Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tourism and hospitality activities can contribute to air pollution through the burning of fossil fuels for transportation and energy generation, water pollution through the discharge of wastewater and solid waste, and land degradation through the construction of hotels, resorts, and other tourist infrastructure.

Multiple choice

What is the primary cause of ocean acidification?

  1. Increased carbon dioxide levels in the atmosphere

  2. Oil spills

  3. Overfishing

  4. Coastal development
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ocean acidification is caused by the absorption of carbon dioxide from the atmosphere into the ocean. This process lowers the pH of the ocean, making it more acidic.

Multiple choice

Which human activity is a major contributor to marine pollution and poses a threat to marine ecosystems?

  1. Overfishing

  2. Pollution

  3. Climate change

  4. Tourism
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Pollution, particularly plastic pollution and oil spills, is a major contributor to marine pollution and poses a threat to marine ecosystems. Plastic pollution can entangle marine life, block digestive tracts, and leach toxic chemicals into the marine environment. Oil spills can contaminate marine habitats, affecting marine organisms and disrupting ecological processes.

Multiple choice

What is the primary concern regarding the long-term storage of CO2 in geological formations?

  1. Leakage and migration of CO2

  2. Corrosion of storage infrastructure

  3. Seismicity induced by CO2 injection

  4. Negative impact on groundwater quality
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Leakage and migration of CO2 from storage sites pose a significant risk, as it can lead to the release of CO2 into the atmosphere, potentially undermining the effectiveness of CCS technologies.

Multiple choice

Which of the following is a potential environmental concern associated with enhanced oil recovery (EOR) using CO2?

  1. Groundwater contamination

  2. Induced seismicity

  3. Release of toxic chemicals

  4. Habitat destruction
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

EOR using CO2 can potentially lead to groundwater contamination if CO2 or associated fluids leak from the injection site and migrate into aquifers.

Multiple choice

Which human activity is the primary cause of ocean acidification?

  1. Burning fossil fuels

  2. Deforestation

  3. Overfishing

  4. Plastic pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Burning fossil fuels releases carbon dioxide into the atmosphere, which dissolves in the ocean and forms carbonic acid, leading to ocean acidification.
