Question 2(Multiple Choice Worth 3 points)
(01.04 MC)
There are several properties of water that make Earth a suitable environment for life, including water's high boiling point and high heat capacity. Which best explains why this characteristic of water is important for marine life?
It allows water to remain in its liquid form even at relatively high temperatures.
It allows water to vaporize easily, powering the water cycle.
It allows water to be denser, making it easy for living organisms to move through.
It allows water to resist freezing and thawing cycles.

Public Domain
A conceptual model
A mathematical model
A physical model
A theoretical model
Question 4(Multiple Choice Worth 3 points)
(02.06 LC)
Researchers have found that plants can help to reduce various emissions, including carbon dioxide, because plants convert carbon dioxide to sugar and oxygen. What is the name of this carbon cycle process?
Assimilation
Decomposition
Photosynthesis
Respiration
Question 5(Multiple Choice Worth 3 points)
(02.06 MC)
Runoff that contains fertilizers can cause increased levels of nitrogen in the ocean. What is a possible result of these increased nitrogen levels that may have harmful effects that can disrupt the diversity of ocean ecosystems?
Acid rain
Algal blooms
Algal destruction
Nitrification
Question 6(Multiple Choice Worth 3 points)
(02.02 LC)
A marine scientist concluded that the Canary Islands were not formed by volcanic activity because his data showed that the fault on which the islands lies was inactive during the islands' formation. Another scientist disagrees with his measurements and provides data showing that the fault was active at that time. How does this disagreement contribute to the scientific process?
Scientific reliability is increased when the same experiment yields different results.
Scientific logic is made more rigorous by conflicting data collected by different groups.
Scientific hypotheses are disproved when two scientists come to different conclusions.
Scientific claims are strengthened by evaluating different possible arguments.
Question 7(Multiple Choice Worth 3 points)
(01.04 MC)
Use the following data profiles to best describe the effect on density as temperature decreases and depth increases.
Data profiles illustrate temperature and depth relationship. The Thermocline profile illustrates from 500-0m the temperature rapidly increases from10-25 degrees Celsius. The Halocline profile illustrates from 500m-0m a steady increase in salinity from 34.5 to 35 percent respectively. The Pycnocline profile illustrates a density of 1.03-1.02.

As depth increases and temperature decreases, density remains constant.
As depth increases and temperature decreases, density increases.
As depth increases and temperature decreases, density decreases.
As depth increases and temperature decreases, density does not follow a trend.

The North American Plate is moving away from the Eurasian Plate, forming the Mid-Atlantic Ridge. Iceland offers a natural laboratory to scientists studying plate tectonics. Using what you know about plate tectonics, predict what boundary zone is occurring and two resulting features from the choices below.
Iceland with the North American Plate moving away from the Urasian Plate forming a Mid-Atlantic Ridge.

Question 9(Multiple Choice Worth 3 points)
(01.03 HC)
Biomass is a way to describe the overall amount of living organisms in an area. Using the figure below, choose the most likely reason for the decrease in biomass with an increase in depth and distance from the coast.
At the top of the diagram along the continental shelf and Euphotic zone are 15 units of biomass. Under the Euphotic zone is the Bathyal zone which contains 6 units of biomass. Situated below the Bathyal zone is the Abyssal zone that is home to 3 units of biomass.
There is an increase in the number of predators as you move away from the coast. The increase in predators decreases the number of other organisms.
There is an increase in oxygen away from the coast. This increases productivity and the plants compete with other organisms, leading to a decrease in biomass.
There is a reduction in the availability of nutrients away from the coast, which decreases primary production. Less producers and energy are available, leading to a decrease in biomass.
There is less pressure at depth as one moves away from the coast. This pressure makes it easier for organisms to survive and thus reduces biomass away from the coast.
Question 10(Multiple Choice Worth 3 points)
(03.01 MC)
After a volcanic eruption, lava flows on the surface of the Earth. After the lava has time to cool, scientists notice that plants are starting to grow on the lava surface. What kind of ecological process could you infer is happening and why?
Succession; the lava provides a barren land that leaves room for pioneer plants to establish and start to create an ecosystem.
Succession; the lava provides a barren land that leaves room for less hardy plants to establish and start to create an ecosystem.
Climate change; climate change causes more volcanic eruptions, which allows for plant growth.
Climate change; climate change causes less volcanic eruptions, which allows for plant growth.

Earthquakes
Submarine mountain range
Trenches
Widening of the ocean basin
