What is 1.2-1.4 degrees Fahrenheit?
200
An electromagnetic force, or potential difference in charge.
What is voltage?
200
A hydraulic turbine converts the energy of flowing water into mechanical energy, then uses a generator to convert this energy into electricity.
What is hydroelectric electricity?
200
This energy source is carbon neutral and renewable but it can leave a large environmental impact below and above the site of the source.
What is hydroelectric power?
200

A land site where waste is deposited, compacted and covered with soil.

What is a landfill?
