they are dark colored rocks that are rich in calcium,iron,and magnesium,poor in siliconmafic
it takes longer to cool,giving mineral crystals more time to grow(cooled quickly,underground)coarse grained
it cools quickly with little to no crystals.(cooled quickly,at surface)fine grained
magma pushes into surrounding rock below the earth's surface,cools slowly with larger crystal formationintrusive igneous rocks
forms when magma erupts onto the earth's surface(lava),cools quickly with very small or no crystal formed.extrusion igneous rocks
it is a dark colored volcanic glass that forms from the very rapid cooling of molten rock materialsobsidian
it cools quickly that no crystals do no formobsidian
it is formed by erosion and by lithification of sediments(sand,silt,clay)sedimentary rocks
they are deposited in layers,with the older ones on the bottomsediments
the layers become compacted and cemented togetherlithification
they are formed at or near the earth's surfacesedimentary rocks
no heat and no pressure involvedsedimentary rocks
it is the layers of rocksstrata
it is the process in which sedimentary rocks are arranged in layersstratification
it is made of fragments of rocks cemented together with calcite or quartzclastic
minerals crystallised out of solution to become rockschemical sedimentary
it is primarily composed of calcium carbohydratelimestone
it is the remains of plants and animalsorganic sedimentary
it forms from the accumulation and preservation of plan materials,usually in a swampcoal
it is formed by transformations of pre existing rocks(in the solid statemetamorphic rocks
