10.1 Using the Earth's resources and obtaining potable water

• What are the Earth's main resources that are vital for human survival and development?

  Water, minerals, fossil fuels, plants
• Fossil fuels are primarily used for transportation and industrial processes.


  True
• Water from lakes, rivers, and other surface sources is called surface water.
• Capturing and storing rainwater is called rainwater collection.
• Filtration systems in cities and homes remove most suspended solids and some microbes.
• Converting waste materials into new products is called recycling.
• Recycling converts waste materials into new products.


  True
• Recycling helps conserve natural resources.


  True
• Potable water is water that is safe to drink
• Desalination is the process of removing salts from seawater
• What does filtration remove from water?

  Suspended solids, microbes
• Reducing resource consumption lowers waste and saves money.


  True
• Extracting water from surface sources can damage aquatic ecosystems.


  True
• Water conservation, wastewater treatment, and sustainable water management can minimize environmental impacts.


  True
• What are minerals used for in human society?

  Manufacturing, construction, technology
• What is potable water?

  Water safe to drink
• What is desalination?

  Removing salts from seawater
• What does sedimentation remove from water?

  Larger particles and turbidity
• What is the primary goal of sustainable resource management?

  Ensure long-term resource availability
• Reducing resource consumption is known as reduce
• Using products multiple times without processing is called reuse
• Match the resource with its uses:

  Minerals ↔️ Manufacturing, construction, jewelry

  Fossil Fuels ↔️ Energy production, transportation

  Plants ↔️ Food, medicine, shelter
• What is the source of groundwater?

  Water stored underground
• Match the water treatment method with its process:

  Sedimentation ↔️ Suspended particles settle out

  Filtration ↔️ Water passes through layers

  Chlorination ↔️ Adds chlorine to kill microbes
• What is the primary goal of sustainable resource management?

  Balance resource use
• Overuse of water resources can lead to water scarcity
• Wastewater discharge can contaminate water bodies and soil
• Water is used for drinking, agriculture, industrial processes, and energy production
• Match the Earth's resource with its uses:

  Water ↔️ Drinking, agriculture

  Minerals ↔️ Manufacturing, construction

  Fossil Fuels ↔️ Energy production, transportation

  Plants ↔️ Food, medicine
• Groundwater is often naturally filtered and requires less treatment than surface water.


  True
• Steps in water treatment methods

  1️⃣ Sedimentation

  2️⃣ Filtration

  3️⃣ Chlorination
• Chlorination ensures water is safe to drink by killing bacteria and viruses.


  True
• Match the sustainable strategy with its description:

  Reduce ↔️ Minimizing resource consumption

  Reuse ↔️ Using products multiple times

  Recycle ↔️ Converting waste into new materials
• What are the benefits of reducing resource consumption?

  Lowers waste, saves money
• What are some uses of water as a resource?

  Drinking, agriculture, industry
• Surface water requires treatment to remove impurities before drinking.


  True
• Rainwater collection involves capturing and treating rainwater for drinking.


  True
• Water treatment methods ensure water is safe to drink
• Match the sustainable resource management strategy with its description:

  Reduce ↔️ Minimize resource consumption

  Reuse ↔️ Utilize products for original or different purposes

  Recycle ↔️ Convert waste into new materials
• Why does pumping and treating water contribute to greenhouse gas emissions?

  It requires energy
