Prof. Leavitt, YES, I DO understand the basics of the
Earth System! You will never want to go back
to your radio DJ career after you see my mastery of the topics below:
ORIGINS
1. The Big Bang took place .
A. when the Earth
formed C. 4.6 billion
years years ago E. A & D
B. when the ocean
formed D. 15 billion
years years ago
2. The farther a given galaxy is away from us,
_________________.
A. the faster it is
moving away from us C. the
more stars it contains
B. the faster it is
moving toward us D. the
more lead and iron it contains
3. The layered structure of the inside of the Earth is
primarily the result of .
A. PDO C. melting
and gravity separation E.
the Big Bang
B. supernova D. the red shift F. gyres
___4. In our solar
system, Saturn belongs to a group of planets (the
"Jovian"/"Great Outer" group) with .
A. high density and
lots of Mg, Si, Fe, O C. low
density and lots of N, H, C
B. high density and
lots of N, H, C D.
low density and lots of Mg, Si, Fe, O
5. The reaction of
H+H to produce He releases tremendous energy inside our Sun and is known as
________.
A. chemical bonding C.
oxidation
B. hydrogen bonding D. nuclear fusion
6. The first nebulas that formed in the universe were
composed of only hydrogen and helium (Big Bang residue). Which of the following is evidence that the
nebula from which our solar
system formed was at least in part derived (formed) from the remnants of
earlier stars?
A. the Hubble
constant C. helium balloons
on your birthday
B. the red shift D. the carbon in your
pencil
7. Which of the following contains a story of epic
proportions, spanning great time and distances, about the origin of the matter
we see around us today?
A. Periodic Table of
elements C. Lord of the
Rings E. Star
Wars
B. the book “From
Here to Eternity” D. “Contact” by
Carl Sagan
8. The Earth’s
atmosphere and ocean were probably predominantly formed ______.
A. by photodissociation C.
by Earth capture of the solar wind E.
by photosynthesis
B. by outgassing of the Earth’s interior D.
during the Big Bang
THERMODYNAMICS,
9. The First Law of Thermodynamics states that .
A. gravity can hurt
your head C. transfer of energy from
one form to another is not 100% efficient
B. energy is always
conserved D. hit with the same force, a
tennis ball will move faster than a bowling ball
10. Which of the
following best expresses
A. the rate at which an object accelerates is directly
proportional to the force applied to it
B. the gravitational force of attraction is higher for
larger objects closer together
C. an object at rest will remain motionless unless acted
on by a force
D. energy cannot be created or destroyed
50. Solar radiation has a central role in many of Earth's
systems, such as the (a)- biosphere, (b)- atmosphere, (c)- hydrosphere/hydrologic
cycle). In well-written paragraph(s),
for each of these 3 systems explain
a major process/mechanism by which solar radiation is important to the
operation of the system, with as much detail as possible. (for example, if you
feel photosynthesis is a major process/mechanism for one of the systems, you
would want to describe the specific components of photosynthesis, perhaps even
including an equation) [18 pts]
