10.1 Using the Earth's resources and obtaining potable water

• Renewable resources can be replenished or regenerated over time
• Examples of renewable resources include sunlight, wind, water, and biomass
• What is the purpose of waste reduction in sustainable resource management?

  Minimize waste generation
• Sustainable resource management ensures future generations can meet their needs.


  True
• Filtration, sedimentation, and chlorination are commonly used in municipal water treatment plants
• Non-renewable resources can be replenished over time.

  False
• What are Earth's natural resources?

  Materials and substances used by humans
• Order the following sustainable resource management practices from most to least impactful:

  1️⃣ Renewable Energy

  2️⃣ Sustainable Agriculture

  3️⃣ Recycling

  4️⃣ Waste Reduction
• Order the steps in the water purification process to obtain potable water:

  1️⃣ Filtration

  2️⃣ Sedimentation

  3️⃣ Chlorination
• Match the water purification method with its effectiveness:

  Filtration ↔️ Removes sediment and debris

  Sedimentation ↔️ Clarifies water by settling solids

  Chlorination ↔️ Kills harmful bacteria
• Match the waterborne disease with its description:

  Cholera ↔️ Caused by contaminated water

  Typhoid fever ↔️ Bacterial infection from water
• Water scarcity is often caused by uneven distribution, population growth, and climate change.

  True
• Water pollution can be caused by industrial waste, agricultural runoff, and improper waste disposal.


  True
• What are Earth's natural resources used for by humans?

  Various purposes
• What are three examples of non-renewable resources?

  Fossil fuels, minerals, metal ores
• Sustainable agriculture maintains soil health and conserves water.


  True
• Sedimentation clarifies water by allowing heavy particles to settle at the bottom.


  True
• Non-renewable resources can be easily replaced once used.

  False
• What is the primary goal of sustainable resource management practices?

  Meet current needs
• Fossil fuels are classified as non-renewable resources
• Steps in the process of water purification to obtain potable water:

  1️⃣ Filtration

  2️⃣ Sedimentation

  3️⃣ Chlorination
• How are Earth's natural resources classified?

  Renewable or non-renewable
• Why is sustainability and conservation crucial for natural resources?

  Ensure long-term availability
• Non-renewable resources can be easily replaced once used.

  False
• What is the purpose of recycling in sustainable resource management?

  Reduce waste and new resource use
• What does sedimentation remove during water purification?

  Suspended solids
• Boiling, UV treatment, and reverse osmosis are other methods of water purification
• How does water pollution impact the environment?

  Harms aquatic ecosystems
• Match the challenge with its description:

  Water Pollution ↔️ Contamination by industrial waste

  Water Scarcity ↔️ Demand exceeds available supply
• Promoting efficient water use and reducing waste are crucial for managing limited water resources
• Match the resource category with its definition:

  Renewable resources ↔️ Resources that can be replenished over time

  Non-renewable resources ↔️ Resources that cannot be easily replaced once used
• Sustainability and conservation are crucial for long-term resource availability.


  True
• What is the purpose of recycling in sustainable resource management?

  Reduce waste and new extraction
• What are the three key steps in the water purification process to obtain potable water?

  Filtration, sedimentation, chlorination
• Why is chlorine added to water during purification?

  To kill harmful bacteria
• Reverse osmosis is highly effective but expensive, and it produces waste water.

  True
• What is potable water?

  Safe drinking water
• What are some environmental consequences of water pollution?

  Harm to aquatic ecosystems
• Steps to address water scarcity and pollution

  1️⃣ Invest in water infrastructure

  2️⃣ Implement water treatment technologies

  3️⃣ Educate the public on water conservation
• What is Singapore's NEWater program?

  Water recycling system
