. Landfill are is a/an: (a) open area (b) high lying open area (c) open area near a river/lake (d) low lying open area
anyanavicka [17]

Answer:

d

Explanation:

Landfills are low-lying open areas specifically designed for the dumping of waste materials to be buried later.

Landfills can be for municipal/household wastes, industrial wastes, or for hazardous wastes. They are usually low lying to facilitate their burial after they must have been filled-up and they represent one of the oldest methods of disposing wastes.

<em>Landfills are not just open areas, they are low-lying as opposed to high-lying, and they are not created near rivers or lakes.</em>

<em>The correct option is, therefore, d. </em>
