Cooling to a solid.
magma
Metamorphic rocks become igneous rocks by melting from heat and pressure, remnants of which may cool from melt (magma) and become components of igneous rock.
Igneous rocks are formed by cooling magma.
lava and/or magma cools and forms igneous rocks. igneous rocks go through weather and erosion which forms sediments. these sediments are collected and compacted. this causes sedimentary rocks. the sedimentary rocks go through weather and erosion as well as being exposed to heat and pressure. this causes metamorphic rocks. metamorphic rocks go through heat and pressure and then they melt and become lava or magma again. this is called the rock cycle.
Cooled and solidified magma that rests below the surface becomes intrusive igneous rock. When magma is erupted onto the surface, then cools and solidifies, it becomes extrusive igneous rock. The major rock classification for cooled magma or lava would be IGNEOUS.
Magma is molten rock, and igneous rock is cooled magma.
Well, Igneous Rocks are formed from Magma and the bones of an animal or a plant wouldn't have the time to become a fossil
Igneous Rocks - Rocks formed by crystallization from a melt (magma)
Igneous rocks are formed when magma solidifies, or becomes solid. Rocks become magma when they undergo extreme heat.
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.
