Solar,wind,hydroelectric power
What is solar energy
Energy that is generated by the sun heating the solar panel
What is wind energy
When the wind pushes turbines which generates electricity
What is Hydroelectric Energy
When water is trapped by a dam and pushed through turbines to generate energy
What are the negatives for solar energy
Manufactoring solar panels can be bad for the environment because they are made up of toxic metals like mercury,lead,cadmium,silicon
Why to tree rings change size and shape
Because of different weather conditions
What is a ecological foorprint
Impact a person or community has on the environment.Which is shown in how much land is neede o sustain their lifestyle
