GEG 111 Exam 3 Questions With Correct
Answers
Geomorphology |- |CORRECT |ANSWER✔✔-The |study |of |Earth's |surface |landforms |- |their |origin, |
evolution, |form, |and |spatial |distribution
Layers |of |Earth's |Interior |- |CORRECT |ANSWER✔✔-Earth's |Core |(inner |and |outer)--> |Earth's |
mantle |(lower |and |upper)--> |Earth's |crust--> |Asthenosphere |and |Lithosphere
Earth's |Core |- |CORRECT |ANSWER✔✔-The |core |is |differentiated |into |an
inner |core |and |outer |core.
• |Earth's |outer |core |is |separated |from
the |mantle |by |a |transition |zone
known |as |the |Gutenberg
discontinuity.
Earth's |Crust |- |CORRECT |ANSWER✔✔-Outer |layer, |thickness |varies. |Made |up |of |8 |natural |
resources. |Continental |and |Oceanic: |continental |made |out |of |granite, |oceanic |made |out |of |
basalt
Asthenosphere |and |Lithosphere |- |CORRECT |ANSWER✔✔-The |interior |layers |of |core, |mantle,
and |crust |are |differentiated |by |chemical |composition.
• |The |outer |part |is |divided |into |the
lithosphere |(rigid |layer) |and |the
asthenosphere |(plastic |layer).
, Mineral |- |CORRECT |ANSWER✔✔-An |inorganic, |natural, |solid |compound |with |a |specific |
chemical |formula, |and |often |a |crystalline |structure. |Earth's |most |common |mineral |is |quartz |
SiO2.
Common |mineral |groups |- |CORRECT |ANSWER✔✔-Silicates, |Oxides, |Sulfides |& |Sulfates, |
Carbonates, |Halides.
Rock |- |CORRECT |ANSWER✔✔-A |collection |of |minerals |or |a |single |mineral |that |forms |a |mass. |
Examples |include |granite, |obsidian, |coal.
3 |basic |types |of |rock |- |CORRECT |ANSWER✔✔-1) |Igneous |(formed |from |molten |material) |
2)Sedimentary |(formed |from |compaction |or |chemical |processes).
3) |Metamorphic |(altered |by |heat |and |pressure)
Igneous |Processes |- |CORRECT |ANSWER✔✔-• |Igneous |rocks |form |from |magma, |which |is |
molten |rock |beneath |Earth's |surface.
• |When |magma |emerges |at |the |surface, |it |is |lava, |although |it |retains |its |molten
characteristics.
• |Igneous |rocks |make |up |about |90% |of |Earth's |crust, |although |sedimentary |rocks, |soil, |or |
oceans |frequently |cover |them.
Sedimentary |Processes |- |CORRECT |ANSWER✔✔-Sedimentary |rocks |are |formed |from |the |
compaction |and |cementation |of |small |particles |deposited |by |the |wind |or |water
• |The |small |particles |are |known |as |clasts |(grains |or |fragments)
• |The |particles |may |come |from:The |weathering |and |erosion |of |existing |rock |(e.g. |sandstone), |
the |accumulation |of |shells |on |the |ocean |floor |(e.g. |limestone), |the |accumulation |of |organic
matter |from |ancient |plants |(e.g.
coal), |or |the |precipitation |of |minerals
from |solution |(e.g. |limestone)
