Geothermal energy is an alternative energy source. However, it is not resourceful enough to replace more than a minor amount of the Earth's energy needs. Why is this?

A.

Once the cool water is poured down the well and filters through the rocks, the rocks cool off and are no longer hot enough to turn water into steam.

B.

Drilling through the Earth to reach areas hot enough to create steam is possible, but very expensive and difficult.

C.

The center of the Earth is not hot enough to make a significant energy contribution.

D.

There are only a few places where the Earth's core is hot. It is cool in places like Antarctica.

Option (B)

Explanation:

Geothermal energy refers to the heat energy that is stored in the interior of the earth, and is primarily used to generate electricity. The geothermal energy increases with the increasing depth.

This energy is not that resourceful in a broad picture. It is because in order to extract this energy, the drilling and excavations must be made. And it is a very expensive process as it is very difficult to carry out the entire process.

Due to this drawback, it is much less resourceful.

Thus, the correct answer is option (B).

answer; i believe the correct answer to the above question is ( friction)

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
