Hydro energy is created by...
moving water
Any material or substance that allows electricity to flow through them.
Conductor
The continuous flow of electrical charges through a material is called...
an electric current
Why does lightning often hit trees or telephone poles before hitting the ground?
Because they are closer to the clouds!
Copper is a conductor or an insulator?
Geothermal energy is created by...
steam from the Earth
A type of electric current that travels in one direction.
A direct current

Name three different ways to generate electricity
tidal, nuclear, geothermal, hydro, solar, wind, biomass,
Type of electric current that switches directions and/or flows in both directions (does not go in just one direction). Example: Powerlines
Alternating current

ONE
Cloud droplets and ice crystals collide and form larger particles called..
Graupel
Protons have a ________ charge.
Electrons have a ________ charge.
Positive = protons
Negative = electrons
What is the difference between RENEWABLE and NONRENEWABLE energy?
Renewable resources will naturally replenish themselves over time, like wind, solar, plants, trees, etc. Non-renewable will be gone forever once used, like coal, fuel, etc.
This type of electricity is created when electrons move from one place to another through friction.
Static electricity
