  • The food we eat contains __________ energy.
    chemical energy
  • In solar energy, solar panels transform the heat energy into _________ energy.
    electrical
  • In hydroelectric energy, the water moves the turbine and kinetic energy is transformed into...
    electric energy
  • Nuclear energy produces _________ as a negative consequence.
    radioactive waste
  • Fossil fuels are formed from...
    plants and animals
  • What measures the chemical energy stored in food and drink?
    calories
  • What is it called when particles vibrate and produce energy that travels in waves to your ears?
    electrical energy
    sound energy
    radiant energy
    mechanical energy
  • Name 4 examples of renewable energy resources
    Hydroelectric energy, solar energy, wind energy, and biofuels energy
  • Which type of energy source is better for the environment (Renewable or non-renewable)? Why?
    Renewable; they produce less pollution
  • What is it called when gases in the Earth's atmosphere (like CO2) store heat from the sun?
    The greenhouse effect
  • What type of energy is the sum of kinetic and potential energy?
    electrical energy
    mechanical energy
    sound energy
    radiant energy
  • The more calories a food has got, the more _________ it contains.
    energy
  • T/F: Renewable energy resources are LIMITED resources.
    FALSE: Renewable energy resources are unlimited resources.
  • Where does solar energy come from?
    The sun
  • In wind energy, the wind turbines convert wind energy into __________ energy.
    electrical
  • ____________ makes things happen. There are many forms of this.
    ENERGY
  • Which energy is in the form of electromagnetic waves?
    sound energy
    electrical energy
    mechanical energy
    radiant energy
  • What do we use to produce nuclear energy?
    uranium
  • In hydroelectric energy, water is stored in RESERVOIRS. This waster has ________ energy.
    potential energy
  • Our bodies transform chemical energy into ___________ energy and ________.
    kinetic energy and heat
  • Which type of energy sources CANNOT be replaced after we use them?
    non renewable energy sources
  • Where do biofuels come from?
    Plants or animals waste products
  • What is the movement of small charged particles called electrons?
    sound energy
    radiant energy
    mechanical energy
    electrical energy
  • Natural gas can also be used to generate...
    electricity
  • T/F: Natural gas can be used for heating and cooking
    True
  • Explain why hydroelectric energy is RENEWABLE.
    The water evaporates and forms clouds. Then, the water falls back to Earth as rain and flows into the reservoirs.
  • What are four consequences of the CLIMATE CRISIS?
    (1) loss of habitats (2) hurricanes become more powerful (3) heatwaves cause dangerously hot weather (4) heavy rain causes more floods
  • Biofuels energy can be BIOMASS. This can be... (what forms can it take?)
    solid, bioliquid, or biogases
  • Name four examples of non renewable energy sources.
    Petroleum, natural gas, coal, and uranium
  • In hydroelectric energy, stored water falls down water pipes. The falling water has got _________ energy.
    kinetic energy
  • The greenhouse effect makes the Earth [ warmer / colder ] than it would be without an atmosphere.
    Warmer
  • Petroleum, natural gas, coal, and uranium are examples of...
    non renewable energy sources
