Science 4th quarter

• The Philippines is gifted with a lot of natural resources due to its location and topography
• Water resources in the Philippines


  • Beaches
  • Lakes
  • Rivers
  • Swamps
• Water is very essential to life and is used for domestic activities, irrigation, industries, electricity, and fun/relaxation
• The right temperature and abundant rainfall in the Philippines make it a mega diverse country with high diversity of plants and animals
• Land resources in the Philippines


  • Soil suited for agriculture
  • Rice
  • Corn
  • Sugarcane
  • Coconut
  • Abaca
• The Philippines' location along the Pacific Ring of Fire makes it home to majestic mountains, volcanoes, and other landforms
• Minerals found in the Philippines


  • Gold
  • Copper
  • Iron
  • Nickel
  • Sand and gravel
  • Limestone
  • Marble
  • Clay
• Fossil fuels found in the Philippines include coal and natural gas
• Fossil fuels are slowly being exhausted, so alternative sources of energy are being adopted
• Clean and cheap energy resources in the Philippines

  • Solar energy
  • Wind energy
  • Hydropower
  • Geothermal energy
• Natural resources play a vital role in the Philippines' survival, so they need to be used wisely to ensure enough supply for the future
• Geographic coordinate system


  System used to locate places on Earth using degrees of longitude and latitude
• The Philippines is approximately located at 13 degrees north and 122 degrees east on the map
• Philippines


  • Country with no land borders
  • Archipelago - an area of group or chain of islands surrounded by bodies of water
  • Comprises about 7,641 islands
  • Main island groups are Luzon, Visayas, and Mindanao
  • Capital is Manila
• The Philippine archipelago is located along the Pacific Ring of Fire
• Pacific Ring of Fire


  Where mountains and volcanoes are formed and earthquakes are generated
• The Philippines experiences frequent volcanic eruptions and earthquakes due to its location on the Pacific Ring of Fire
• Bodies of water surrounding the Philippines


  • Luzon Strait (north)
  • Philippine Sea and Pacific Ocean (east)
  • West Philippine Sea/South China Sea (west)
  • Celebes Sea (south)
  • Sulu Sea (southwest)
• The Philippines experiences severe storms and typhoons due to being surrounded by bodies of water
• Land masses surrounding the Philippines


  • Japan, Taiwan, Republic of China (north)
  • Malaysia, Indonesia (south)
  • Vietnam (west)
• The location of the Philippines in relation to the surrounding bodies of water and land masses is important for its natural resources
• Seasons


  Different periods of the year that are distinguished by special weather and climate conditions
• Seasons


  • Spring
  • Summer
  • Autumn
  • Winter
• Seasons

  • Different amount of light received from the sun
  • Different temperatures
  • Different weather conditions that repeat
• Axis

  An imaginary line passing through the center of the earth that goes through both the north pole and the south pole
• Rotation

  The spinning motion of earth around its axis
• Revolution

  The movement of the earth around the sun
• It takes 24 hours or one day for the earth to completely rotate around on its axis
• It takes 365 and 1/4 days or one year for the earth to move around the sun
• Earth's axis

  • Tilted at an angle of 23.5 degrees
• Earth's axis is tilted

  Different parts of the earth receive different amounts of sunlight as the earth revolves around the sun
• Different amounts of sunlight


  Results in different temperatures and different weather conditions we call seasons
• Solstice


  When the axis of the earth points forward or away from the sun
• Summer solstice occurs on June 21 or 22, winter solstice occurs on December 21 or 22
• North pole tilted toward the sun in June


  Northern hemisphere tilted toward the sun, receives more direct rays, experiences longer daytime and warmer temperatures
• North pole tilted away from the sun in December


  Northern hemisphere receives less direct rays, experiences shorter daytime and cooler temperatures
• Equinox


  When the axis of the earth does not point either toward or away from the sun, resulting in equal day and night
• Vernal equinox is on March 21 or 22, autumnal equinox is on September 21 or 22
• Philippines climate


  Only experiences wet and dry seasons, not four seasons, due to location near the equator
• Rainy season in Philippines is from June to November, dry season is from December to May</b>
