Geo engineering can be broken into two categories?
Carbon Capture and Storage (CCR)
Solar Radiation Management (SRM)
Carbon Capture and storage downsides? "2"
1) Very energy intensive 1/3 of power plants energy
2) Carbon wells could be disturbed.
ex. 1986 deposit killed animals within 25 miles
Solar Radiation Management(SRM) is...? What are some examples of this and what do they not address
SRM is response to warming by reducing the amount of solar radiation reaching earth surface.
Ex. Salt spraying clouds to whiten
Reflective discs
Does not address acidity of ocean water

Why is a bird able to stand on a high-voltage wire?
Because there is no potential difference across its body.
What is the name of the law that related the current, potential difference and resistance in a electric circuit.
Ohms Law
The rate at which electrical energy is delivered to a device is the power. The power delivered is equal to the _____ X current (amps). Think of Diagram.
VOltage X Amps (current)=P or Watts
As more devices are added to a series circuit, the total resistance for the circuit increases. Remember that a series is R= R1 X R2...Etc.
T or F
