Earth Systems & Resources
In what way does hydroelectric power differ from fossil fuels regarding their effect on climate change?
Hydroelectricity generates power without releasing carbon dioxide after dam construction.
Oil reserves are quickly depleting, requiring extensive exploration to identify new reserves. generates power without releasing carbon dioxide during combustion.
Results in acid rain due to sulfur dioxide and effects on aquatic life after use.
What process describes how heat is transferred from one part of a fluid (like air or water) to another by a circulatory motion?
Radiation
Convection
Conduction
Cretaceous
Which investigation most accurately measures the impact of increased ultraviolet (UV) radiation on an aquatic food web due to stratospheric ozone depletion?
Measuring only the dissolved oxygen levels in water as an indicator of overall aquatic health.
Monitoring carbon dioxide absorption by phytoplankton without considering changes in UV radiation levels.
Examining the survival rates, growth patterns, and reproductive success of phytoplankton and their subsequent effects on zooplankton and fish populations.
Analyzing the behavioral changes in fish populations without assessing the condition of phytoplankton or zooplankton.
How does implementing cap-and-trade systems for carbon emissions most directly address climate change compared to other strategies?
Mandating the installation of renewable energy sources for all new industrial developments.
Offering tax credits to companies that voluntarily reduce their carbon footprint below a certain threshold.
By setting a limit on emissions and creating a market for companies to buy and sell allowances, incentivizing reductions.
Funding research into carbon capture technologies to remove existing CO₂ from the atmosphere.
When designing a study to assess how deforestation affects local climate regulation services provided by a dense forest ecosystem, what variable should be primarily measured over time?
Variations in soil pH levels pre- and post-deforestation without consideration for atmospheric conditions.
The rate at which new vegetation grows back in areas adjacent to those that were deforested.
The increase or decrease in local wildlife population sizes exclusively focusing on terrestrial vertebrates.
Changes in temperature and precipitation patterns before and after deforestation within the same geographical area.
What is a trade-off associated with relying heavily on biofuels as an alternative energy source?
Potential stimulation of rural economies through increased demand for agricultural products.
Competition with food production due to land use requirements for growing biofuel crops.
Biofuels' biodegradability leads to fewer environmental hazards when spills occur.
Decreased reliance on fossil fuels reducing greenhouse gas emissions.
Which side of a mountain may receive less precipitation because the air doesn't have moisture left?
Right side.
Leeward side.
Windward side.
Left side.

How might researchers determine if ocean acidification is influencing calcium carbonate shell formation among different marine organism trophic levels?
Studying only one species' response to changing salinity levels that result from melting polar ice caps due to global warming.
By comparing shell thickness across multiple generations of planktonic organisms, mollusks, corals, and crustaceans from varying depths with differing acidification exposures.
Monitoring exclusively coral bleaching events as an indirect measure of broader ocean chemistry alterations.
Observing feeding habits of marine predators without relating it back to prey populations with calcium carbonate shells.
What type of climate is characterized by low precipitation and high temperature variations between day and night?
Desert climate
Temperate climate
Polar climate
Tropical climate
Which outcome best exemplifies an unintended consequence of implementing geoengineering techniques such as cloud seeding to mitigate climate change effects on atmospheric patterns?
Increase in cloud albedo effect efficiently reflecting sunlight with no impact on rainfall patterns.
Immediate cooling effects that uniformly reduce global temperatures without side effects.
Altered precipitation distribution leading to droughts in regions downstream that depend on rainwater.
Enhanced agricultural productivity globally due to controlled and predictable rainfall patterns everywhere.
