In which layer is dense air needed for sound and weather most available?
Answer and explanation
Correct answer: Troposphere
The governing concept is that atmospheric density decreases with altitude because fewer air molecules are held above each higher level. The troposphere is the lowest layer, so it contains most atmospheric mass, water vapour and dust. These features support sound transmission and weather formation. The exosphere and thermosphere are extremely thin, while the mesopause is only a boundary, so option A is correct.
