  • True or False: The center of the planet is very hot. Solar energy makes use of this heat.
    False: It should be geothermal energy.
  • Give three human activities that contributes to climate change.
    deforestation, livestock farming, burning of fossil fuels
  • Give 3 examples of renewable energy sources.
    solar, wind, biomass, hydroelectric, geothermal
  • Give one advantage of using solar energy.
    does not release pollutants; may reduce electricity bill
  • True or False: The cooler the water, the more intense the storm.
    False: It should be 'The warmer the water, the more intense the storm.'
  • Give 3 examples of fossil fuels.
    coal, natural gas, oil/ petroleum
  • Too much greenhouse gases in the atmosphere can cause the rise in the planet’s temperature called ______ ________.
    global warming
  • Too much carbon dioxide in the oceans can lead to ____ ________. When this happens, the calcium carbonate in marine organisms can dissolve.
    ocean acidification
  • Give one disadvantage of using solar energy.
    Expensive when you first buy them; No solar power at night and in cloudy days
  • ____ _____ trap air in our atmosphere.
    greenhouses gases
  • ________ are created as remains of ancient plants and organisms decayed millions of years ago, under huge amounts of pressure and heat
    fossil fuels
  • ______ rocks are formed when magma cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust
    igneous
  • True or False: Geothermal renewable energy comes from building dams on rivers.
    False- It should be hydroelectric.
  • True or False: Melting of sea ice will significantly raise sea level.
    False: It should be land ice.
  • ____ rocks is formed when  it is exposed to high heat, high pressure, or to a hot, mineral-rich fluid. The existing rock must remain solid and not melt.
    metamorphic
  • We can undo the damages caused by extracting coal and petroleum.
    False: The damage is irreversible.
  • ______ rocks are composed of many, smaller rocks. They are formed through weathering and erosion.
    sedimentary
  • True or False: The amount of sea level rise is the same in all places.
    False: Sea level rise depends on many factors like ocean currents and land height. Sea level rise in the Philippines may be faster than global average.
