rocks are any rock (igneous, sedimentary, or even metamorphic), is subjected to immense heat and pressure. This causes the rock itself to change to a new rock. Examples are marble and shale.
The 3 basic rock types are igneous, sedimentary and metamorphic rocks, which can all be changed or metamorphosed by heat and pressure.
Metamorphic rocks are formed from igneous, sedimentary and older metamorphic rocks that are introduced to extreme temperature and pressure. Because of the extreme temperature and pressure, rocks go through a significant chemical or physical change, turing them into metamorphic rocks.

Igneous rocks change to Metamorphic rocks through heat and pressure. Igneous rocks change to sedimentary rocks through weathering and erosion until the igneous rock is sediments. The sediments then compact to form sedimentary rocks.
Yes it can form an igneous rocks as because of pressure it may melt and form into igneous rocks.
Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.
By high pressure and temperature
heat and pressure.
The reason Igneous rocks are called primary or parent rocks are first, because they are made naturally by cooling lava. Second because Igneous rock can make Metamorphic or Sedimentary rock. This change or "parenting " can happen when Igneous rocks are broken down into sediments to create Sedimentary rocks, or when it is under high pressure and temperature to create Metamorphic rocks.
Yes, both sedimentary and igneous rock can be metamorphosed by heat and pressure.
igneous rocks
Igneous or sedimentary rocks that have been transformed by heat or pressure are known as metamorphic rocks.
Increased temperature and/or pressure.
