module 2

• Types of natural resources


  • Renewable
  • Nonrenewable
• Renewable resources


  Materials that can be replaced easily or have the potential to be replaced over time
• Nonrenewable resources


  Natural resources that are in limited supply or once consumed, cannot be replaced
• Philippines experiences about 20 typhoons in a year on average
• Watershed


  A catchment area that drains the water into streams, rivers, lakes, and springs
• Soil


  Formed from rocks that were broken down by physical and chemical weathering along with the materials from dead plants and animals
• Philippines is the fifth mineral-rich country in the world, third in gold reserves, fourth in copper, and fifth in nickel
• Watersheds


  Areas that supply the water needed by the communities and the varied life forms in that area
• Too much rain


  Can cause floods which can wash away the top soil where plants grow
• Top soil cannot be replaced easily
• Soils are formed


  From rocks that were broken down by physical and chemical weathering along with the materials from dead plants and animals
• Philippines is recognized as the fifth mineral-rich country in the world, third in gold reserves, fourth in copper, and fifth in nickel
• Pacific Ring of Fire


  Continuing movement of very hot magma or molten materials under the ground
• The countries included in the Pacific Ring of Fire is home to approximately 75% of the world's active volcanoes
• Formation of igneous rocks


  1. Heat within the Earth causes rocks and other materials to melt forming magma

  2. When magma rises during volcanic eruptions, some of the magma does not reach the surface of the Earth but instead slowly cools and hardens forming different kinds of igneous rocks

  3. With favorable temperature and pressure conditions, the rocks containing metals melt and redeposit, eventually forming minerals
• Renewable energy resources


  • Solar energy
  • Geothermal energy
  • Hydropower
  • Wind energy
  • Biomass
• Nonrenewable energy resources


  Coal, crude oil, natural gas, and other fossil fuels
• Oil and coal were listed as the primary sources of energy in the country
• Practices that promote sustainable use of natural resources


  1. Practice the 5Rs (Refuse, Reduce, Reuse, Recycle, Recover)

  2. Save energy by conserving energy

  3. Use renewable energy resources instead of fossil fuels
• Reforestation


  The practice of planting new trees in denuded forests to keep the forests standing and provide resources
• Renewable energy sources


  Energy sources that are easily harnessed from the environment such as the sun's heat, wind power, flowing water, and heat from the earth
• Renewable energy sources do not emit air pollutants and carbon dioxide, the culprit of global warming
• Sustainability


  The practice of using natural resources wisely without wasting or using them up completely so that the future generations can benefit from them
• Reforestation


  The practice of planting new trees in areas that have been depleted
• Burning of fossil fuels contributes to air pollution and produce carbon dioxide and other greenhouse gases which can trap heat in our atmosphere contributing to global warming and climate change
