What does rate of population growth tell?

Answer and explanation

Correct answer: How fast population is changing

Direct answer: A, the rate of population growth tells how fast the population is changing during a stated period. It focuses on the speed and direction of change, not merely on the number of people present at one moment. Births, deaths, and migration can all influence this change. A positive rate generally indicates increase, while a negative rate indicates decrease. The rate is often expressed as a percentage so that populations of different sizes can be compared. Option A is correct because it directly describes the meaning of growth rate. Option B is wrong because sea depth is a physical measurement. Option C is wrong because the age of mountains belongs to physical geography, not demography. Option D is wrong because air colour is unrelated to population statistics. Memory cue: population size asks “how many?”, while growth rate asks “how fast is it changing?”
