Why is most water vapour concentrated in the lower part of the atmosphere?
Answer and explanation
Correct answer: Because its source is Earth surface and water bodies
Option A is correct because nearly all atmospheric water vapour enters the air through evaporation from oceans, lakes, rivers and soil, together with transpiration from plants. These sources are at or near Earth’s surface, and water vapour decreases rapidly with height because air becomes colder and condensation removes moisture. It does not come only from space, form from nitrogen, or remain fixed in the stratosphere.
