Hi, I was wondering if you could help me again.. i need help reviewing for my midterm and have a few questions that i am not entirely sure about.
1. As a result of the Law of Conservation of Energy, a body of
water cannot warm up more than the amount of heat added to it.
Formulate an experiment to test this hypothesis using a sample of
water in a beaker. Which method would best test this hypothesis?
a. Measure the amount of thermal energy present in the
beaker after warming the water using a heat source. Then
measure the amount of thermal energy present in the
water after heating.
b. Measure the amount of thermal energy present in the
beaker and the amount of thermal energy present in the
water. Then heat the water using a heat source and
measure the amount of heat released by the heat source.
c. Measure the amount of thermal energy present in the
beaker and then add warm water to the beaker. Then
measure the amount of energy released by the heat
source and find the difference.
d. Measure the amount of thermal energy present in the
beaker and the amount of heat added by a heat source.
Then measure the amount of thermal energy present in
the water after heating and find the difference.
I thought A was the best answer choice.
6. An underwater scuba diver looks up toward the water's surface.
She sees a buoy floating on the surface and notes its location.
She then realizes that the buoy may actually be in a different
location because she is looking at it from underwater. What is the
wave property that best explains this phenomenon?
Refraction I thought D was the best choice, however I was between B and D. 9. Loggerhead turtles need an incubation temperature between
about 28 and 32 degrees Celsius. When temperatures are higher,
more female turtles are produced. When temperatures are lower,
more males are produced. When the temperatures exceed this
range, the offspring don't develop and die. Scientists have
observed that, in Florida, 90 percent of the turtles born are
females. If global climate change continues, what is the best
prediction that can be made based on these observations?
a. Male turtles will move to cooler waters, leaving females
in warmer regions.
b. More female turtles will find mates, so the population
will increase in size.
c. The turtle population will become smaller over time.
d. The turtle population will become entirely male.
I assumed the population would become smaller due to the fact
that temperatures exceed the range of 28-32 degrees Celsius the
offspring cannot develop and die.
14. Waves transfer energy in the ocean environment. How do
waves most likely affect the abundance of aquatic organisms in
e. Waves decrease carbon dioxide availability in the
ocean, decreasing abundance.
f. Waves decrease oxygen availability in the ocean,
g. Waves increase carbon dioxide availability in the ocean,
h. Waves increase oxygen availability in the ocean,
I was not sure what the answer was to this.
18. Tidal fluctuations can affect the abundance of aquatic
organisms in an ocean environment. Which tide would have the
least impact on an abundance of aquatic organisms? a. Diurnal
I was not sure what the answer to this was.
26. The diagram below shows two waves. At which letter (A?D) on
the diagram is constructive interference going to occur? Not sure about this answer either
34. Why does the ocean appear blue in color?
is absorbing blue light.
diffracting blue light.
reflecting blue light.
refracting blue light. I assumed that it is reflecting the blue light. 36. Using the graph below, indicate what type of tide occurs in
the Gulf of Mexico. a.
Spring I am not sure about this answer. 46. Which statement best describes how varying conditions in
coastal areas affect the abundance of aquatic organisms living
a. Fewer aquatic organisms live in coastal areas because the
tides require organisms to constantly adapt to changing
b. More aquatic organisms live in coastal areas because
organisms swept away during high tide can easily return to
land during low tide.
c. More aquatic organisms live in coastal areas because tidal
processes help maintain a more constant water temperature
compared with other ocean areas.
d. Fewer organisms live in coastal areas because there is less
food and oxygen available compared with other ocean areas.
I am guessing that fewer organisms live there because there is
less food, so option D seems like the best option to me.
52. Waves are caused by wind. How would waves most likely
affect the abundance of aquatic organisms living near the shore?
Waves bring nutrients to the shore.
create nutrients along the shore.
move nutrients to deeper water.
move nutrients to shallower water. I guessed it was D because the waves bring lots of water to the
shore which most likely transports nutrients as well.
63. Most aquatic organisms are adapted to a narrow range of
salinity. Why must aquatic organisms living in coastal areas be
adapted to survive in both low and high salinity?
a. During high tide, freshwater mixes easily with ocean water,
lowering salinity. b. During low tide, the ocean water becomes concentrated,
c. Ocean currents bring in deep-ocean water with high salinity
d. Temperature fluctuations can cause changes in the salinity
levels of the water.
I chose C because it seemed to be the best answer.
84. A group of scientists build a net along a section of the river to
separate a group of foreign fish species from the rest of the river.
They wish to determine whether their experiment is a closed
system by placing a colored dye in the fish's habitat and
observing whether the dye escapes from the enclosure. Could this
experiment determine whether the system is closed or not? Justify
your answer based on the definition of a closed system.
Yes, I think this could justify if this was a closed system or not
because a close system only allows energy in and out not matter
and dye is matter.
85.Many surface military ships use sonar as one method for
detecting submarines. How would the temperature, density, and
salinity of water affect the usefulness of sonar, and why?
If the temperature of the water is too cold, the sonar clicks could
have trouble due to the sound waves not being able to travel as
fast, however if they are looking below 1,000 meters it is alright
because the pressure of the ocean compensates for the cold
temperature allowing sound to return to its normal speed. If the
water is denser then the sound will travel faster because sound is
a mechanical wave, vice versa if the water is less dense then the
sound will travel slower. I do not know how the amount of salinity
