Which statement about fossil fuels is correct? (TB Pg 59 - circle the answer on your own TB)
They take millions of years to burn.
They take millions of years to form.
They cost millions of dollars.
They can only be found millions of years ago.
Which statement is not a disadvantage of fossil fuels?
Burning fossil fuels produce a lot of energy in a short amount of time.
Burning fossil fuels produce harmful gases, leading to air pollution.
Fossil fuels will run out one day as they take millions of years to form.
Mining of fossil fuels is dangerous and damages the environment.
The energy conversion when fossil fuels are burnt and used in power stations is:
electrical energy --> heat energy
chemical potential energy --> kinetic energy + heat energy
chemical potential energy --> heat energy --> electrical energy
heat energy --> kinetic energy
Wind (a) convert the kinetic energy of wind into electrical energy.
Which statement is not an advantage of wind energy?
It is clean energy as it does not produce harmful or greenhouse gases.
It is renewable and will not run out easily.
It involves a high start-up cost as it is expensive to build wind turbines.
Solar (a) convert solar energy into electrical energy.
Which statement is not an advantage of solar energy?
It is clean energy as it does not produce harmful or greenhouse gases.
It is renewable and will not run out easily.
The supply of solar energy depends on weather conditions and season.
(a) is the renewable energy that can be harnessed from plants and animals
Which statement about biomass is not correct?
It does not produce harmful or greenhouse gases when burnt.
It is renewable and will not run out easily.
As we need land to grow crops for biomass, there will be less land to grow food. This may push up the price of food.
Hydropower is harnessed when a (a) that is used to block a river is opened and water flows through to turn the water turbine and generator.
What is the energy conversion when we use hydropower?
water energy --> kinetic energy
kinetic energy --> electrical energy
electrical energy --> heat energy
heat energy --> electrical energy
Which statement is not an advantage of hydropower?
It is clean energy as it does not produce harmful or greenhouse gases.
It is renewable and will not run out easily.
It involves a high start-up cost as it is expensive to build dams.
