What does population growth rate show?

Answer and explanation

Correct answer: The speed at which the population is changing

Direct answer: Option A. Population growth rate shows how quickly the size of a population changes over a given period. It is often expressed as a percentage change per year, although the exact method depends on the data used. The change may result from natural increase, which is births minus deaths, and from migration into or out of the area. A positive rate means the population is increasing, a rate near zero means little change, and a negative rate means the population is decreasing. Option B is wrong because river length is a physical measurement. Option C is wrong because rainfall is a climate measurement. Option D is wrong because mountain height is a relief measurement. The word ‘rate’ is the key: it describes change in relation to time, not the size or height of a physical feature. Memory cue: growth rate = how fast population changes, not what the landscape measures.
