(a) negatively impacts land fertility.
How does deforestation contribute to land degradation and reduced fertility?
By increasing soil erosion and nutrient loss
By promoting biodiversity and soil health
By preventing desertification and soil compaction
By enhancing water retention and nutrient cycling
How does converting green space into a commercial area affect soil fertility?
Increases soil fertility due to human activity
Causes soil erosion and degradation
Promotes biodiversity and improves soil nutrient availability
Results in the accumulation of organic matter, enriching the soil
(a) is a common source of groundwater.
What should a farmer do if the river water used for irrigation is discolored and has a strange odor? Select TWO answers.
Switch to rainwater harvesting
Install a filtration system for the river water
Test the river water for contaminants
Seek alternative water sources such as groundwater
The residents of a suburban neighborhood have been experiencing foul-smelling tap water for several weeks. They suspect contamination and are concerned about the safety of their drinking water. What action should the residents take to address the issue with their tap water? Select TWO answers.
Install a cheap water softening system.
Contact the local water utility for testing.
Boil the tap water before consumption.
Use bottled water for all household purposes
Ignore the issue as it might resolve on its own.
What effect does composting have on resource availability?
It enhances soil fertility and reduces the need for chemical fertilizers.
It increases greenhouse gas emissions and contributes to climate change.
What is the primary role of recycling in preserving finite resources?
Recycling reduces the need for raw material extraction and conserves resources.
Recycling has minimal impact on resource availability due to technological limitations.
A community garden has implemented a composting system to manage organic waste from local households. The gardeners are curious about the potential benefits of composting on resource availability. How does the practice of composting contribute to resource availability in the community garden?
It diminishes soil fertility and reduces resource abundance.
It increases reliance on synthetic fertilizers, depleting natural resources.
It enhances soil health, reducing the need for external nutrient inputs.
It has no impact on resource availability, as composting is an isolated process.
Which of the following is an example of point source pollution?
Runoff from agricultural fields
Exhaust emissions from vehicles
Discharge from a factory pipe into a river
Leachate from a landfill
What is a common cause of nonpoint source water pollution?
Industrial effluent from a specific factory
Pesticide runoff from agricultural fields
Discharge from a sewage treatment plant
Oil spills from a tanker accident
How do chlorofluorocarbons (CFCs) contribute to air pollution?
By increasing soil erosion and degradation
By raising the pH levels of water bodies
By depleting the ozone layer in the stratosphere
By lowering greenhouse gas emissions
(a) is a major contributor to global warming and climate change. Select TWO correct answers.
(b)
