AQUA 102 Final Review Questions And Correct Answers
Week 1: Introduction to Aquatic Resources - ANSWER • Understand the importance of
water and aquatic resources to living organisms
• Describe the various Earth spheres
• Give examples of the interrelationships among the various Earth spheres
• Identify the importance of oceans as water reservoirs on Earth
• Explain the chemical composition of saltwater
• Describe the various unique characteristics of water
A shark eats a reef fish, which is then caught as bycatch in a tuna fishery. What Earth
spheres are relevant to the previous sentence:
A) geosphere and biosphere and hydrosphere
B) biosphere and hydrosphere and anthrosphere
C) hydrosphere and atmosphere and anthrosphere
D) atmosphere and biosphere and geosphere - ANSWER B) biosphere and
hydrosphere and anthrosphere
Biosphere: The biosphere encompasses all living organisms, including the shark, reef
fish, and other marine life involved in the food web within the ocean ecosystem.
Hydrosphere: The hydrosphere refers to all water on Earth, including oceans, seas,
rivers, and lakes. In this scenario, the shark and reef fish inhabit the marine
environment, which is part of the hydrosphere.
Anthrosphere: The anthrosphere represents the sphere of human influence on the
Earth, including human activities and their impacts on the environment. In this scenario,
the tuna fishery represents human intervention in the marine ecosystem, leading to the
incidental capture of the reef fish as bycatch
Consider the following scenario: An oil tanker crashes into a coral reef near a popular
tourist destination in the Caribbean. Briefly discuss the social, economic, and
, environmental issues this may have from multiple perspectives (e.g., the oil company,
the coral reef ecosystem, the local population relying on tourism). - ANSWER -
**Environmental Impact:** The immediate spillage of oil and chemicals can devastate
coral reefs, harming marine life and disrupting fragile ecosystems. Long-term effects
may include reduced biodiversity, habitat degradation, and compromised ecosystem
services such as coastal protection and fisheries support.
- **Economic Fallout:** The incident can lead to a decline in tourism revenue as visitors
avoid the affected area, resulting in financial losses for businesses reliant on tourism.
Job losses in sectors like hospitality, recreation, and transportation can exacerbate
economic hardship for local communities, potentially leading to long-term
socio-economic repercussions.
- **Social Concerns:** The spillage poses health risks for residents and workers
involved in cleanup efforts, with potential implications for public safety and well-being.
The cultural significance of the reef to indigenous communities and the emotional toll on
residents witnessing environmental degradation may exacerbate social tensions and
erode community cohesion.
- **Legal and Corporate Ramifications:** The oil company responsible for the spill may
face legal liabilities, including fines, compensation claims, and cleanup expenses.
Regulatory agencies may tighten oversight of maritime activities, leading to stricter
enforcement measures and compliance requirements. The incident can also damage
the reputation and credibility of the oil company, affecting investor confidence and
stakeholder trust.
Addressing these multifaceted challenges requires coordinated efforts from
government agencies, non-governmental organizations, industry stakeholders, and
local communities. Immediate response actions such as containment, cleanup, and
habitat restoration are essential to mitigate environmental damage and protect
vulnerable ecosystems. Additionally, long-te
Week 2: Physical and Chemical Processes - ANSWER • Give some examples of the
unique characteristics of oceans
• Describe the varied topography of the ocean floor
• Describe wave motion
• Explain the formation of surface ocean currents
• Determine the presence of upwelling and downwelling currents at a coastline
• Explain how tides form and their characteristics
• Discuss the role of waves and tides shaping shorelines
