there is an unlimited supply of this energy source it will not run out
100
What does transformation mean?
Energy is changing from one form to another
100
What does transferring thermal energy mean?
how heat moves from one place to another

At the top of a roller coaster what type of energy is taking place?
potential (it has the potential to move)
300
What form of energy is used when the leaves fall off a tree?
gravitational
300
Why is biomass considered a renewable energy source?
because there is an unlimited supply of (plants, animal matter, wood, and garbage)-it will not run out.

Heat energy is moving through hot and cold air rising and falling. What way of transferring thermal energy is this?
convection
400
What is the difference between potential and kinetic energy?
Potential = stored, non-moving energy Kinetic = active, moving energy
400
What is the first form of energy we use when we plug a cell phone charger into an outlet?
Mechanical
400
Explain why a wind turbine is good for our environment.
because it uses a renewable energy source (the wind), and therefore does not create a lot of pollution.

When a curling iron curls a girl’s hair what type of heat transfer is taking place?
Conduction ( the curling iron has to touch the girl's hair to transfer the heat)
500

What two forms of energy do we see when a log is burning on fire?
chemical ( it is burning) and thermal ( it is producing heat)
500
Can geothermal energy be used anywhere in the world?
No. It can only be used where there are hot springs.
