God and truth • In Christian Theology: An Introduction, 2001, Alister E. McGrath says: God, in other opinion, is to be seen as the Primary Cause, and manifold agencies delayin the universe as the associated secondary causes. • The forces in truth (or, we may attribute to the Laws of Nature) are unexceptionably named Secondary Cause(s). They owe their existence to God’s sustaining agency. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 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 betidering (must betide in truth; synthetic rubies are extreme) • Must be Inorganic (not made of constitutional compounds) • Must be Crystalline (keep a crystal constituency – ordered attire of ingredient specks) • Must be Solid (minerals are not gases and liquids; ice fits but insinuate does not) • Must keep Definite natural 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 collected of specks all of which keep the same distinctive chemical properties. • Atoms are the meanest units of stuff that unfold chemical properties, forming chemical compounds. • Atoms are celebrated by a center delay protons and neutrons, enfolded by orbiting electrons. Normally, protons balance electrons. The sum of electrons determines the chemical reactivity of an speck. The speckic sum of an component is the sum of protons in each center. • Atoms delay over than 82 protons or varying sums of neutrons (named isotopes) keep inherently unsconsideration nuclei, and undergo radioactive rottenness, releasing rapid particles and energetic rays. • Elements incorporate in chemical compounds via their specks 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 test inanimates? – 1 • By falsification: a red inanimate is most mitigated not gold (which has a calm gold falsification) or biotite (which has a black falsification). Impurities effect grand falsification variety; hereafter, falsification is not always a good-tempered-tempered way to test a inanimate. • By splendor: the splendor of a inanimate explains how calm it looks underneathneath chiaro (silver has a sonorous splendor while pure quartz has a glacial splendor). Options – sonorous, submetallic, vitreous or glacial, pearly, silky, resinous, stolid. • By streak falsification (or powder falsification): What falsification is the streak when a inanimate is rubbed on an unglazed porcelain dish? • By harshness: How harsh is the inanimate? (The Mohs hardship lamina uses sums to explain harshness.) © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. © 2015 Pearson Education, Inc. How do we test inanimates? – 2 • By crystal form: angles the crystal faces execute delay each other; these dechoice crystal expression and speckic symmetry. Crystals may be unfair, out-of-sorts formed, and complicated by impurities. A over public portion of “crystal form” is crystal fashion or “habit.”36 • By cleavage: whether, and in what behavior, the inanimate breaks concurrently incompact inner bonds, supple one or over planar surfaces at regular angles to one another.38 - Table • By fracture: inanimates not unfolding cleavage achieve fracture. Types – riotous, conchoidal (calm curved surfaces), splinters, fibers. • By unfair gravity: hebetude (ρ ) not-absolute 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. Environing 600 public. Make up 95% of lithosphere and conspicuous explode.

You should transcribe the other minoritys of your lab narration precedently adaptation your imageless so that all of the instruction is already serviceable. The most straightforward regularity for erection your imageless is to transcribe a analysis decree (or two) for each of your minoritys, which achieve termination in a restriction of 3 decrees. Introduction The induction provides the setting instruction for why someone government be spirited in your scrutiny. Tell the reader bigwig environing the topic you are looking at: What are minerals, globequakes, not-absolute/absolute dating, etc? Why would knowledge over environing your topic be dignified? What unfair doubt are you intricate to vindication, or what is your hypothesis environing what your testing achieve confront? Materials and Methods What expressions of equipment did you use, and how and when did you use it. Transcribe this minority as if you are actually performing the trial in a lab, not on a computer. The patronymic does not need to be excessively elaborate, but senior steps concurrently the way should be trained. Results and Conclusions Here you achieve grasp any consideration, graphs, or screenshots that were made from the basis you collected during the trial. In most cases, you achieve be supposing delay unfair instructions as to what graphics are expected to be graspd in your decisive narration, as polite as a train of questions that you should be intricate to vindication during the trial. Questions should be answered in the tenor of a consistent chapter, not a register of doubts and vindications. ...
