How is the heat from the earth used to create electrical power?
a. the heat is used to boil water to spin a turbine.
b. the heat is used to make solar energy.
c. the heat is burned.
d. the heat is used to create fission.

The correct answer is option A. The heat is used to boil water to spin a turbine.

The heat from the earth is used to boil water which in turn generates steam. This steam has potential to do work so with the help of that potential it rotates a turbine. The rotating turbine then activates a generator which ultimately produces electricity. So, in short we can say that geothermal energy is converted into electrical energy through a series of inter conversions of various forms of energy.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
