What concept describes the diminishing importance of a phenomenon as distance from its origin increases?

What concept describes the diminishing importance of a phenomenon as distance from its origin increases?

• A. Temporal Decay
• B. Spatial Decay
• C. Distance Decay
• D. Distance Decay Function

Answer: (C)

Distance decay describes how the influence or importance of a phenomenon decreases as distance from its origin increases. The wording in the question matches that idea exactly—the farther away something is, the less impact or interaction it has. Temporal decay would involve time, not distance, so it doesn’t fit. A spatial decay term is often used as a shorthand, but the standard label for this effect in geography is distance decay. A distance decay function is simply the mathematical form used to model this relationship, but the concept itself is distance decay.
