GEOL 200 INTRODUCTORY PHYSICAL
GEOLOGY COMPLETE STUDY GUIDE WITH
SOLVED QUESTIONS
◉ abundant elements of Earth's Mantle.
Answer: oxygen, magnesium, silicon, iron
◉ 3 rock types.
Answer: igneous, sedimentary, metamorphic
◉ covalent bond.
Answer: when two atoms share electrons
◉ Ionic Bond.
Answer: forms because of the attraction of two oppositely charged
ions such as when one atom loans one or more electrons
◉ Metallic bond.
Answer: electrons shared widely by many atoms and holds the
material together in a non rigid way
◉ Intermolecular Force.
, Answer: several types of weak bonds can attract a molecule (a
combo of atoms) to another molecule
◉ Curie Temperature.
Answer: temperature at which certain magnetic materials undergo a
sharp change in their magnetic properties
◉ Paleomagnetism.
Answer: The record of past changes in earth's magnetic field, as
recorded in in rocks and other materials. It's strong enough to orient
magnetism in certain materials, especially in iron rich mineral
magnetite, in the direction of the prevailing magnetic field.
Preserved in volcanic rocks, intrusive rocks, and some sedimentary
rocks
◉ Magnetic North.
Answer: Earths magnetic field flows from south to north causing the
magnetic ends of a compass needle to point toward the north. (this
orientation is called normal polarity)
◉ Rock Magnetism.
Answer: A few iron bearing minerals naturally magnetic.
◉ Plate Tectonics.
