KCSE Geography Paper 1 1999 Section A Question 3.
The diagram below represents the flow of air current. Use them to answer questions below
(a) (i) In your answer booklet, name the air current marked E
sea/ lake breeze
(ii) Why does the air cools as it rises
Land losses heat faster than sea. Air upon the land becomes cooler and heavier than that upon the sea. The relatively warmer air upon the sea is lighter and therefore it rises while the cooler heavier air on the land flows towards the sea to replace the rising air.
(b) Give the reason why air cools as it rises
As air rises, it expands thus spreading out its molecules over a wider area and hence becoming cooler.
