The three types are:Igneous rocksform from cooling magma or lava.Sedimentary rocksform from the bonding of rockfragments such as sand, silt, or clay; from organicmaterials; and from chemicals dissolved in water.Metamorphic rocksform when other rocks arechanged by heat and pressure.In theRock ClassificationGizmo™, you will get to explore these three types of rocks. Thinkabout how each type of rock is formed.1.Fossilsare the remains of ancient plants and animals. Which type of rock do you think ismost likely to contain fossils? _________________________________________________2.Foliationoccurs when minerals are flattened by heat and pressure. This results in a layeredor banded texture. Which type of rock do you think is foliated? _______________________3.Air pockets can form in rapidly cooling magma or lava. In which type of rock would youexpect air pockets? _________________________________________________________
