M3 First Energy Quiz

Which of these are benefits of wind power?

• 
• 
• 
• 

Answer explanation

wind power = cheap

wind power = clean

wind power = no wind - no power!

wind power = needs LOTS of wind turbines

Wind power is not reliable because some days there is no wind. As a result it cannot produce energy every day.

What is a drawback of wind power?

• takes up a lot of space

• clean energy

• does not pollute the air

• low risk
  
  safe

Answer explanation

wind power:
You need LOTS of wind turbines, so wind power takes up a lot of space.

Wind power is not long-term because if there is no ​ (a)   there is no ​ (b)   .

• wind
• power
• pollute

Answer explanation

wind power = it is dependent on the weather

no wind = no power

Wind power is ​ (a)   because wind ​​ (b)   are cheap to build and the wind is ​ (c)  

• affordable
• turbines
• free!

Answer explanation

wind turbines = cheap to build

wind = free!

Reorder the following

• 
• 
• 
• 
• 

Answer explanation

wind - turbine - generator - electricity

Hydropower:

Water spins a ​ (a)   , then a turbine spins a ​ (b)   . Finally, the generator ​ (c)   electricity.

• turbine
• generator
• produces

Answer explanation

water - turbine - generator - electricity

nuclear fission = ?

• atoms splitting

• atoms joining together

Answer explanation

nuclear fission = atoms splitting apart.

When this happens, it creates lots of heat!

Atoms splitting apart = nuclear _______?

First, nuclear ​ (a)   creates heat.

Then, heating water produces ​ (b)   .
Next steam spins a ​ (c)   .

Then, then turbine ​ (d)   a generator.

Finally, the generator ​ (e)   electricity.

• fission
• steam
• turbine
• spins
• produces

What makes the turbine spin when we use nuclear power?

• steam

• smoke

• wind

• the sun

Answer explanation

Nuclear power heats water to make STEAM.
