The Impact of Acid Rain

The video discusses acid rain, a type of precipitation with high acidity due to sulfur dioxide and nitrogen oxide emissions. These emissions mainly result from human activities like burning fossil fuels. Acid rain can occur as wet or dry deposition, affecting soil, water, plants, and buildings. It poses risks to ecosystems, aquatic life, and human health. Solutions include Flue Gas Desulfurization and international treaties to reduce emissions.

What are the primary human activities that accelerate the production of sulfur dioxide and nitrogen oxides?

• Photosynthesis and respiration

• Oceanic evaporation and condensation

• Volcanic eruptions and lightning strikes

• Fossil fuel combustion and industrial emissions

Which type of acid deposition occurs in the absence of atmospheric moisture?

• Hail deposition

• Fog deposition

• Dry deposition

• Wet deposition

How does acid rain affect fish in freshwater bodies?

• It increases the oxygen levels in water

• It raises the water temperature

• It enhances the growth of aquatic plants

• It prevents fish eggs from hatching at low pH levels

What is one of the health issues in humans linked to increased fine particles from acid rain?

• Asthma and bronchitis

• Stronger bones

• Enhanced vision

• Improved digestion

What is Flue Gas Desulfurization (FGD) used for?

• Generating more fossil fuels

• Enhancing nitrogen oxide production

• Removing sulfur compounds from smokestack emissions

• Increasing sulfur emissions
