PHYS203 NJIT - Exam 1 UPDATED Actual
Exam Questions and CORRECT Answers
What is Oceanography? - CORRECT ANSWER✔✔- Study of earth's hydrosphere
What is Meteorology? - CORRECT ANSWER✔✔- study of earth's atmosphere
What is Biology? - CORRECT ANSWER✔✔- study of earth's biosphere
What is astronomy? - CORRECT ANSWER✔✔- study of earth's surroundings, primarily sun
and moon
What is geology? - CORRECT ANSWER✔✔- study of earth's geosphere
what spheres form planet earth? - CORRECT ANSWER✔✔- geosphere, hydrosphere,
biosphere, atmosphere
what is a system? - CORRECT ANSWER✔✔- collection of seemingly separate parts that are
actually interrelated to form a common whole
Examples of systems - CORRECT ANSWER✔✔- Nervous system = spinal cord, brain and
nerves
cardiovascular system = heart, arteries, veins, and capillaries
solar system = sun, planets and moons
what is an open system? - CORRECT ANSWER✔✔- system that exchanges both matter and
energy with its surrounding
what is a closed system? - CORRECT ANSWER✔✔- system that exchanges energy with its
surroundings but not matter
,what is an isolated system? - CORRECT ANSWER✔✔- system that does not exchange
matter and does not exchange energy with its surroundings
For all intents and purposes, what type of system is earth? - CORRECT ANSWER✔✔-
closed
In the strictest sense, what type of system is earth? - CORRECT ANSWER✔✔- open
What is earths internal energy source? - CORRECT ANSWER✔✔- geothermal energy
What is earths external energy source? - CORRECT ANSWER✔✔- the sun
Which spheres does the sun feed/drive? - CORRECT ANSWER✔✔- hydrosphere and the
atmosphere
Which sphere does the geothermal energy feed/drive? - CORRECT ANSWER✔✔-
geosphere
which type of energy feeds the biosphere? - CORRECT ANSWER✔✔- mostly fed by or
driven by the Sun, but remarkably a small part of the biosphere is driven by the geothermal
energy
Which system is impossible? - CORRECT ANSWER✔✔- one that exchanges matter without
exchanging energy
What happens once every 100 million years? - CORRECT ANSWER✔✔- rock falls from
space and causes catastrophe
how often does rock falls from space and causes catastrophe? - CORRECT ANSWER✔✔-
once every 100 million years
what is a sphere? - CORRECT ANSWER✔✔- geometrical shape with an equatorial radius
and a polar radius that are equal to each other
, example of meteorological processes? - CORRECT ANSWER✔✔- wind, rain, snow
why is earth not considered a sphere? - CORRECT ANSWER✔✔- b/c it rotates
what is an oblate spheroid - CORRECT ANSWER✔✔- has an equatorial radius that is larger
than its polar radius. (Its polar radius is smaller than its equatorial radius.)
what is a prolate spheroid - CORRECT ANSWER✔✔- has an equatorial radius that is
smaller than its polar radius. (Its polar radius is larger than its equatorial radius.)
What does the earths rotational axis cause the equator to do - CORRECT ANSWER✔✔- This
causes a centrifugal force that causes the Earth's equator to bugle outward
what is the true shape of the earth - CORRECT ANSWER✔✔- oblate spheroid
what is the true shape of every planet, moon, and star in the universe - CORRECT
ANSWER✔✔- oblate spheroid
From where (equator or poles) are you the closest to the center of the earth? - CORRECT
ANSWER✔✔- either pole
From where (equator or poles) are you the furthest from the center of the earth? - CORRECT
ANSWER✔✔- equator
as an excellent approximation for most intents and purposes since the centrifugal force is
weak, what is the shape of the earth? - CORRECT ANSWER✔✔- sphere
What is a great circle? - CORRECT ANSWER✔✔- The intersection of a sphere and a plane
that cuts the center of the sphere. (great circle is the largest possible circle that you can draw
on a sphere. The radius of a great circle is equal to the radius of the entire sphere)
