Sorry I don't know♀
Answer:
1) Intrusive igneous rocks that form at depth within the crust are termed plutonic (or abyssal) rocks and are usually coarse-grained. Intrusive igneous rocks that form near the surface are termed subvolcanic or hypabyssal rocks and they are usually much finer-grained, often resembling volcanic rock.
2) Another name for the core is desk due to the presence of nickel and iron.
3) Extrusive igneous rock, also known as volcanic rock, is formed by the cooling of molten magma on the earth's surface. The magma, which is brought to the surface through fissures or volcanic eruptions, rapidly solidifies.
4) Rocks contain carbon and fossils that give us important insights into the past.
5) These rocks are changed when heat or pressure alters the existing rock's physical or chemical make up. One ways rocks may change during metamorphism is by rearrangement of their mineral crystals. When heat and pressure change the environment of a rock, the crystals may respond by rearranging their structure.
