Rocks-Connor A.

Stack #127636

QuestionAnswer
Basaltic describes dense, dark-colored igneous rock formed from magma rich in magnesium and iron and poor in silica
Cementation sedimentary rock-forming process in which sediment grains are held together by natural cements that are produced when water moves through rock and soil
Compaction process that forms sedimentary rocks when layers of sediments are compressed by the weight of the layers above them
Extrusive describes fine-grained igneous rock that forms when magma cools quickly at or near earths surface.
Foliated describes metamorphic rock, such as slate and gneiss, whose mineral grains line up in parallel layers.
Granitic describes generally light-colored, silica-rich igneous rock that is less dense than basaltic rock
Igneous rock rock formed when magma or lava cools and hardens.
Intrusive describes a type of igneous rock that generally contains large crystals and forms when magma cools slowly beneath Earth's surface.
Lava molten rock that flows from volcanoes onto Earth's surface
Metamorphic rock forms when heat, pressure, or fluids act on igneous, sedmentary, or other metamorphic rock to change its form and composition, or both
Nonfoliated describes metamorphic rock, such as quartzite or marble, whose mineral grains grow and rearrange but generally do not form layers.
Rock mixture of one or more minerals, rock fragments, volcanic glass, organic matter, or other natural materials; can be igneous, metamorphic, or sedimentary.
Rock cycle model that describes how rocks slowly change from one form to another through time.
Sedimentary rock forms when sediments are compacted and cemented together or when minerals form from solutions.
Sediment loose materials, such as rock fragments, mineral grains, and the remains of once-living plants and animals, that have been moved by wind, water, ice, or gravity.
