Questions and Answers

Which of the following things decrease as you descend into the ocean?
- A.
Density
- B.
Pressure
- C.
Salinity
- D.
Gasses(oxygen and carbon dioxide)
- E.
Temperature
- F.
Light
Correct Answer(s)
D. Gasses(oxygen and carbon dioxide)
E. Temperature
F. LightExplanation
As you descend into the ocean, the pressure increases due to the weight of the water above. The density also increases because colder water is denser than warmer water. Additionally, the amount of gases, such as oxygen and carbon dioxide, decreases as you go deeper into the ocean. This is because the concentration of dissolved gases decreases with increasing depth. Lastly, the amount of light decreases as you descend into the ocean because water absorbs and scatters light, making it difficult for sunlight to penetrate to deeper depths.Rate this question:

Mr. Pautler had to move classrooms so he got this huge box that was 10ft2. When he filled it with books it weighed 70 pounds. Now, this was no problem for him to carry, but as he is a scientist he was wondering what the density of the box would be. The density of the box would be _______________ lbs/ft2
Correct Answer
7
7lbs/ft2Explanation
Remember to divide Mass(weight) by density!Rate this question:
- 8.
As you descend into the ocean the density of the water increases.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
As you descend into the ocean, the pressure increases, which in turn causes the density of the water to increase. This is because the weight of the water above exerts more pressure on the water below, compressing it and increasing its density. Therefore, it is true that as you go deeper into the ocean, the density of the water increases.Rate this question:
-
- 9.
As you descend into the ocean the salinity of the water increases.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
As you descend into the ocean, the salinity of the water increases because the process of evaporation leaves behind the salt content, making the water more concentrated with salt. This phenomenon is also influenced by factors such as the location of the ocean and the inflow of freshwater from rivers. Therefore, it is true that the salinity of the water increases as you go deeper into the ocean.Rate this question:
-
- 10.
As you descend into the ocean the temperature of the water increases.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
As you descend into the ocean, the temperature of the water generally decreases rather than increases. This is because sunlight can only penetrate the top layers of the ocean, and as you go deeper, there is less sunlight and therefore less heat. Additionally, cold water from deeper parts of the ocean tends to rise to the surface, causing the overall temperature to decrease with depth.Rate this question:
-
- 11.
As you descend into the ocean the amount of light in the water increases.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
As you descend into the ocean, the amount of light in the water actually decreases. This is because sunlight can only penetrate the top layer of the ocean, and as you go deeper, less and less light is able to reach those depths. The water absorbs and scatters the light, resulting in a decrease in the amount of light available.Rate this question:
-
- 12.
Is hot or cold water denser?
- A.
Hot
- B.
Cold
- C.
Neither(they are the same)
Correct Answer
B. ColdExplanation
Cold water is denser than hot water. When water is heated, the molecules gain energy and move faster, causing them to spread out and take up more space. This increase in volume leads to a decrease in density. On the other hand, when water is cooled, the molecules slow down and come closer together, resulting in a decrease in volume and an increase in density. Therefore, cold water is denser than hot water.Rate this question:

Is salt water or fresh water denser?
- A.
Salt
- B.
Fresh
- C.
Neither(they are the same)
Correct Answer
A. SaltExplanation
There's more "stuff" or particles in salt water so it will be more dense!Rate this question:

A diver may get "the Bends" if which type of gas forms bubbles in their blood when swimming to the top too quickly.
- A.
Oxygen
- B.
Carbon Dioxide
- C.
Nitrogen
- D.
Helium
Correct Answer
C. NitrogenExplanation
When a diver swims to the top too quickly, the pressure decreases rapidly, causing nitrogen gas to form bubbles in their blood. This condition is known as "the Bends" or decompression sickness. Nitrogen is the most common gas present in the air and is also the gas that makes up the majority of the gas mixture used for diving. As the diver ascends, the nitrogen absorbed by their body tissues during the dive comes out of solution and forms bubbles, which can cause various symptoms like joint pain, dizziness, and even paralysis if not treated promptly.Rate this question:
