EARTHQUAKE DISTRIBUTION

• What are the three main layers of the Earth?

  Crust, Mantle, Core
• How is the interior of the Earth divided?

  Based on chemical and physical properties
• What is the composition of the Earth's outer crust?

  Silica-rich and solid
• What characterizes the mantle of the Earth?

  It is highly viscous
• What does the core of the Earth consist of?

  A liquid outer core and a solid inner core
• What is the lithosphere composed of?

  The crust and the uppermost layer of the mantle
• Why does the continental crust float higher than the oceanic crust?

  Because of density difference
• What is the movement of the lithosphere called?

  Tectonics
• How many major tectonic plates are there on Earth?

  15 major plates
• What happens to tectonic plates during their motion?

  They collide, pull apart, or scrape against each other
• What does the term "tectonic" refer to?

  The deformation of the crust as a consequence of plate interaction
• What are the characteristic tectonic features produced by plate interactions?

  Mountain ranges, volcanoes, and rift valleys
• Name the seven primary tectonic plates.

  Eurasian Plate, Indo-Australian Plate, Pacific Plate, North American Plate, South American Plate, African Plate, Antarctic Plate
• List the eight secondary tectonic plates.

  Juan de Fuca Plate, Nazca Plate, Cocos Plate, Caribbean Plate, Philippine Plate, Arabian Plate, Indian Plate, Scotia Plate
• What geological processes occur at the margins of tectonic plates?

  • Formation of major mountain ranges
  • Creation of active volcanoes
  • Occurrence of earthquake epicenters
• What is the significance of observing earthquake epicenters, volcanoes, and mountain ranges in relation to tectonic plates?

  They are often located close to each other due to plate interactions
• What should one remember about the motion of tectonic plates?

  They are in constant motion
• How do tectonic plate interactions affect the Earth's surface?

  They lead to the formation of mountains and volcanoes
• What activities can help in disaster preparedness during earthquakes, tsunamis, and volcanic eruptions?

  • Educating oneself about risks
  • Creating an emergency plan
  • Assembling an emergency kit
  • Staying informed about local hazards
• How can individuals contribute to government efforts in reducing damage from natural disasters?

  • Participating in community preparedness programs
  • Volunteering for disaster response training
  • Advocating for better infrastructure
  • Supporting local emergency services
• What is the purpose of hazard maps in relation to earthquakes?

  To identify areas that are prone to earthquakes
• What should one reflect on after experiencing an earthquake?

  How the experience affected them
• What is the rigid layer that can break under stress ?

  Lithosphere
• What is the path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes?

  Pacific Ring of Fire
