Which of the following statements about the Equatorial region are correct ? 1. It is a megathermal region 2. It is a sclerophyll region 3. It is a region of high development 4. It is a region of aerial streamlets Select the correct answer using the code given below :

The Equatorial region is characterized as a megathermal region, a term used for climates with high temperatures throughout the year, supporting megathermal rainforests. Statement 1 is therefore correct. Statement 2 is incorrect because sclerophyll vegetation, characterized by hard, leathery leaves, is typical of Mediterranean climates rather than the lush, broadleaf evergreen forests of the equator [2]. Statement 3 is incorrect as equatorial regions are historically associated with low levels of economic development due to harsh climatic conditions and dense vegetation [1]. Statement 4 is correct; the region is known for 'aerial streamlets' or strong vertical atmospheric convection currents driven by intense solar heating, which lead to daily heavy convectional rainfall [1]. These rising air currents are a hallmark of the Intertropical Convergence Zone (ITCZ). Thus, statements 1 and 4 are the only correct descriptions.
