ESC 1000 Exam 1- Study Guide
QUESTIONS & ANSWERS CORRECT
100%
What is the age of the Earth? - ANSWER4.6 billion years old
What are the four disciplines that make-up Earth Science? - ANSWERGeology,
Oceanography, Meteorology, and Astronomy.
What are the layers of the Earth based on composition? - ANSWERCrust, mantle,
and core
What controls the cooling rate of cooling of igneous rocks? - ANSWERIt depends on
the depth in the Earth. Places on the surface have fast cooling rates while places
inside the earth have slow cooling rates. The cooling rate determines the size, and
therefore the texture, of igneous rocks
Why do sedimentary rocks cover much of the Earth's surface but make-up so little of
the volume of total rocks on the planet? - ANSWERSedimentary rocks form on the
surface of the earth, so they make a large percentage of the surface rocks. Igneous
and metamorphic are created inside the earth so they're less common on the surface
How do ionic bonds differ from covalent bonds? - ANSWERIonic bonds= Electrons
are transferred
Covalent bonds= Electrons are shared
What are the layers of the Earth based on physical property? -
ANSWERLithosphere, upper mantle, asthenosphere, outer core, and inner core
What five characteristics must be met to consider a substance a mineral? -
ANSWERNaturally occurring, generally inorganic, solid substance, orderly crystalline
structure, and definite chemical composition
What is an isotope? - ANSWERVarieties of the same elements that have different
mass numbers; their nuclei contain the same number of protons but different
numbers of neutrons.
What do the atomic - ANSWER
What does halite presence tell us? - ANSWERThe mineral is table salt
What metamorphic settings did we discuss in class? - ANSWERContact
metamorphism and regional metamorphism
