What are the major components of population growth?

Answer and explanation

Correct answer: Birth, death and migration

Direct answer: A, birth, death, and migration. Births add new people to a population, while deaths remove people. Migration changes population size when people move into an area or move out of it. In simple form, population change is births minus deaths, plus inward migration, minus outward migration. Option A is therefore correct. Option B is wrong because soil, rivers, and mountains are physical geographical features; they may influence settlement but are not direct components of population change. Option C is wrong because language, food, and clothing describe cultural or daily-life characteristics, not the processes that change population size. Option D is wrong because the Sun, Moon, and stars are celestial bodies. Memory cue: B-D-M—births, deaths, migration—are the three processes to check whenever population change is discussed.
