Statement 1 is correct: Equatorial regions are characterized by consistently high temperatures throughout the year, fitting the definition of a megathermal climate (often represented as Af in Köppen climate classification). Statement 2 is incorrect: Sclerophyll vegetation (hard, leathery leaves adapted to dry summers) is typical of Mediterranean climates, not the humid equatorial climate. Statement 3 is generally incorrect: While there are areas of development, equatorial regions often face geographical challenges (dense forests, climate-related diseases) which historically made widespread high development difficult compared to other regions, though this is a generalization. Statement 4 is likely interpreted as a region with abundant surface drainage or small streams due to very high rainfall, which is characteristic of equatorial rainforests. The term “aerial streamlets” is unusual but in context, refers to the extensive network of small watercourses resulting from high precipitation. Therefore, 1 and 4 are the correct statements.
Equatorial regions have megathermal climates (high temperature, high rainfall) and are characterized by dense drainage networks. They do not have sclerophyll vegetation, which is typical of Mediterranean climates.
