Question

Geothermal energy cannot meet all of our energy needs because access to geothermal energy is _________.
a. limited to certain regions.
b. the earth is not hot enough.
c. geothermal energy is intermittent.
d. geothermal sources do not have enough energy to generate electricity

Answer 1

Answer:

a. Limited to certain regions.

Explanation:

It will be wrong to say that the earth is not hot enough, geothermal energy is intermittent or this source is not enough to generate electricity. It is not the fuel, it's the earth which is continuously emitting radiation or heat and it will keep on emitting that. So it's the most consistent source of energy and is abundant enough to produce electricity. So the problem is, it's the location specific source of energy and can only be utilized at the places lying at the edges of the tectonic  plates. So the correct option is a.

Answer 2

B. Electrical energy

Among the choices given, the type of energy associated with electric currents is electrical energy. By its definition, electric current is the flow of charged particles through a conductor or a conduction medium, for example, a wire. Basically, it involves electricity. It is similar to water current but instead of water molecules, charged particles move down a conductor. These charged particles are mostly electrons which move freely and at random. When all the free electrons move in the same direction, a current is created.
