Water Pollution Doodle Note

What is point source pollution?

• Pollution that is spread out over a large area and cannot be traced to a single location.

• Pollution that can be traced back to a specific point such as a discharge pipe or treatment plant.

• Pollution that is caused by natural sources like volcanoes and wildfires.

• Pollution that is generated by mobile sources like cars and airplanes.

What is non-point source pollution?

• Pollution that can be traced back to a specific point such as a discharge pipe or treatment plant.

• Pollution that is generated by mobile sources like cars and airplanes.

• An aggregate of pollution from a large area such as farms or parking lots.

• Pollution that is caused by natural sources like volcanoes and wildfires.

Which of the following is NOT a category of pollution by composition?

• Nutrient pollution

• Thermal pollution

• Light pollution

• Chemical pollution

Why can cold water hold more dissolved gases compared to warm water?

• Cold water has a higher density

• Cold water has a lower pH

• Cold water molecules are more stable

• Cold water has a higher specific heat

How can the erosion of sediment into waterways be accelerated?

• By natural disasters like earthquakes and volcanic eruptions

• By certain land uses like agriculture and construction areas

• By the planting of more trees and vegetation

• By the reduction of human activities near waterways

What effect does added sediment have on aquatic ecosystems?

• It increases the oxygen levels in the water

• It enhances the growth of aquatic plants

• It reduces light penetration and disrupts benthic habitats

• It purifies the water by absorbing pollutants
