Ice-breaker

Which of these is not an energy source?

• Fossil Fuels

• Sun light

• Electricity

• Wind

Answer explanation

As it is created by transforming primary energy sources like coal, natural gas, nuclear energy, solar energy, and wind energy into electrical power, the electricity we use is a secondary energy source.

Which one of these is a sustainable source of energy?

• Uranium

• Fossil fuels

• Stars

• Natural gas

Which of these types of energy is non-renewable?

• Geo-thermal energy

• Wind energy

• Hydropower

• Chemical energy

Which one of these is the most energy efficient?

• Solar energy

• Wind energy

• Nuclear energy

• Geothermal energy

Which of the following is true about geothermal energy?

• It's not location specific

• It's a renewable source of energy

• It comes from the heat in the Earth's core which creates reservoirs of hot water

• It's a non-renewable source of energy

At present, is nuclear energy considered sustainable or unsustainable? Why?

• Unsustainable, because it emits greenhouse gases

• Unsustainable, because there is a limited amount of the required fuel on Earth

• Sustainable, because it doesn't emit greenhouse gases

• Sustainable, because there is an abundance of Uranium on Earth

Nuclear fission is a process where the nucleus of an atom splits into two smaller nuclei.

• True

• False

What is the device which converts sun slight to electrical energy?

• Electric Generator

• Wind turbine

• Solar panels

• Solar cell

Which one occurs in the Sun?

• Nuclear fission

• Nuclear fusion

Answer explanation

When two atoms collide to create a heavier atom, such as when two hydrogen atoms combine to create one helium atom, this process is known as fusion. This process generates enormous amounts of energy, many times more than fission, and powers the sun.

Which type of energy will be the best in the long term?

• Solar energy

• Nuclear energy

• Wind energy

• Chemical energy
