Elements in Earth ScienceEach element is made of atoms that are the same Each atom is made of protons, neutrons, and electrons
Most Common Elements in Earth ScienceOxygen O Silicon Si Aluminum Al Iron Fe Calcium Ca Sodium Na Potassium K Magnesium Mg Titanium Ti Hydrogen H
In general … simpler elements are more commonIn general … the more familiar an element, the more abundant
Minerals Is an element or compound found naturally in rocks and soils.There are more than 3500 named minerals. New minerals are being found every year.
Characteristics of MineralsAll are solids Form naturally Never part of living things Definite chemical makeup Definite atomic pattern
Slow cooling minerals form large crystalsFast cooling minerals form small crystals
Rocks Made up of one or more minerals3 types: Igneous, Sedimentary, Metamorphic
Igneous Fire formed Cools and hardens from magma Magma is in the earthLava is on the earth
2 types of Igneous Intrusive – cools inside Earth Cools slowlyExtrusive – cools outside Earth Cools quickly
Intrusive Granite – most common, “mountain guts”Diorite – iron and magnesium Gabbro – dark, large crystals Peridotite – green, most of upper crust
Extrusive Basalt – common, hard, darkAndesite – began cooling in crust finished on surface large/small crystals Rhyolite – cooled slowly then fast Pumice – light, spongy look Obsidian – volcanic glass, cools fast
Sedimentary Layers of particles that are moved from one place to another. 3 types: Clastic, Chemical, Organic
Clastic Most common Made of other rocksParticles accumulate and harden Weathering is an active process
2 Processes cause clastics to hardenWeight of upper layers squeeze out liquids Minerals dissolved in ground water act as cement
Conglomerate – pebble pieces, roundedBreccia – boulder pieces, sharp
Sandstone – sandsized quartz, variety of colorsShale – most common, mud, clay, silts
Chemical Limestone – 50% calcite from seashellsCoquina – large pieces of shell Chalk – microscopic pieces of shell
Halite – hard, created by evaporationGypsum – soft, created by evaporation Chert – hard, created by heat
Organic Coal – black, coarse, decayed plant life
Special Features of Sedimentary RocksLayering (bedding) Fossils Geode (minerals in a hole or cavity) Concretions (minerals form around a grain or fossil)
Metamorphic Created by 1 of 2 processesRegional process – most common, heat and pressure over large area Contact – heat and pressure next to magma chambers 2 types: Foliated, Nonfoliated
Foliated “layered” rocks Slate – made from shaleGneiss – made from granite
Nonfoliated No ‘layers’ Marble – made from limestoneQuartzite – made from quartz
Geology Part II The Rock Cycle Rocks: Geologic Profiles Geologic Time
The rock cycle illustrates the process that creates and changes rocks. The rock cycle shows the three types of rock- igneous, metamorphic, and sedimentary-
Rocks & The Rock Cycle.
Rocks The solid mineral material forming part of the surface of the earth and other planets.
Chapter 4 - Rocks What can be learned by studying rocks…
Uniformitarianism: 1795 – James Hutton “the present is the key to the past” we can learn about Earth’s history by studying present processes.
How are Rocks classified
Rocks & The Rock Cycle. Notes The Rock Cycle Notes - Advanced Write the definition of a rock: Rocks - A solid, naturally occurring mineral or mineral-like.
Types of Rocks. 3 Basic Types Sedimentary Igneous Metamorphic.
Classifying Rocks Igneous rocks are classified according to their origin, texture, and mineral composition. Origin Did it harden inside the earth or.
Types of Rocks Chapter 31 There are three main types of rocks:
The Rock Cycle
Schist Pumice Rocks pg 84 Pegmatite Gneiss Scoria coquina.
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,
Igneous Rock Forms when molten rock (magma/lava) cools and hardens
Chapter 2 Review – ROCKS Rocks #1Rocks #2Knowledge.
Rocks Igneous Metamorphic Sedimentary. What is a Rock? A rock is composed of minerals Can be made of organic material Solid material that forms Earth’s.
Classifying Rocks Geologists observe: Mineral composition Color
Earth Science Rocks!!. How Igneous Rock Is Formed They are formed by the crystallization of magma or lava Igneous rocks may form deep inside the Earth.
What are rocks made of? Minerals are not made by people; they are … …naturally occurring substances.
*observe color and texture to determine mineral composition Texture- look & feel of rock’s surface Grains- particles of minerals or other rocks.
Classification based upon formation
Rocks ROCKS Chapter 3.
Rocks and the Rock Cycle:
Classification of Rocks. 1. How do the crystals or minerals form in a rock? 2. Why do some rocks have layers? 3. Why do some rocks have rounded particles.
Rocks & Minerals. Minerals are the ingredients of rocks like ingredients make up a cake.
Geology Notes Part 1 The Rock Cycle. What is a rock? A rock is a mixture of such minerals, rock fragments, volcanic glass, organic matter, or other natural.
Rocks and the Rock Cycle
Rocks Rocks are made of minerals.
Mineral & Rock Review Chapters 3 & 4. Minerals A naturally occurring, inorganic solid with crystal structure and a definite chemical composition Families.
Petrology All about rocks!. Essential Questions What is the rock cycle? What are the three types of rocks?
Sedimentary, Igneous, and Metamorphic
Unit 3 Rocks, Soil, Erosion and Mass Movements
DO NOW Rock Cycle and Types of Rocks
Igneous rocks Crystallize from a molten rock: magma
Mr. Skirbst Earth Science Topic 23
Rock Classification. 3 types of Rocks 1.Igneous Intrusive - granite Extrusive - basalt 2.Sedimentary Clastic - conglomerate Chemical – rock salt Organic.
Minerals and Rocks. Properties of Minerals Luster Streak Hardness Cleavage.
Mrs. Negrito 6th Grade Science Chapter 16 Section 1 & 2
Igneous Rocks From lava or magma Can be either extrusive (formed on Earth’s surface, from lava) Or intrusive (formed inside of the Earth’s surface, from.

ROCK IDENTIFICATION LAB. What type of rock is this? Where or how is it formed?
ROCKS By Gina Wike ROCKS A rock is defined as a mixture of minerals, mineraloids, glass, or organic matter.
Types of Rocks Test Mr. Barr.
By Paige Black A rock is a naturally occurring solid mixture of one or more minerals, or organic matter. Rocks are classified.
