10.1 Using the Earth's resources and obtaining potable water

• What is a renewable resource?

  Can be replenished naturally
• Wind is an example of a renewable resource.


  True
• Non-renewable resources have a limited supply and cannot be replenished naturally
• Match the resource type with its characteristic:

  Renewable ↔️ Replenished naturally

  Non-renewable ↔️ Limited supply
• What are the primary sources of water used for potable water production?

  Rivers, lakes, groundwater, seawater
• Chlorination is used to kill harmful bacteria in water.

  True
• Arrange the methods to make water potable in the correct order:

  1️⃣ Filtration

  2️⃣ Chlorination

  3️⃣ Distillation
• Electricity is one of the energy sources used for water purification
• Chlorine is commonly used as a chemical disinfectant in water purification

  True
• Filtration removes solid particles
• Match the water purification method with its description:

  Filtration ↔️ Removes solid particles

  Chlorination ↔️ Kills harmful bacteria

  Distillation ↔️ Separates water by boiling
• Arrange the steps in the process of obtaining potable water from natural sources

  1️⃣ Filtration

  2️⃣ Sedimentation

  3️⃣ Disinfection

  4️⃣ Storage
• Filtration removes harmful bacteria from water

  False
• Match the water purification method with its description:

  Desalination ↔️ Removes salt from seawater

  Distillation ↔️ Separates water by boiling

  Chlorination ↔️ Kills harmful bacteria
• Water is an example of a renewable resource
• Non-renewable resources have a limited supply and cannot be replenished naturally


  True

  False
• Water purification methods utilize both renewable and non-renewable resources
• Fossil fuels are renewable water sources.

  False
• In water purification, filtration removes solid particles and impurities
• What is the purpose of chlorination in water purification?

  Kills harmful bacteria
• Renewable resources like solar, wind, and water can be replenished naturally
• Water conservation practices reduce water usage.


  True
• The Earth's resources are classified into two main types: renewable and non-renewable
