challenges of natural hazards

• What is the term used for the movement of tectonic plates that can cause earthquakes?

  Convection currents
• How do convection currents affect tectonic plates?

  They cause the plates to move.
• What happens when two tectonic plates of different densities collide?

  The denser plate subducts beneath the other plate.
• What are the three types of plate boundaries?

  • Destructive boundaries: where plates collide and one is forced under another.
  • Constructive boundaries: where plates move apart and new crust is formed.
  • Conservative boundaries: where plates slide past each other.
• What is a significant result of tectonic plate movement in mountainous regions?

  Earthquakes are caused.
• What is the role of public awareness in earthquake-prone regions?


  It helps to prepare communities for potential earthquakes.
• What is one method to protect against earthquake damage?

  Building earthquake-resistant structures.
• What is the significance of the San Andreas Fault?

  It is a well-known conservative plate boundary in the USA.
• How does climate change affect natural disasters like tropical storms?

  It can increase the intensity and frequency of such storms.
• What is a common consequence of tropical storms?

  Flooding and damage to infrastructure.
• What is the relationship between greenhouse gases and climate change?

  Greenhouse gases contribute to global warming.
• What is the impact of rising sea levels?

  It can lead to coastal flooding.
• How can communities prepare for the impacts of climate change?

  By implementing sustainable practices and improving infrastructure.
• What is the effect of deforestation on climate change?

  It contributes to increased carbon dioxide levels in the atmosphere.
