Igneous rocks can be transformed not made but i think you are asking what types of rocks are igneous rocks well any rock that had once been lava/molten is an igneous rock and lava/molten comes from volcano.You might want to search on Google-types of igneous rocks or how can igneous rocks be transformed. From Ayushi:)
Igneous rocks can be any color.Igneous rocks come in a variety of colors. However the main colors are white, black, gray, greenand pink.
Sedimentary, Igneous, and Metamorphic rocks are the 3 types of rocks.
An igneous rock could be of any size, from microscopic to miles in diameter.
no any type of rock can become any other or another form of itself.
Igneous rocks are one of three classifications of rocks. Igneous rocks are formed as a direct result of crystalline solids being formed by the cooling of magma. Sedimentary rocks are the result of pieces broken from chemical, clastic and organic rock. Metamorphic rocks can be any kind of rock and are formed when a rock goes through metamorphic changes, usually due to a buried rock coming in contact with unstable minerals.
Sedimentary rocks are formed when other rocks (igneous, metamorphic, or sedimentary) are weathered and eroded and their sediments are compacted and cemented together. Metamorphic rocks can be formed when heat and pressure is applied to any type of existing rock. Igneous rocks are formed when magma cools. The magma can be made up of melted rocks of any kind (sedimentary, igneous, or metamorphic). The cycle repeats itself all the time and all of the rocks can come from any other kind of rock.
no any type of rock can become any other or another form of itself.
Any rock created by the cooling of magma or molten material is classified as an igneous rock. These rocks can either be cooled in the earth or on the earths surface. Rocks cooled inside the earth are called intrusive igneous rocks, and have large crystals. Rocks cooled on the earth's surface are called extrusive igneous rocks. These rocks, due to faster cooling times, have very very tiny crystals.
Igneous rocks are rocks formed by magma. so the best place to find igneous rocks would be by volcanoes or where a volcano once erupted.
Some examples of igneous rocks not belonging to the three major families (basalt, granite, andesite) include obsidian, pumice, and tuff. These rocks form from unique cooling conditions or compositions, leading to textures and mineral content that differentiate them from the more common igneous rock types.
The black in igneous and metamorphic rocks could be any of numerous black minerals. Two that are commonly found are biotite mica and hornblende.
