Chapter 1 Introduction to Earth Science © 2015 Pearson Education, Inc. In the outset God created the heaven and the cosmos-people. Genesis 1:1 © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. God and affection • In Christian Theology: An Introduction, 2001, Alister E. McGrath says: God, in other articulation, is to be seen as the Primary Cause, and multitudinous agencies after a whilein the cosmos-people as the associated secondary causes. • The forces in affection (or, we may advert to the Laws of Nature) are uprightly named Secondary Cause(s). They owe their existence to God’s supported force. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. Three Meanings of the Word Science • The attainments base – Facts – Questions – Hypotheses – Theories • What is a supposition? Distinguish hypothesis from supposition. • The philosophical method • The philosophical establishment © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc.

Surely there is a disposition for the silver, and a assign for gold where they superior it. 2 Job 28:1 © 2015 Pearson Education, Inc. Chapter 2 Matter and Minerals © 2015 Pearson Education, Inc. MINERALS © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. Requirements for a Substance to be a Mineral • Must be Naturally happenring (must happen in affection; synthetic rubies are enclosing) • Must be Inorganic (not made of radical compounds) • Must be Crystalline (accept a crystal building – ordered dress of rudiment motes) • Must be Solid (minerals are not gases and liquids; ice fits but insinuate does not) • Must accept Definite visible properties and Definite chemical composition. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. Elements • Each component is secure of motes all of which accept the same distinctive chemical properties. • Atoms are the last units of subject that prove chemical properties, forming chemical compounds. • Atoms are marked by a kernel after a while protons and neutrons, concealed by orbiting electrons. Normally, protons balance electrons. The enumerate of electrons determines the chemical reactivity of an mote. The moteic enumerate of an component is the enumerate of protons in each kernel. • Atoms after a while past than 82 protons or varying enumerates of neutrons (named isotopes) accept inherently impermanent nuclei, and undergo radioactive declension, releasing firm particles and energetic rays. • Elements couple in chemical compounds via their motes sharing or transferring electrons, forming covalent and ionic bonds, respectively. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. How do we identify inanimates? – 1 • By falsification: a red inanimate is most slight not gold (which has a glacial gold falsification) or biotite (which has a sombre falsification). Impurities effect huge falsification variety; hereafter, falsification is not always a amiable way to identify a inanimate. • By radiance: the radiance of a inanimate delineates how glacial it looks subordinate light (silver has a vocal radiance while pure quartz has a limpid radiance). Options – vocal, submetallic, glabrous or limpid, pearly, silky, resinous, sad. • By streak falsification (or powder falsification): What falsification is the streak when a inanimate is rubbed on an unglazed porcelain platter? • By allureousness: How allureous is the inanimate? (The Mohs stoicism layer uses enumerates to delineate allureousness.) © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. How do we identify inanimates? – 2 • By crystal form: angles the crystal faces construct after a while each other; these desuperior crystal pattern and moteic symmetry. Crystals may be detailed, out-of-sorts formed, and complicated by impurities. A past unconcealed sign of “crystal form” is crystal form or “habit.”36 • By cleavage: whether, and in what habit, the inanimate breaks concurrently diluted inner bonds, producing one or past planar surfaces at convinced angles to one another.38 - Table • By fracture: inanimates not proveing cleavage will fracture. Types – riotous, conchoidal (level curved surfaces), splinters, fibers. • By local gravity: blindness (ρ ) referring-to to insinuate. Density ρ is mass/volume. Au - 20. PbS – 7.5. Most rocks – betwixt 2 and 3. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. Silicates Igneous inanimates. About 600 known. Make up 95% of lithosphere and preferable foam.
