Shape of Particles Angular Sub-roundedWell-rounded
Angular clasts Rounded clasts Clastic rocks: Sedimentary Rocks
Non-clastic Sedimentary Rocks Fine particles Layered
Conglomerates have rounded clasts Breccias have angular clasts Clast refers to the fragments of rocks. Angular clasts did not erode far from where the rock formed.
Arkose # 11 Arkose is a raw, coarse-grained sandstone, sandstone Clastic sedimentary rock
Gypsum # 12 Rock gypsum is an evaporite rock that forms as shallow sea basins or salt lakes Chemical sedimentary rock
Sandstone # 13 Sandstone rocks are sedimentary rocks made from small grains of the minerals quartz and feldspar. Clastic sedimentary rock
Shale # 14 Shale forms from the compaction of silt and clay that we commonly call "mud". Shale is best for fossil collection. Clastic sedimentary rock
Limestone # 15 Limestone form organically from shells and corals. Biologic sedimentary rock
Conglomerate # 16 A conglomerate is a rock consisting of individual clasts within a finer-grained matrix that have become cemented together.clastsmatrix Clastic sedimentary rock
Clastic sedimentary rock Foliated metamorphic rock Layered due to compaction Foliation Due to heat and pressure 10. What is the difference between layer and foliate or band?
Slate # 24 Slate is the lowest grade of metamorphic rock. Parent rock is the sedimentary rock shale.
Schist # 23 Schist is formed by regional metamorphism. Slightly Foliated rock.
Gneiss # 25 Gneiss ("nice") is a rock of great variety with large mineral grains arranged in wide bands. cgneiss.htm Forms deep beneath the ground or regional metamorphism. Foliated rock.
Amphibolite # 21 is a non-foliated metamorphic rock that forms through recrystallization under conditions of high viscosity and directed pressure. Contact metamorphism
Marble #22 Marble is a non-foliated metamorphic rock that is produced from the metamorphism of limestone. It is composed primarily of calcium carbonate.
Anthracite # 26 Metamorphic Rock Highest Quality of Coal Known as "Hard Coal“ s+Portfolio Non-Foliated rock.
Sedimentary and Metamorphic Rocks Eric Angat Teacher.
Sedimentary rocks. Conglomerate- clastic Made of rock pieces and pebbles that are rounded in shape.
Sedimentary Rocks Types and Classification. Detritial or Clastic Derived from the weathering of pre-existing rocks, which have been transported and deposited.
Rocks & Minerals. Minerals are the ingredients of rocks like ingredients make up a cake.
Classifying Rocks Igneous rocks are classified according to their origin, texture, and mineral composition. Origin Did it harden inside the earth or.
Std 3c. Know how to explain the properties of rocks based on the physical and chemical conditions in which they formed, including plate tectonic processes.

Sedimentary Rocks After completing this section, students will identify sedimentary rocks and explain how they are formed (Standard PI – 024)
The rock cycle illustrates the process that creates and changes rocks. The rock cycle shows the three types of rock- igneous, metamorphic, and sedimentary-
Unit 7 Rocks Rocks. 1.What are rocks?1. Rocks are a mixture of minerals, rock fragments, volcanic glass, organic matter, or other natural material. 2.
A rock is a naturally occurring solid mixture of one or more minerals, or organic matter Rocks are classified by how they are formed, their composition,
ROCK TYPES IGNEOUSMETAMORPHICSEDIMENTARY. What is a Rock? Rocks are naturally occurring solid material made from one or more minerals. Rocks are classified.
Rock Cycle Magma- Molten rock below the surface of the Earth Lava- Molten rock above the Earth’s surface Crystallization- When magma cools and forms igneous.
R oc ks Chapter 3 Rocks Naturally occurring solid material made of one or more minerals Grouped into 3 main types, based on the way it was formed.
Meaning to change shape Changes with temperature and pressure, but remains solid Usually.
Topic 3B – Rocks and the Rock Cycle Ms Cooke Earth Science
To analyze and describe the types of rocks that appear on Earth.
Aim: How can we explain sedimentary rock formation?

Chapter 4. Classifying rocks Rocks are made up of two or minerals. About 20 minerals make up most of the earth’s rocks. When studying rocks, geologists.
METAMORPHIC ROCKS Form when heat and/or pressure change existing rock into a new rock through recrystallization Types of Metamorphism –Regional Metamorphism.
Rocks Rock makes up the solid part of the earth. Rock is made from minerals or rock can be made of solid organic matter. Three classes of rock: Igneous,
Rocks & The Rock Cycle. Rocks vs Minerals ROCKS –SOLID MIXTURE OF MINERALS –MAY BE ORGANIC MINERALS –NATURALLY FORMED OF ELEMENTS OR COMPOUNDS –INORGANIC.

Rock cycle song Magma rises to form igneous rock It breaks down by weathering and erosion It washes away by wind and water, it washes away by.
Mr. Barr. When sediments are compacted and cemented together, this type of rock is formed. A. Sediments B. Sedimentary C. Metamorphic D. Igneous E. Magma.
BIG Idea ► Most rocks are formed from pre-existing rocks through external and internal geologic processes.
Extrusive Intrusive Granite is a coarse-grained, light colored, intrusive igneous rock that contains mainly quartz and feldspar minerals.
Chapter 4 - Rocks What can be learned by studying rocks… We can learn mo better about earth. So what is a rock??? Its a mixture of 1 or more minerals.
