Which of the following is NOT a land resource?

a. soil

b. minerals

c. forests

d. methane

The correct answer is D, methane.

Methane is not a land resource. It is a naturally occurring gas that is formed within layers of decomposing plants and animals that are directly exposed to heat and pressure. Due to the growth of the farming industry, methane is actually one of the major green house gases that cause the destruction of the layers of the atmosphere.
