Questions and Answers

What is the main cause of Urban Heat Islands (UHIs)?

  • Low building density in urban locations
  • Large amounts of rainfall in urban areas
  • Extensive use of natural materials in construction
  • High energy consumption in urban areas (correct)

Why do urban climates have higher temperatures compared to rural areas?

  • Extensive use of artificial materials in construction (correct)
  • More vegetation present in urban locations
  • Greater wind speeds in urban areas
  • Higher levels of precipitation in urban environments

What effect does decreased vegetation in urban areas have on the temperature?

  • Increases wind speed, thus decreasing the temperature
  • Has no impact on the temperature
  • Decreases the temperature by absorbing heat
  • Increases the temperature by reducing shading and transpiration (correct)
