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.

Multiple choice

  1. Industrial waste

  2. Agricultural runoff

  3. Sewage discharge

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

Agricultural runoff, containing fertilizers, pesticides, and animal waste, is the primary cause of water pollution.

Multiple choice

  1. Industrial waste

  2. Consumer products

  3. Agricultural runoff

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

Consumer products, such as single-use plastics and packaging, are the primary cause of plastic pollution.

Multiple choice

Which of the following is a major environmental impact of rice cultivation?

  1. Deforestation

  2. Water pollution

  3. Greenhouse gas emissions

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rice cultivation can lead to deforestation, water pollution, and greenhouse gas emissions. Deforestation occurs when forests are cleared to make way for rice paddies. Water pollution occurs when fertilizers and pesticides used in rice cultivation run off into waterways. Greenhouse gas emissions occur when rice paddies release methane, a potent greenhouse gas, into the atmosphere.

Multiple choice

What is the primary environmental concern associated with hydropower?

  1. Greenhouse gas emissions

  2. Habitat fragmentation

  3. Water pollution

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

Hydropower dams can block fish migration routes and fragment aquatic habitats, leading to a decline in biodiversity.
