q1 sci plate tectonics

• outermost layer of the earth


  crust
• the crust and upper mantle make up the 


  lithosphere
• continuosly moving part of earth's crust


  plate
• theory stating the entire crust is broken and continuously moving

  plate tectonics
• 1. Which of the following is NOT a result of Plate Tectonics?earthquake B. fault lines C. landslides D. mountains

  landslides
• 1. Which statement about the Earth’s crusts is CORRECT?
  2. Continental and oceanic crusts have the same weight
  3. B. Continental crust is heavier than oceanic crust.
  4. C. Continental crust is thicker than oceanic crust.
  5. D. Oceanic crust is thicker than continental crust

  continental crust is thicker than oceanic crust
• earthquake type that happens when shifting of earths plates is driven by sudden release of energy within some limited region of the rocks of earth

  tectonic
• how are tsunamis created

  a submarine earthquake causes a huge amount of water to be displaced
• a landmass that projects well above its surroundings is a mountain. What do you call a chain of mountains


  mountain range
• location on the earths surface directly above the focus of an earthquake

  epicenter
• plate that pushes the philippine plate towards the eurasian plate

  pacific plate
• safest thing to do in an earthquake

  get under the strongest piece of furniture
• why is it important to be aware of places prone to earthquakes

  to perform necessary precautions
• location of the majority of earthquake epicenters relative to the location of volcanoes

  same location
• relation the distribution of mountain ranges, earthquake epicenters, and volcanoes

  mountain ranges are found in places where volcanoes and/or earthquake epicenters are also situated
• Which ocean has the ring of volcanoes around it?

  pacific
• famous philippine volcano that violently erupted in 1991

  pinatubo
• all of these plates are in the pacific ring of fire except

  1. cocos
  2. eurasian
  3. nazca
  4. north american

  northamerican
• location of epicenters, active volcanoes and moving plates in the ring of fire

  same location
• region where all risks (tsunamis, volcanic eruptions, landslides, earthquakers) are present


  region 3
• common precursor of natural disasters

  earthquakes
• safest place in philippines due to low risk in disasters

  palawan
• region prone to earthquakes but not volcanic eruption

  northern mindanao
• province where people shouldn't build high rise houses

  benguet
• All of these are wise practices during an earthquake EXCEPT_______.

  1. cover your head
  2. duck under the table
  3. park your car
  4. run to a tall tree

  run to a tall tree
• a tsunami comes when ocean water suddenly moves away from the beach
• how to save yourself from tsunami

  run to nearest hill or mountain
• worst, irreversible effect of failure to prepare for natural disasters

  death
• continental crust - thicker, less dense

  oceanic crust - thinner, denser
• plate tectonics theory is proposed by

  alfred wegener
• the lithosphere is divided into continent-sized plates that are constantly moving
• supercontinent - pangaea
• lithospheric plates move 1-2 inches per year
• where plates meet


  boundaries
• convergent


  plates collide
• transform

  slide past one another
• divergent

  move apart
• volcanoes and mountains form from

  convergent boundaries
• earthquakes and tsunamis are from

  convergent and transform boundaries
• fissures, cracks, and rifts in the surface occur at

  divergent boundaries
