Aquatic & Terrestrial Pollution

A) It increases because warmer water can hold more gas.

B) It decreases because the water molecules move faster, making it harder for oxygen to dissolve.

C) It remains constant as temperature does not affect gas solubility.

D) It fluctuates randomly depending on environmental conditions.

A) An increase in the solubility of oxygen, benefiting aquatic life.

B) A decrease in the population of fish due to reduced oxygen levels.

C) An increase in the growth of aquatic plants, enhancing biodiversity.

D) A decrease in the water temperature, creating a more stable environment.

A) Warmer water increases the oxygen content in compressed air tanks, making diving safer.

B) Warmer water decreases the oxygen content in compressed air tanks, increasing the risk of hypoxia.

C) Water temperature has no effect on the oxygen content in compressed air tanks.

D) Warmer water makes the air in the tanks denser, improving buoyancy.

A) A decrease in water temperature due to human activities.

B) An increase in water temperature due to natural causes.

C) An increase in water temperature due to human activities.

D) Any change in water temperature, regardless of the cause.

A) The Sahara Desert

B) The Antarctic ice sheet

C) The Great Lakes in the USA

D) The Amazon Rainforest

A) By decreasing nutrient availability in the water.

B) By increasing oxygen solubility, which promotes algal growth.

C) By reducing oxygen solubility, which can favor certain algae species.

D) By decreasing water clarity, which inhibits algal photosynthesis.

A) Reforestation projects

B) Power plants using water for cooling.

C) Decreased carbon emissions

D) Preservation of wetlands

A) By increasing vegetation cover, which cools the environment.

B) Through the heat island effect from paved surfaces.

C) By reducing water usage in urban areas.

D) By decreasing the amount of sunlight absorbed by buildings.

A) By reducing the amount of water used for irrigation.

B) Through irrigation systems that return water at a higher temperature.

C) By promoting the growth of native plant species.

D) By decreasing the use of fertilizers and pesticides.

A) Chemical filtration

B) Evaporative cooling

C) Mechanical compression

D) Solar radiation
