    • What is thermal pollution?
      Heated water discharge
    • Hot thermal pollution reduces oxygen solubility in water.
    • Hot thermal pollution reduces oxygen solubility and alters species distribution.
    • How does cold thermal pollution affect aquatic organisms?
      Slows metabolic rates
    • Order the main sources of thermal pollution based on their primary contribution to temperature change.
      1️⃣ Industrial Discharge
      2️⃣ Power Plants
      3️⃣ Urban Runoff
      4️⃣ Deforestation
    • Match each source of thermal pollution with its specific impact on water bodies.
      Industrial Discharge ↔️ Disrupts ecosystems, harms aquatic life
      Power Plants ↔️ Reduces oxygen levels, causes thermal shock
      Urban Runoff ↔️ Increases water temperature, contaminates water
      Deforestation ↔️ Raises water temperature, alters habitats
    • What is the primary effect of reduced oxygen levels due to thermal pollution?
      Hypoxia
    • Oxygen solubility decreases as water temperature increases.
    • Oxygen solubility decreases as water temperature increases
    • How does thermal pollution affect metabolic rates and reproduction of aquatic organisms?
      Disrupts enzyme activity
    • What are the main industrial processes that contribute to thermal pollution?
      Power plants
    • Match each source of thermal pollution with its specific contribution to water temperature change.
      Industrial Discharge ↔️ Heated or cooled water
      Power Plants ↔️ Warm water
      Urban Runoff ↔️ Heated water from surfaces
      Deforestation ↔️ Increased solar radiation
    • Industrial discharge releases heated or cooled water, disrupting ecosystems and harming aquatic life.
    • Power plants use water for cooling and discharge warm water, reducing oxygen levels.
    • How does deforestation contribute to thermal pollution?
      Increases solar radiation
    • What is one major source of thermal pollution listed in the study material?
      Urban Runoff
    • One main source of thermal pollution is Industrial Discharge.
    • Order the main sources of thermal pollution from most common to least common according to the study material.
      1️⃣ Industrial Discharge
      2️⃣ Power Plants
      3️⃣ Urban Runoff
      4️⃣ Deforestation
    • Industrial discharge can release water that is either heated or cooled.
    • Power plants use water for cooling and discharge warm water, which reduces oxygen levels.
    • What is the impact of industrial discharge on water bodies?
      Disrupts ecosystems
    • Power plants release warm water that can cause thermal shock in aquatic life.
    • Match the source of thermal pollution with its impact on water bodies:
      Power Plants ↔️ Reduces oxygen levels
      Urban Runoff ↔️ Contaminates water
      Deforestation ↔️ Alters aquatic habitats
    • What happens to oxygen solubility in water as temperature increases?
      Decreases
    • A power plant discharging heated water can cause native fish to migrate while invasive species like carp flourish.
    • Increased soil temperature from thermal pollution can disrupt plant growth.
    • Match the effect of thermal pollution on terrestrial ecosystems with its impact:
      Plant Growth ↔️ Reduced yields
      Soil Microorganisms ↔️ Altered nutrient cycling
    • What is the purpose of cooling towers in mitigating thermal pollution?
      Release heat into atmosphere
    • Cooling ponds are a cost-effective method to cool water naturally.
    • Reforestation reduces water temperature by providing shade.
