PHYS 203 Exam 1 Georgiou Latest Update
atmosphere - ANSWER air, weather
hydrosphere - ANSWER water, ice
biosphere - ANSWER plants, animals
geosphere - ANSWER land, rocks
exosphere - ANSWER sun, space
the earth system interacts with the exosphere
inductive reasoning - ANSWER drawing general conclusions from specific
observations
deductive reasoning - ANSWER drawing specific
conclusions based upon
general principles
why is it colder in winter and warmer in summer? - ANSWER Seasonal
temperature contrasts are due to the tilt of Earth's axis and angle of Sun's
rays. Tilt = 23.5 degrees
summer in northern hemisphere - ANSWER Sun is directly overhead
Tropic of Cancer
winter in northern hemisphere - ANSWER Sun is directly overhead at
Tropic of Capricorn
granite is composed of: - ANSWER feldspar, quartz, mica, amphibole
, all minerals are: - ANSWER (1) combination of elements
(2) charge neutral.
(3) Naturally Occuring (4) Inorganic
(5) Periodic in structure
ionic bonds - ANSWER Weak, balance of negative and positive charges of
different ions (NaCl - Halite or rock salt -- Na donates electron to Cl)
covalent bonds - ANSWER Strong, sharing of electrons between elements
to achieve a stable atomic structure.
Minerals formed with covalent bonds are stronger and more resistant to
destructive forces at Earth's surface
silicates - ANSWER form more resistant rocks than most other mineral
groups
Neptunism - ANSWER Rocks formed in a global ocean when material
sank to ocean floor or was precipitated from
chemical reactions (Example: Biochemical
rocks)
Plutonism - ANSWER Heat from Earth's interior melted rocks or caused
them to fuse together (Example: large grain Granite, small grain Basalt)
rock cycle - ANSWER A series of processes on the surface and inside
Earth that slowly changes rocks from one kind to another.
melting > crystallization > weathering > lithification > metamorphism >
melting > ...
Earth's interior can be divided into 3 major compositional layers: -
ANSWER crust, mantle, core
crust - ANSWER Earth's outermost layer. Composed of lighter elements
mantle - ANSWER Made of oxygen, silicon, magnesium.
Parts: lithosphere (rigid outer layer, tectonic plates) and asthenosphere
(plastic slowly flowing layer)
