a). Hot and wet climate throughout the year
b). Red and yellow soils of low fertility
c). Tall hardwood trees form a cover
d). All of these

Answer 1

Hint: A natural region is a geographical unit which has common geographical features like climate , vegetation, geology etc. Equatorial region consists of the area around the equator which is at 0 degree latitude.

Complete answer: The equatorial region extends from 0 degrees to 10 degrees north and south. It covers almost 6% and has countries like Indonesia,Congo ,Equator etc.
Let us look at the options given to us
Option (A ) hot and wet climate throughout the year is correct as these places, due to being close to the equator, have ample sunshine throughout and grow tropical rainforest.
Option (B ) red and yellow soils of low fertility is correct too as these areas have soil which is poor in nutrients due to intense weathering caused by rainfall. High temperature and high rainfall causes the soil to leach and iron oxides remains giving it a red tint.
Option (C ) tall hardwood trees form a cover is correct too as the equatorial regions have trees like rosewood, mahogany and teak. The tropical forests in these areas are very dense and because of this trees grow taller, spreading their branches , to reach out for sunlight.

Therefore option (D ) all of the above is correct.

Note: One should note that wet equatorial climate is one of the classifications under Koppen classification of climates. It is one of the major climate types which has distinct features of temperature around 30 degree celsius, high rainfall and humidity with less annual temperature difference.
