Molly is looking for a sustainable fuel source that doesn’t require technical equipment to harness. she is concerned that trees take too long to replace through reforestation. what alternative should she consider? a. fossil fuels b. geothermal c. hydroelectric d. biomass e. tidal

B. geothermal

Explanation:

Geothermal energy is produced when the groundwater is heated by the hot mantle. This results in the production of hot water. The hot springs are located to obtain the hot water energy. The energy harnessed by this geothermal hot water springs does not require any technology and equipment.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
