Choose the correct statement regarding geothermal energy. a. ground water is heated to form hydrothermal resources, artificially generated hot water and steam. b. geothermal refers to heat sources on the earth’s crust. c. geothermal energy may not be strictly renewable since the heat at any location can eventually be depleted. d. geothermal energy is the use of geothermal heat for the generation of magnetism.

B. Geothermal refers to heat sources on the Earth’s crust

Explanation:

The geothermal energy is the heat that is derived from the storing of energy that creates by the earth's temperature and the earth's crust is origin for this type of energy along with the radioactive decay of the elements of the crust. Thus said to be earth's internal heat and needs to be trapped as it can get lost during the formation stages.  The temperature that occurs at the earth's core and the metal zone reaches up to 4000°C and thus the high temperature causes the rocks to melt and give rise to the temperature in the plastic mantle to get activated by the convection currents that reach the surface. Some examples of this geothermal energy are those of the hot spring and the rising lava or the magmas.

It is the doctrine that the us had the right and duty to expand throughout north america. it just means they believed they had the right to expand westward and they did! they stated with the 13 colonies and then they kept moving gaining different territories throughout the years
