Renewable And None Renewable Energy Flashcards
Wind energy
Convection currents That are caused by the warming of the earth by the sun
Definition of renewable energy
Cannot be exhausted
They rely on the Suns heat or moons gravity
They can be replaced by nature within a life time
Wave energy
Waves are produced by movement in the tides caused by the moon
Wood
Trees grow within a lifetime
They use energy from the sun threw photosynthesis
Non renewable energy
Cannot be reused
There not replaces within a lifetime
The either take to long to form Eg coal +oil or there is a limited supply on earth eg uranium
The burning of fossil fuels create greenhouses gassss co2
Where does most energy come from
The sun
How is oil formed
æ as coal only with sea animals and plants
What do Power stations use to make energy and how
They burn fossil fuels
What do energy chains help us do
Trace the oath of energy
What is the energy chain
Sun - treeslong ago - coal- power stations- light
Renewable energy sources
Sun
Gives gravitational potential to water as it evaporates the vapours rise and turn into rain the rain is collected and stored
Can u create or destroy energy
No
Explain this in terms of a ball
When it hits the ground the kinetic energy changes to heat
Explain what happens when a pendulum is up + down
When it’s high there is gravitational potential when it’s lower the energy is kinetic
