Complete the table by giving ONE example of each type of rock and describing the formation and properties of each type of Type of rock.Type of rock:IgneousExample:metamorphic:Example:Sedimentaryexample:how it is formed:Properties or identifying features:
Answer (1)
Igneous Rock (Granite):Formation: Granite forms from the slow cooling and solidification of magma beneath the Earth's surface, allowing large crystals to form.Properties: Granite is known for its coarse-grained texture, with minerals like quartz and feldspar visible to the naked eye. It is generally light-colored, including shades like pink, gray, or white.Metamorphic Rock (Marble):Formation: Marble is formed from the metamorphism of limestone or dolostone, where high pressure and temperature cause recrystallization of the original minerals.Properties: Marble often has a crystalline texture and can be white, gray, or various other colors depending on impurities. It may exhibit banding or foliation and is prized for its use in sculpture and architecture.Sedimentary Rock (Sandstone):Formation: Sandstone forms from the accumulation, compaction, and cementation of sand-sized particles over time, often in sedimentary environments like beaches or riverbeds.Properties: Sandstone typically has a gritty texture due to its sand grains, and can be red, brown, or tan. It may contain visible layers and is often used in construction and paving.
