What is the main difference between population growth and population explosion?

Answer and explanation

Correct answer: Explosion indicates very rapid and pressure creating growth

Direct answer: Option B is correct. Population growth means a change in the number of people over time; it may be slow, moderate or rapid. Population explosion is a much faster and unusually large increase that can create serious pressure on food, housing, water, employment, education, health services and other resources when supply does not keep pace. Therefore, every population explosion is a form of population growth, but every kind of growth is not an explosion. Option A is wrong because normal or slow growth need not create explosive pressure. Option C is wrong because growth is not only the death rate; it is affected by births, deaths and migration. Option D is wrong because an explosion specifically refers to a sharp increase in population. Memory cue: growth is the broad idea; explosion is exceptionally rapid growth with strong pressure.
