Identifying Types of Igneous Rocks Quiz

Basalt is an igneous rock that is formed from the rapid cooling of lava.

Dunite is a type of igneous rock that primarily consists of the mineral olivine. It is formed from the mantle of the Earth and is considered part of the ultramafic rock family.

Granite is formed from the slow crystallization of magma deep beneath the Earth's surface, making it an igneous rock.

Peridotite is an igneous rock formed from the cooling and solidification of magma.

Rhyolite is an igneous rock formed from volcanic activity.

Andesite is a type of igneous rock formed from the solidification of volcanic lava on the surface of the Earth.

Diorite is a type of igneous rock formed from the cooling and solidification of magma or lava. It is composed mainly of plagioclase feldspar, biotite, hornblende, and pyroxene.

Gabbro is a type of igneous rock formed from the slow cooling of magma underground.

Peridotite is a type of igneous rock that is formed deep within the Earth's mantle through the process of magmatic differentiation.

Rhyolite is an igneous rock formed from the cooling and solidification of magma or lava.

Chert is a sedimentary rock primarily composed of microcrystalline or cryptocrystalline quartz.

Arkose is a type of sedimentary rock that is often associated with the deposition of sand in a river or sea environment, typically containing high amounts of feldspar.

Breccia is a type of sedimentary rock formed from angular fragments of rocks cemented together.

Chalk is a soft, white, porous sedimentary rock formed from the remains of microscopic marine organisms.

Chert is a type of sedimentary rock formed primarily of microcrystalline or cryptocrystalline quartz. It is commonly found in limestone deposits and is often associated with the remains of marine organisms.

Conglomerate rock is a type of sedimentary rock that forms from the compression and cementation of rounded pebbles and rocks. Therefore, when a conglomerate rock undergoes further compaction and cementation, it transforms into a sedimentary rock.

Limestone is a sedimentary rock formed from the remains of ancient marine organisms. Igneous rocks form from the cooling and solidification of magma or lava. Metamorphic rocks are formed through the alteration of pre-existing rock types. Volcanic rocks are igneous rocks formed from volcanic activity.

Quartz Sandstone is a type of sedimentary rock that is formed from the cementation of quartz grains. Sedimentary rocks are formed through the deposition and solidification of sediment.

Gypsum is a sedimentary rock that is commonly found in evaporite deposits.

Sandstone is a type of sedimentary rock formed from compressed sand.

Shale is a type of sedimentary rock formed from the compaction of clay and silt particles over time. It is characterized by its fine grains and ability to split into thin layers.

Siltstone is a type of sedimentary rock formed from compressed silt particles.

Greenstone is a type of rock that forms through the alteration of pre-existing rocks under high temperatures and pressures, making it a metamorphic rock.

Schist is a type of metamorphic rock that is characterized by its medium to coarse-grained texture and its well-developed foliation resulting from the parallel alignment of platy minerals like micas.

Phyllite is a type of metamorphic rock formed from the metamorphism of slate.

Quartzite is a metamorphic rock that is formed from sandstone under high pressure and heat.

Quartzite is a metamorphic rock formed from sandstone that undergoes metamorphism, a process of high heat and pressure.

Gneiss is a metamorphic rock formed through intense heat and pressure, unlike igneous rocks which form from the cooling of magma, and sedimentary rocks which are formed through sediment accumulation.

Marble is a metamorphic rock formed from limestone undergoing metamorphism, which is a process where heat and pressure alter the rock's mineralogy and texture.

Coal is formed from dead plant matter that has been compressed and heated over millions of years. This process mainly occurs in sedimentary environments, leading to coal being classified as a sedimentary rock.
