Consider the following statements with reference to rainy tropical climate regions: I. These usually extend not more than five to ten degress on either side of the equator. II. These are characterised by constant high temperature and humidity with little range. III. These regions have sun overhead or nearly so throughout the year. Which of these statements are correct?

Explanation

Rainy tropical climate regions, specifically the tropical wet (Af) or equatorial climate, are primarily located within 5 to 10 degrees latitude on either side of the equator [t4][t5]. These regions are characterized by constant high temperatures (averaging around 27°C) and high humidity with a very low annual temperature range [c1][c3][t4]. The climate is dominated by the Intertropical Convergence Zone (ITCZ), which ensures the sun remains overhead or nearly so throughout the year, providing intense radiant energy across all seasons [c1][t8]. This results in heavy, year-round precipitation without a distinct dry season [t1][t8]. All three statements accurately describe the geographical extent, thermal characteristics, and solar positioning of the equatorial rainy tropical climate, making option 1 the correct choice.
