Yes, if an igneous rock is heated, it will re-melt and turn back into magma.
Igneous rocks are formed by cooling magma.
Extrusive igneous rocks.
Igneous rocks are those that have solidified from lava or magma.
magma can make igneous rocks! igneous rocks are new rocks found in the earths crust formed around the plate boundaries. Magma from the mantle rises upwards towards the surface forming igneous rocks when it cools eg:-basalt ,granite
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
The metamorphic rock melts into magma then cools into igneous rock
Igneous rocks are formed by cooling magma.
The metamorphic rock melts into magma then cools into igneous rock
Your question as phrased is unclear. I will proceed to answer both interpretations I have of your question. Note: When magma crystallizes, it forms igneous rocks. 1) What is the change of state when magma forms from igneous rock? - Melting. Rocks are the solid state of matter and magma is the liquid state (although it can be a very viscous liquid). Changing something from solid to liquid is melting. 2) What is the change of state when magma crystallizes to form igneous rocks? - Solidification/Freezing. Magma becomes too cold to continue in a liquid state, it solidifies and crystallizes into solid igneous rocks: freezing.
By definition. A sedimentary rock is formed from sediments, chemical, organic, or clastic. A metamorphic rock has undergone a change in mineral alignment or mineral composition due to heat and/or pressure. An igneous rock forms from solidification of magma via cooling.
Magma is molten rock, and igneous rock is cooled magma.
Igneous Rocks - Rocks formed by crystallization from a melt (magma)
Extrusive igneous rocks.
Rocks formed from magma are igneous rocks. Extrusive igneous rocks form from lava at or near the surface. Intrusive rocks form from magma below the surface.
Igneous rock forms from the cooling of molten material called magma or lava.
Igneous rocks are those that have solidified from lava or magma.
Igneous rocks can change into metamorphic rocks from great heat and pressure as all other rocks can, melt into magma, the molten rock, and erode into sediment, which are rock fragments.
