Igneous rock forms when molten minerals cool from a liquid into a solid. Metamorphics forms deep under earth's crust where it's really hot.

Heat and pressure changes the rock's properties, eventually turning it into an metamorphic rock.

What is the major difference between igneous and metamorphic rocks?

igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).


Can metamorphic rocks form form igneous but not from sedimentary rocks?

Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.


What are the three types of rocks involved in the rock cycle?

The three types of rocks involved in the rock cycle are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form from the solidification of molten magma, sedimentary rocks form from the deposition and lithification of sediments, and metamorphic rocks form from pre-existing rocks that are subjected to high heat and pressure.


How do igneous rocks form into metamorphic and sedimentary rocks?

Igneous rocks can form metamorphic rocks by being subjected to high heat and pressure, causing recrystallization of minerals. Igneous rocks can also weather and erode to form sediment, which can then be deposited, compacted, and cemented to form sedimentary rocks.


How would you know the difference between igneous and sedimentary and metamorphic rock?

Igneous rocks form from cooling and solidification of magma or lava, sedimentary rocks form from the accumulation and cementation of sediment, and metamorphic rocks form from the alteration of existing rock through heat and pressure. By examining the texture, mineral composition, and sedimentary structures present in a rock sample, geologists can determine whether it is igneous, sedimentary, or metamorphic.

What and the difference between igneous and metamorphic rocks?

Igneous rocks are formed when rocks reach the melting point becoming magma, then the magma starts to cool and crystallizes to form igneous rocks. Metamorphic rocks are made when they come in contact with a mass of magma but does not melt providing the energy to drive chemical reactions that recrystallize minerals.
