GEOL 1001 QUESTIONS
AND ANSWERS 2026 -
2027
abundant elements of Earth's Crust - ANSWERS-oxygen, silicon,
aluminum, iron
abundant elements of Earth's Mantle - ANSWERS-oxygen, magnesium,
silicon, iron
3 rock types - ANSWERS-igneous, sedimentary, metamorphic
covalent bond - ANSWERS-when two atoms share electrons
Ionic Bond - ANSWERS-forms because of the attraction of two
oppositely charged ions such as when one atom loans one or more
electrons
Metallic bond - ANSWERS-electrons shared widely by many atoms and
holds the material together in a non rigid way

GEOL 1001 QUESTIONS
AND ANSWERS 2026 -
2027
Intermolecular Force - ANSWERS-several types of weak bonds can
attract a molecule (a combo of atoms) to another molecule
Curie Temperature - ANSWERS-temperature at which certain magnetic
materials undergo a sharp change in their magnetic properties
Paleomagnetism - ANSWERS-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 - ANSWERS-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 - ANSWERS-A few iron bearing minerals naturally
magnetic.
