SCIENCE

• The only planet in the universe where life is possible

  Earth
• The first layer, made up of several large and small plates


  Crust
• The widest layer, made up of magma

  Mantle
• The central layer 


  Core
• The liquid layer


  Outer Core
• The solid layer


  Inner Core
• The shaking of the ground

  Earthquake
• Happens with a strong volcanic eruption while a tectonic earthquake is caused by the movement of the earth's crust

  Volcanic Earthquake
• The motion of the ground during an earthquake is measured by an instrument 


  Seisomograph
• It refers to the amount of energy released by an earthquake from its focus

  Magnitude
• The break in the ground caused by the pressure of the moving rocks

  Focus
• The ground above the focus

  Epicenter
• In measuring earthquakes magnitude, we use

  Richter Scale
• Richter Scale was developed by who?

  Charles F. Richer, an American seismologist
• Detected only by the seismograph 


  0-1.9
• Hanging objects may swing

  2-2.9
• Comparable to vibrations of a passing truck

  3-3.9
• May break windows, cause small or unstable objects to fall

  4-4.9
• Damage to well-built structures, severe damage to poorly built ones

  5-5.9
• Chunks of plaster my fall from walls

  6-6.9
• Building displaced from foundations: cracks on Earth's surface: underground pipes are broken

  7-7.9
• Bridges destroyed, few structures left standing 


  8-8.9
• Near total destruction 


  9 and above
• Refers to the effects of the earthquake as shown in the destruction of buildings

  Intensity
• This is due to our country's location in the area where crustal plates are weak. What are is this?

  Circumpacific Belt or the Pacific Ring of Fire
• Season


  The period of the year that is usually characterized by a particular kind of weather
• Seasons in the Philippines


  • Wet season
  • Dry season
• Wet season


  • Pronounced rainy season with thunderstorms
  • Starts in June, peaks in July to September, falls slowly towards end of year
  • Hot and humid weather
  • Heavy rains and typhoons
• Dry season


  • Hot and cloudless days
  • Between January and May
  • Occasional rain showers
  • Cold and dry in January to February
  • Peak in April with less rain
• The Philippines has warm and humid climate year-round
• The Philippines is considered to have one of the world's healthiest tropical climates
• Prevailing winds


  Winds that blow mostly from a single direction
• Prevailing winds in the Philippines


  • Southwest monsoon (Habagat)
  • Northeast monsoon (Amihan)
• Southwest monsoon (Habagat)


  Occurs during wet season, enhances rainfall
• Northeast monsoon (Amihan)


  Occurs during dry season, brings cool and dry weather
• The Philippines' location near the equator means it receives vertical rays of sunlight, causing evaporation and rainfall
• Activities suited for dry season


  • Family gatherings and outings
  • Travel to historical places and scenic areas
  • Recreational activities like hiking, swimming, mountain climbing
  • House cleaning, washing and drying clothes
  • Gardening and yard improvement
  • Harvesting and drying crops
  • Drying caught fish
  • Community activities like team-building, fiestas, parades, contests
  • Government construction and road repair
• Activities suited for wet season


  • Indoor activities like reading, writing, playing music, blogging, chatting, video games
  • Planting crops for farmers
• Season


  A subdivision of the Year marked by changes in weather, ecology and hours of daylight
• Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution
