GP FA3 Flashcards
Which type of water pollution is caused by the discharge of untreated sewage into rivers and oceans?
Biological pollution
Which type of water pollution is caused when heavy metals like mercury and lead are released into water bodies?
Chemical pollution
Which type of pollution is caused by excessive use of fertilizers and pesticides.
nutrient pollution
Which type of pollution is caused by improper disposal of plastic waste and littering.
plastic pollution
What is the frozen part of the hydrosphere called?
the cryosphere
What can the dumping of untreated sewage and industrial waste directly into water bodies lead to?
The growth of harmful pathogens
What is defined as excessive nutrients causing algae in water to deplete oxygen and harm aquatic life?
Eutrophication
What are the primary causes of hydrosphere pollution?
-Industrial discharges
-Agricultural runoff
-Sewage and waste water
-Plastic waste
-Oil spills
How does agricultural runoff contribute to water pollution?
Agricultural runoff contributes to water pollution by carrying fertilizers, pesticides, and animal waste into water bodies, leading to nutrient overload, which can cause worse water quality.
What are the possible solutions to reduce hydrosphere pollution?
-Enforcing stricter laws on industrial waste disposal and chemical discharges into water bodies
-Reducing the use of chemical fertilizers and pesticides
-Reducing plastic production
-Public education and awareness
What are the effects of water pollution?
-waterborne diseases
-disrupting aquatic ecosystems
-effecting industries like fishing and tourism
What are the different types of hydrosphere pollution?
-Chemical pollution: Agricultural runoff and oil pollution
-Biological pollution: Pathogens and invasive species
-Plastic pollution: Microplastics and Large debris
