Physical/ Petrological classification. In this video, you’ll learn how each type of rock forms, how to identify a rock’s type and how the processes of the rock cycle can move sediment and change one type of rock into another. Sedimentary rocks Sedimentary rocks are those rocks which are formed by the weathered sediments of pre existing rocks (igneous or metamorphic rocks). Introduction & Textures & Structures of Igneous Rocks Page 3 of 14 … Clastic sedimentary rocks are formed from the buildup of clatics: small pieces of fragmented rocks deposited as a result of mechanical weathering then lithified by compaction and cementation. DIGITAL PDF AND PRINT: Elementary and middle school teachers will download a no prep science packet. bettyd123. Some form during mountain-building by forces of others from the heat of igneous intrusions in regional metamorphism others from the heat of igneous intrusions in contact metamorphism. 3 years ago. Rock presentation heathergornall. 7. Vocabulary words and definitions ar. SEDIMENTARY ROCKS: • Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Metamorphic Rock is formed by heat and pressure from other rocks. enormous variety of rocks and their constituent minerals present in Earth’s crust, but all rock varieties are classified as one of three basic types: igneous, sedimentary and metamorphic. Igneous Rocks. These are rocks formed by the cooling of molten rock (magma). Geologists classify rocks into three main groups: igneous rock, sedimentary rock, and metamorphic rock. _____- after “weathering” occurs, the forces of running water, wind, or ice loosen and carry away fragments of rocks. Based upon the physical properties and alignment, rocks may be classified into following types: Stratified rocks are those which exhibit distinct layers which can be separated.

Metamorphic rocks are an important topic in geology. Because no two rocks are exactly alike, they are a lot of fun to collect. Depending on how the rock formed, rocks can be igneous, sedimentary, or metamorphic. IGNEOUS ROCKS SEDIMENTARY ROCKS METAMORPHIC ROCKS TYPES OF ROCKS-Forms when molten rock (magma/lava) cools and solidifies-Ignis means “ fire ”-Extrusive Igneous Rocks – Glassy and fine-grained texture-Intrusive Igneous Rocks - Crystallize below earth ’ s surface-Forms when sediments of rocks undergo lithification process-Sediments is produced by weathering and erosion. ; The scientific study of rocks is called petrology. Conglomerate, sandstone, limestone, chalk, calcite, and dolomite are example of sedimentary rocks. Types Of Rocks! They will also examine two versions of the rock cycle and label the parts. 8. Sills usually are fed by dikes, but these may not be exposed in the field. Igneous rocks. Types of Rock Kristin Voolstra. These basic types of rock relate to the manner in which the rocks were formed. The first type of rock on this list are the igneous type of rocks. Metamorphic rocks are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which the original rock was formed. Petrology is the science of rocks. Some types of metamorphic rocks, such as quartzite and marble, which can form whether there is directed-pressure or not, do not typically exhibit foliation because their minerals (quartz and calcite respectively) do not tend to show alignment (see Figure \(\PageIndex{8}\)). Sedimentary Rock They are out particles sand, pebbles, and other They made of of sand, shells, pebbles and other This type of rock is particles madeofout ofshells, sand, shells, pebbles and material.
