Syenites are on the border between the QAP and the APF triangles. Mineral and Rock Vocabulary. Rock. Rock is a solid mixture of crystals of one or more minerals. Rocks are categorized into 3 types on how they are made. Each rock in each category is classified (named) by its TEXTURE and COMPOSITION. Granite, Basalt, Obsidian, Pumice and many others . Igneous Rocks are records of the thermal history of Earth. Most common of all rocks is Granite: . Granite . is a light-colored . igneous rock.  with grains large enough to be visible with the unaided eye.  It forms from the slow crystallization of magma below Earth’s surface.  Granite is composed mainly of quartz and  feldspar with minor amounts of mica, amphiboles and other minerals.   This mineral composition usually gives granite a red, pink, gray or white color with dark mineral grains visible throughout the rock. A rock is a naturally occurring . solid. mixture composed of . minerals. , . smaller rock fragments. , . organic. . material. , or . glass. . The individual particles in a rock are known as . grains. Types of Rocks. Rock: an aggregate of one or more minerals. Igneous Rocks: crystallize from a magma. Sedimentary Rocks. Clastic: formed by the erosion of pre-existing rocks. Chemical/Biochemical: precipitated from chemical reactions. 3 Types of Rocks. There are 3 different types of rocks;. Igneous. Sedimentary. Metamorphic. Igneous Rock . . Igneous rocks are formed by magma and lava as it cools. Igneous rocks form in two different ways. . Rocks are classified by how they are formed, their composition, and texture. Rocks change over time through the rock cycle. TYPES OF ROCKS. ROCKS ARE DIVIDED INTO THREE GROUPS BASED ON HOW THE ROCKS . a. metamorphic rock. . b. sedimentary rock. . c. igneous rock. d. sediment. . #1. Which of the following processes is NOT part of the rock cycle?. a. solidification. . b. chiseling. c. erosion. d. metamorphism. 2. Major Rock Groups. Igneous. Formed from . molten rock (magma/lava) that has cooled. Literally means “from fire”. 1. Extrusive . igneous rock is formed from lava (on earth’s surface) and tends to solidify quickly. Metamorphic. Rock. What is it made up of?. Sand, clay, silt, organic matter (fossils). How is it formed (process)?. Weathering. (wind, flowing water, ice, living organisms) create sediment. Erosion. CLASSIFICATION OF ROCKS:. ON THE BASIS OF MODE OF FORMATION ROCKS ARE CLASSIFIED INTO THREE CATEGORIES:. 1 IGNEOUS ROCKS. 2 SEDIMENTARY ROCKS. 3 METAMORPHIC ROCKS.  . ROCKS. IGNEOUS ROCKS:.  .
