Which of the following is a sustainable practice?

a. throwing jars in the trash can
b. flushing medicine down the toilet
c. using only geothermal energy
d. leaving trash bags at a local park

The Answer Is C . Using only geothermal energy

C. Using only geothermal energy.

Explanation:

Sustainable practices are those practices which are done to utilize the natural resources in a manner so that they will remain available for the future generation too.

The use of geothermal energy is a sustainable practice this is because of the fact that it is obtain from the geosphere. It is an alternative source of natural energy. The geothermal energy is obtain from water released from a hot spring. The ground water is heated up by the hot mantle present in the earth core. The underground force and pressure liberates hot water. This form of energy can be used for heating up the buildings, constructing a natural water bath and for other uses. The utilization of this form of energy is suitable for the conservation of conventional resources like fossil fuels which are used for the generation of thermal energy. By this manner the conventional resources will be available for the future generation.

c. genetic engineering

explanation:

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
