Question

guided practice
geothermal energy works best in regions where ______.
a. water is scarce
b. hydrogen sulfide is produced
c. salts are abundant
d. magma is near earth’s surface

Explanation:

Geothermal energy harnesses heat from Earth's interior. When magma (molten rock) is close to the surface, it heats groundwater, which can be tapped to generate electricity or for heating. Scarce water (A) would hinder geothermal systems, hydrogen sulfide production (B) is a byproduct not a requirement, and abundant salts (C) are irrelevant to the core condition for effective geothermal energy use.

Answer:

D. magma is near Earth's surface
