Was there a resolution presented? Briefly discuss the resolution. Igneous Rock  Igneous Rocks ❏ Igneous rocks form from the cooling and hardening of molten magma. ❏ These rocks can form by slowly cooling beneath the surface or more quickly at the surface.  Igneous Rocks INTRUSIVE EXTRUSIVE Formed from MAGMA Where LAVA Rate of Cooling Size of Crystals Texture  Igneous Rocks INTRUSIVE EXTRUSIVE Inside the Formed from Surface of Earth Where the Earth Rate of Cooling Size of Crystals Texture  Igneous Rocks INTRUSIVE EXTRUSIVE Formed from Slowly Where Quickl Rate of Cooling y Size of Crystals Texture  Igneous Rocks INTRUSIVE EXTRUSIVE Formed from Large Where Small “Vesicular” Rate of Cooling Size of Crystals Texture  Igneous Rocks INTRUSIVE EXTRUSIVE Coarse Formed from Fine “Phaneritic” Where “Aphanitic” Rate of Cooling Size of Crystals Texture  Percent of Silica 0 45 60 100 MAFIC Intermediate FELSIC ➔ Dark in color ➔ Light in color Mg Fe Ca K Al Na Igneous Rocks Sedimentar y Rock Sedimentary Rocks ❏ Sedimentary rocks form by the compaction and cementing together of sediments. ❏ These rocks can be formed from erosion and weathering of other rocks. examples Sediment ➔ fragments of rock that have been broken down as a result of weathering.  Erosion Sedimentary Deposition Rocks Compaction Cementation  Sedimentary Erosion Rocks ➔ The removal and transportation of rock or soil. ➔ Erosion can move sediment through water, ice, or wind.  Sedimentary Deposition Rocks ➔ The geological process in which sediments, soil and rocks are added to a landform or landmass.  Sedimentary Compaction Rocks ➔ This happens when sediments are deeply buried, placing them under pressure because of the weight of overlying layers. ➔ This squashes the grains together more tightly.  Sedimentary CementationRocks ➔ Process where new minerals stick the grains together – just as cement (from a bag) binds sand grains in a bricklayer’s mortar. Characteristics of Sedimentary Rocks ❏ One of the most distinctive characteristics of sedimentary rocks is their layered or stratified structure. ❏ These layers, called strata, often contain valuable information about the Earth’s past environment Layered Structure ❏ Sedimentary rocks often contain visible particles or fragments of various sizes ❏ These particles are often sorted by size due to the selective action of water, wind, or ice during the deposition process. Visible Particles  ❏ composed of a wide range of materials, including mineral grains, organic matter, and even chemical precipitates. ❏ This diversity in composition is due to the different sources of sediments and the processes they undergo during formation.
