Assertion (A): Areas lying within five to eight degrees latitude on either side of the equator receive rainfall throughout the year. Reason (R): High temperatures and high humidity cause con- ventional rain to fall mostly in the afternoons near the afternoons near the equator.

Correct answer: Both A and R are individually true and R is the correct explanation of A. Assertion (A) is true : Areas located within 5° to 8° latitude on either side of the Equator, often influenced by the In- tertropical Convergence Zone (ITCZ), experience year-round rainfall due to persistent solar heating and moisture-laden air masses. The ITCZ is a region where the northeast and southeast trade winds converge, causing warm, humid air to rise continuously. This rising air cools and condenses, leading to frequent cloud formation and precipitation. The consistent high temperatures in these regions enhance evaporation, while the abundant mois- ture ensures that convectional rainfall occurs almost daily, par- ticularly in the afternoons when the ground has heated the most. Reason (R) is true : Convectional rainfall is characteristic of equatorial regions. High temperatures during the day cause the surface air to heat up and rise (convection), cooling as it as- cends, leading to afternoon rainfall. This process is driven by the intense solar heating and high humidity near the Equator
