  1. Air pollution

  2. Water pollution

  3. Noise pollution

  4. Visual impact
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Basalt quarrying involves the use of heavy machinery and explosives, which can generate significant noise pollution.

Multiple choice

What is the primary water pollutant associated with basalt quarrying?

  1. Sedimentation

  2. Acidification

  3. Eutrophication

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

Basalt quarrying can lead to increased sedimentation in nearby water bodies due to erosion and runoff from the quarry site.

Multiple choice

Explanation

The fashion industry has negative impacts on the environment, including pollution, water consumption, and waste generation.

Multiple choice

What are the main sources of acidification?

  1. Industrial emissions

  2. Agricultural activities

  3. Forest fires

  4. Volcanic eruptions
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Industrial emissions, particularly sulfur dioxide and nitrogen oxides, are the main sources of acidification. These compounds react with water in the atmosphere to form sulfuric and nitric acids, which are then deposited on the soil.

Multiple choice

Which human activity is a major contributor to coastal pollution?

  1. Oil Spills

  2. Overfishing

  3. Deforestation

  4. Urban Runoff
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Urban runoff, carrying pollutants from impervious surfaces, is a significant source of coastal pollution, affecting water quality and marine ecosystems.

Multiple choice

Which of the following is NOT a major category of environmental impact associated with consumption?

  1. Greenhouse gas emissions

  2. Water consumption

  3. Land use change

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

Water consumption is not a major category of environmental impact directly associated with consumption patterns.

Multiple choice

Which of the following is NOT a potential environmental risk associated with CCS?

  1. Leakage of CO2 from storage sites

  2. Groundwater contamination

  3. Induced seismicity

  4. Enhanced plant growth
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Enhanced plant growth is not a potential environmental risk associated with CCS. In fact, CO2 injection can potentially enhance plant growth in certain geological formations through a process known as mineral carbonation.
